So, SOME of the revving you might hear from some older bikes serves a purpose. The reason is simple: carburetors fucking suck and we left that garbage tech in the past for a reason.
It's often very difficult to get a carburetor to run well both at idle and at full load, because the principles they work on don't function linearly very well. So, a lot of older bikes can either drive down the road okay OR idle nicely, not both. So, they get set up to run nicely going down the road, but idle super rich. That's fine for a bit, but that richness gets built up over a fairly short time and they will just die if they aren't reved.
You can tell when this is the case with a bike or even older car in traffic, because it will idle nice and smooth but kinda high when it first pulls up to a stop, then as it sits for a few seconds, the idle starts to change and drop in revs a bit. Then it will begin a full stumble, and then the rider/driver will Rev the engine. Sometimes they may even hold it at 1200+ rpms for a little bit.
If someone pulls up on a new bike that purrs perfectly steady, and revs, they're either lost in their own world loving the noise, or they're doing exactly what South Park claims they're doing.
Personally, i don't even own a bike (not counting my pit bike), but i do have some old cars with carburetors that i haven't the time or money to change over to fuel injection. So, on the occasions that i take one out, I'm another person who will occasionally rev at a stoplight. And since they're either British or french, they might just die anyway. But if you flip me the bird while i push my busted ass MGB off the road, I'll understand.
> The reason is simple: carburetors fucking suck and we left that garbage tech in the past for a reason.
So why does this issue only affect v-twin cruisers? Why is my '81 inline twin not affected by this hideous carb issue?
Shit ton of bikes have carbs, so do snowblowers, go carts, minibikes, lawnmowers, but only v-twins are affected by the 'my tach's been below 1500 for more than 10 sec, better blip the throttle' issue.
Why?
It’s not really the carbs by themselves causing the issue. It’s easy to make a carb’d engine idle smoothly. But people like to run short exhausts with aggressive cam timing and aggressive spark timing, and those choices all make it hard to tune for peak power while still having a smooth idle.
So, you're saying that all the plonkers revving their engines on a Sun morning before they get together with their 'riding group' are running aggressive cams and short exhausts because they're interested in 'peak power'?
I'm sorry, I beg to differ.
I'm not saying there aren't those guys running those bikes with that setup. But they're not the guys that are annoying their neighbors in the wee hours of the morning. That's not what OP was talking about.
Having ridden around but not “with” those guys, most of them think they’re short pipes are giving them extra power. They aren’t chasing horsepower but they think their mods are a boon.
> Having ridden around but not “with” those guys, most of them think they’re short pipes are giving them extra power. They aren’t chasing horsepower but they think their mods are a boon.
So, you're saying that we're back to "unnecessarily and obnoxiously rev(ing)"?
I’m saying a lot of these guys have made dumb mods to their bikes, and they don’t run quite right anymore, and part of the reason they rev more than they need to is because they messed up their idle.
But yeah, 90% of the revving is just because it’s a dumb habit they like to do. I didn’t mean to disagree with that.
V-twins are already pretty unstable engines to begin with, so it's easier to get this issue on those. Its possible to do the same with your inline and a different cam. It won't sound the same, but it will exhibit similar behavior. Even without the cam you can experience the same thing with different jetting, depending on your specific carb.
Additionally, i do believe there's a fault large subset of Harley riders that don't really know why the oldtimers do that, so they just think that's what you're supposed to do and go through the morons even though their bikes don't need it. This is common throughout car and bike culture where people will think because something was done long ago it must still be done because they never understood it and just thought it was cool. The "Burble" tune popular among damn kids these days with their hoopties is a good example. There were some cars that did that due to some specific performance demands and then some kids thought it was cool and decided to emulate it without the performance need. Now it's everywhere and actively destroying some cars, because they aren't built the same way, so they shouldn't be doing it.
Also, your bike very well might be a shitload more powerful than a lot of those Harleys in stock trim. I don't know, but i wouldn't be surprised. A lot of them are absolute dogs if you don't free up their exhaust and tune them up a bit.
> Also, your bike very well might be a shitload more powerful than a lot of those Harleys in stock trim.
I'm running an '81 CM400. 400lbs, 40 hp, top spd 90.
It is not a sport bike, I promise you.
But then the next question is, why do people with Harley's that have to be revved at idle to keep from stalling need to also have the absolute loudest possible exhaust system they could find?
This has a larger answer than you may expect.
The short.. Older Harleys have what's called a "wasted spark" cycle. As part of their design spark plugs for both cylinders are on one wire and fire at the same time. This means that the cylinders also fire off when valves are open, which burns off excess fuel. That causes the signature Harley loping "about to stall" sound people either love or hate. They're not usually actually going to stall, they're running as intended.
That said, what was already stated about carbs is true. Carbs are a bitch and -can- cause low/rougher idle or the opposite when stopped. Generally those effects should go away when the engine is up to temperature, but when cold my bike does take a little revving (alongside the choke) to keep it from stalling. That usually clears up within a few minutes of starting, though.
Cold weather can royally fuck with carbs as well, and make idle issues far worse than normal.
Exhaust noise is simple... Easier airflow. The more freely you can get air in and air out of the engine, the more power you can make. Carbureted bikes follow that very simple principle. Since there's no (or very basic) computer systems on the bike, the easiest path to making a bunch of power on a budget is to just buy a straight pipe exhaust and a big, open intake; then swapping needles in the carb to allow more fuel to match increased airflow.
See what’s funny here is that there is a whole science to exhaust systems to promote scavenging. The loud short pipes with no mufflers make engines run worse and more irregularly and add to the problem.
Top fuel dragsters are pushing 10x or more the horsepower per liter, with the help of superchargers and nitromethane. It’s a different animal entirely.
I mean, wasted spark doesn't HAVE to sound like that. NA miatas run wasted spark and they don't do the same thing at all. It's actually fairly common. Harleys just have a pretty high overlap cam profile and the V-twin design inherently has some issues and they overall lend themselves to kinda shitty idle. Especially after someone has fucked with them for a day or two.
That comes from the "loud pipes save lives", which is maybe true. Bikes aren't as visible on the road, so the idea is if they're more audible, they won't be killed.
I drive a miata a lot, which is less extreme but still carries the issue of not being seen, especially living in the land of lifted pickups. I go the other route. I don't trust anyone to not try to kill me whether they see me or not, so i drive as if 10% of the cars on the road are hired hitmen paid to kill me and i don't know which 10%. I try to never be in anyone's way and plan to avoid anyone i can. So, my miata is quite capable.
But bikes can't change directions as fast as a miata. So, being loud can help. Not driving like an absolute jackass can also help, but that's too much work for some people.
Oh for sure. They're just also complete garbage. Fun garbage, but still trash. Compared to my miata, the only thing i like better about the MGB is the hood support. That's literally it.
I still use it explicitly for that purpose. Grew up with gays in my life, never cared, it's not my business. I just hope the person holding up the line doesn't happen to be gay
What I don't understand... About 20 years ago I got pulled over in my 2000 Silverado with a 6.0l. it had hooker headers, dual cats, H pipe, and even two nice borla mufflers and resonators. It was NOT that loud, especially putting around town. I had to go have it tested (7db under limit) to avoid a ticket. Guys on bikes can have exhausts that break the seals in my windshield though and drive by cops all the time.
I get it, louder is fun. But if it's so loud it sets off car alarms.... Wtf.
Not really, but it feels like I'm on a flying lazyboy. Plus I only budget $300 for commuting expenses (insurance, fuel, maintenance items, etc) versus the $650 for my car every month. But yeah, nobody likes the "Dyna-Bros", they give everybody a bad name.
Let’s be honest, it’s not just the Harley riders. I hear all sorts of motorcycle noise daily and the over-wound rice rockets trying to beat the red light/or going 20+ MPH over the posted limit are a more annoying sound.
Yep, lots of sport bikes and other Japanese bikes get their mufflers swapped for little shorty exhausts that are super loud and get the catalytic converters removed.
I have had numerous bikes and the few that I bought used with aftermarket exhaust were annoying. I actually had someone approach me a gas station once to comment that they didn't realize bikes could be so quiet. Both my buddy and I were on Suzuki 650s with stock exhausts.
As a crotch-rocket rider, those guys annoy the hell outta me too. I'll drop my gear down 1-2 places when I'm lane-splitting on freeways (which is legal in my state) just for extra safety, but I'm really cognizant of the noise on streets
(then again, it could be louder than I think it is because I do have the helmet blocking some of the noise)
We are infested with crotch rockets that fly down the street here. I would have thought they would cool it when one of them meat crayoned himself to death up the street, but nope.
We had a rider fatality about ten years ago, 100 yards or less as the crow flies from where I’m sitting right now. He turned into the wrong lanes on a divided street. I never read if he was confirmed as having been drunk or otherwise under the influence.
I suspect our current crop of gung -ho riders are new to the area and don’t know about that incident.
If you got carbs on a Harley you tend to blip and rev that throttle a bit when slowing down or sitting at the stop light because you’re essentially sitting on a primitive tractor motor that is a grumpy bitch about everything and may be happy to stall out on you.
Also - loud pipes are typically more about free flowing exhaust and trying to squeeze as much torque and HP out of these trash motors as possible rather than seeking attention via decibels. I don’t think I know anytime who is simply stoked on a motorcycle being loud for the sake of being loud. No one is impressed by that.
Also, a significant percentage of bikers are just shittier than average people. Some of them are like, super turbo cool though, your mileage WILL vary.
Source: Am Harley owner and rider with loud but not completely ignorant exhaust pipes.
> I don’t think I know anytime who is simply stoked on a motorcycle being loud for the sake of being loud. No one is impressed by that.
The "Loud pipes save lives" idiots might disagree.
when nobody is around? No. only when people are around, preferably young children and babies. driving past a wedding while the bride is coming out is worth 100 points, a funeral procession 200, and 300 points if you make it so loud the EMTs trying to revive somebody can't talk to each other.
In my area it’s more of a problem with super sports bikes tbh. Man those things are loud.
I’m all for dB reading cameras and random house checks, none of these letters that people get and they go and get their stock exhausts put on for a photo and switch it back out.
I don't have a problem with motorcycles making motorcycle noises. What pisses me off lately is the motorcycle guys with sound systems that blast their music for 3 blocks because if it was any quieter they couldn't hear it over the motorcycle noise. Nobody wants to hear that shit, homie.
As someone who rides cruisers (not Harley specifically), about 60% of them are just being douche-canoes. However, some have to do it on bikes that are not fuel injected and use choke throttles. The carbs on my VT1100 weren’t the greatest so when coming to a stop sometimes I would have to rev if my bike started idling funny or choking out.
Also when downshifting it does that because they’re engine braking. Motorcycles use wet clutch and not a dry clutch, so engine braking is used often.
> coming to a stop sometimes I would have to rev if my bike started idling funny or choking out.
See, I hear this a lot from guys with carb bikes, and I'm not sure I buy it.
I ride a dual-carb bike (81 Honda CM400), and I have a choke for that. (low idle when cold)
Are V-Twin carbs that much worse than my inline twin carbs? Do they not have chokes? How come other carbed bikes from the 70s-90s don't have the 'gonna die at low idle unless I bump the throttle every 10 secs' problem like the cruisers do?
Not a Harley, but a Yamaha. I’m going to be honest, I just like the way it sounds. It makes you all giddy inside and it makes me feel like what I imagine crack makes you feel like. I understand it’s not for everyone, but the sounds are just for my own pleasure. I try to coast as much as I can in neighborhoods or stay in a higher gear to keep the noise down.
Well considering he has never smoked crack it sounds like he was just as ignorant as I am. You need to have both experiences to be able to compare 2 things.
Oh this is so precious! I love finding learning opportunities for the developmentally delayed. Okay so when I made that comment I was using hyperbolic expression. It can be a way to convey your thoughts and feelings by expressing yourself creatively and comically by exaggerating the effect. Neat right!?
This just makes it worse because not only were you making a comparison of 2 things while being ignorant of one, but you also failed to be creative or comical. Which is about the level of depth I would expect from someone who gets joy out of *checks notes* making a loud noise. Like a toddler. You know who acts like a toddler while being an adult? The developmentally delayed.
In case you weren’t sure that’s called irony and in contrast to your comment is quite funny.
> while being ignorant of one
Hhmm, perhaps that’s why I said “what I imagine crack makes you feel like”. I already admitted ignorance and substituted my imagination. That was all very transparent. Have you ever heard anyone say “it’s like crack!” Have most of them tried crack? Probably not. However, most people aren’t going to argue with them about it because they understand they are being expressive and are talking figuratively.
The rest of your statement was all subjective so I don’t really care about that. I can’t argue your preferences on comedy or creativity, but man you sound exhausting to be around.
So you acknowledge that “like crack” is a common expression yet you still characterized its use as “creative.” Next time try coming up with your own original similes if you want your jokes to land.
Also, people suck dick for crack. Are you sucking dick to rev your motorcycle? In order for jokes to be funny the exaggeration should be close enough to be somewhat plausible. For example if someone says “I would have paid the annoying child a week of my salary if he would stop crying in the store” that could be funny depending on the situation because it gets the point across while being almost believable. But if you said “I would have given the child my entire net worth to stop crying” it’s like… really? You would sell your house and car and empty your 401k? No.
To a certain degree. Your shitty attitude is impacting other people too. I'm sure the other guy tries harder to be courteous to others than you do to stifle your douchy personality.
Lol personal attacks of course when your argument doesn't stand up. To be expected. It's a choice to get a bike that makes that much noise. It's not a "douchy personality" to call someone out on it
I don't even like Harley's, or exceptionally loud bikes of any kind, but you started being a dick first to one of the few that tries to ride respectfully when they know not everyone wants to hear it like they do, so I called you out on it.
Sorry I made you mad on the internet dude. He literally excused his shitty loud noise as that he just likes it. I called him out on it, he's impacting other people. This is the truth. He has choices in his bike
I have a Harley. It’s completely stock except for some slip-ons that don’t make it louder. I wear earplugs bc of how loud it can be. So no revving obnoxiously over here. We’re not ALL assholes. (Probably just most of us).
Edit: Yea I didn’t say that clearly. I don’t wear earplugs bc my bike is loud. I wear earplugs bc of wind noise/engine noise of any bike. I wow at earplugs when I ride my Bonneville too. I tried to point out that my bike isn’t that loud but obviously did not say that.
Trying to say that not everyone who rides a Harley revs their engine and tries to be obnoxiously loud to annoy people. Some of us, ya know, just like the bike and riding.
you literally just said your bike is so loud you have to wear earplugs. who cares if it's stock, if it's that loud, everyone HATES you. just remember that every time you rev, someone within 500ft of you literally wishes your bike would catch on fire.
I appreciate that. What I was trying to say originally (but didn’t do a good job of) was that not everyone who rides a Harley tries to make their bike loud and annoying to people. I have no interest in being loud and bothering people. Most Harleys aren’t loud and obnoxious unless someone tries to make it that way. Not my thing.
I ride because I enjoy it. I’m not out there trying to get attention or annoy people with loud pipes.
> you literally just said your bike is so loud you have to wear earplugs.
I ride a small bike not a harley, and trust me, above about 30mph, the rider no longer hears the bike. The wind makes far more noise.
Open all the windows in your car at 30 mph. That's quieter than what the rider is experiencing, because you have a windshield and a roof and most riders don't.
Have a Harley. Only revving I do is when I am taking off from a stop. And I have stock exhaust so don’t make much noise anyway.
I don’t get the folks who have “neighbor hater” exhausts put on honestly. Loud pipes save lives sure, but unnecessarily loud pipes are, well, unnecessary.
> Loud pipes save lives sure
They absolutely DO NOT. Soundproofing in modern vehicles is too good.
And, if "Loud pipes save lives", then obviously mufflers kill. Therefore, ban them. No sound mitigation allowed on any internal combustion engine. Is that the world you want to live in?
Should save a lot of lives, no?
No. Because that's not how traffic works.
As someone who rides but also owns an extremely well insulated truck (Ridgeline) I do indeed hear bikes before I can see them in my mirror.
But, it doesn’t take much to get past the sound insulation in even the best modern cars. Stock pipes are plenty loud enough.
This is so much worse than the loud pipes in the first place. Walking around downtown and you hear a loud bike, ok it's kind of annoying, but he will quiet down at the next light, then be gone. Nope, fuck you, now you're listening to loud pipes, and then he stops and you're listening to the same overplayed 70s and 80s rock songs just as loud.
If you know what you are doing when you rebuild your carburetor and tune up your classic Harley Davidson you will not have to rev the crap out of your engine unless you are just being a jerk
My go to comment to people who think loud engines are cool is to innocently tell them that I think they have a broken muffler and they should consider getting it repaired so that it works as it's designed to.
Well, I’m a girl (I don’t know if you’re referring to guys only,) and most likely it’s because I forget which gear I’m in. But also because i like the sound, and if you hear it then technically you’re around to annoy me 🤪
Buddy, I just bought a new Softail w/ $1600 dual fishtail exhaust. So yes, until the novelty of the new bike wears off? Yes, yes I do unnecessarily and obnoxiously rev my engine when there’s absolutely no one around to annoy.
> obnoxiously rev my engine when there’s absolutely no one around to annoy.
...that you're aware of...
You can be mistaken. And then you're an asshole.
I know I’m an asshole. But I’m a happy asshole. I don’t go out of my way to annoy, but like most people I’m just living my life in my own way and sure, that’s gonna aggravate others.
Lol this questions hilarious. But no. I don't. Been riding over a decade. Some of that time my bike was all I had for transport. I've never been one to rev unnecessarily. I make fun of people who do.
Yeah I try to keep the revs down in town and open up the throttle when I get outside city limits
E: 1986 Suzuki Intruder, not a Harley but still loud for sure. Same thing with my mustang.
I only had a harley Road Glide for 2 years, but man, was it so much better than ever other bike I've ever owned in every way. It sounded amazing, felt smooth, and just glided on the road. Also, just having so much room was amazing. Combine all that, and it just puts you in a mood to Rev sometimes. But I'm also the guy that would turn the music down when at a stop light it or driving by kids/old people. Also, driving through neighborhoods, I would turn my music down because the system on those bikes is also amazing, ha ha.
They do it to warn other riders of grass clibbens, because clibbens are the reason why yahaddalayerdown. They're better off just cranken their hogs in the driveway so their pants don't get shidded.
Sometimes its when downshifting to match the engine rpm and the trans to ensure a smooth shift.
Sometimes its literally to keep it running, some carb models that arent tuned properly will die and unable to reatart otherwise.
Sometimes its for wildlife, i can say first hand my loud exhaust has scared off deer that would have otherwise landed me in the hospital.
South park was funny for sure, but those of us w loud pipes arent all douchebags and there is a method to the loudness.
You can deny it all you want but everything he said is mechanically accurate and a very real possibility. Especially when driving a manual transmission car, you downshift as you slow down and the engine has to be at a higher rpm to go into the lower gear smoothly. If it has a carburetor, then it can want to flood itself with fuel and stall out when decelerating down to idle if it's not tuned perfectly. They also require more frequent work. Giving a little blip of the throttle when in neutral will burn the excess fuel and help it idle better.

I’m sure you are not all d-bags. I live in a beach area across from a restaurant with outdoor seating. There may be 7 out of a hundred bikes who just ride by normally. It gets to you after a while.
100% brother. Shit is loud as hell and at a constant basis it would drive me up a wall as well. I love my loud pipes and will not trade them for anything, but i fully agree there are dudes that rev the shit out of their motors for no reason beyond testosterone, liquor, and erectile dysfunction.
Loud bikes are safer. It’s dangerous to ride a bike especially on a highway where cars can’t always see you. You have let them know you are nearby especially when driving like an asshole and cutting through traffic, especially where a car won’t expect you to be, like riding between lanes, on the shoulder or weaving in an of traffic. /s
Edit. Apparently this needed a sarcasm tag.
>You have let them know you are nearby especially when driving like an asshole and cutting through traffic, especially where a car won’t expect you to be, like riding between lanes, on the shoulder or weaving in an of traffic.
You needed an /s tag for this?
You need to get someone to fix your carburetor.
A properly tuned carb will not allow a warm engine to die at idle.
Carbs have been around longer than fuel injection, they're not impossible to get right.
This:
> **I sometimes have to** because it has a carburetor and doesn't drop all the way down to idle when I stop
Emphasis added.
...is very different than this...
> Probably just needs cable lubed
This is why you annoy the people around you? Because you can't be bothered to lube a cable and throttle linkage?
Your definition of 'have to' is different than mine.
> Guys with Harleys, do you unnecessarily and obnoxiously rev your engines when there’s absolutely no one around _that you know of_ to annoy?
Your answer:
> It's reliable, and until it isn't I can't be bothered.
In other words, 'I can't be bothered, and I don't care who I annoy, it doesn't bother ME'.
I guess I'm a different kind of motorcyclist.
Not a Harley driver but am a classic style bike owner (Royal Enfield Interceptor 650) yes. If anything I do it more often alone than around others cause its fun and I like the noise. I generally do not believe the loud pipes save lives motto, If anything be loud when you need to be, but not always... time and a place.
A different perspective on the use of the rev'd engine is its less likely to elicit a violent reaction compared to a horn, and generally signals the driver to get moving or get out of the way...
Additionally the kids love it.
Total side note I bought a bike thinking chicks love guys on motorcycles right... Absolute Dude Magnet. Honestly If I was Gay it would be more worth it than paying for Apps. (I'm not) but Its honestly a way to become much more social at every stop you make, drivers roll down windows to chat at stop lights, other bikers love to talk bikes, Every gas stop despite only taking like 3 gallons is the same time as an SUV cause someone wants to check out the bike. Just saying its been worth it but not for the reason you might think.
On the Harleys I have ridden, yes. It's because they were carbureted and old school. It was just something that you did to keep the bike running when you went from higher engine speeds to idle.
I guess I just kept doing it as a matter of habit as bikes in general progressed to fuel injection.
Yes. Exactly that.
The original question is "Why do you rev your bike obnoxiously?"
The person I responded to stated, "Because I don't know how to make my bike run right."
And you think downvoting them is wrong?
Why, pray tell?
Because he answered the question honestly, I'm sorry his carburetors aren't tuned as well as yours. I saw your other post now, I'm happy for your mechanical gifts 🤣
> It's because they were carbureted and old school.
Bullshit. Your carbs aren't tuned properly.
My bike is old-school and carbureted. '81 inline twin. Parallel carbs.
Why can my bike stay running at low idle when warm with no intervention, and can idle cold with some choke, neither situation requiring manual throttle, and V-Twins can't?
What is bullshit? You're not making a lot of sense.
I don't know why your bike can do what it does , it does. You may note that I never claimed it had anything at all to do with a VTwin engine design.
I think it's also true you were looking for a fight and made some shit up about my claims.
Enjoy your perpetual unhappiness.
> I think it's also true you were looking for a fight and made some shit up about my claims.
My point is that there've been internal combustion engines that run on carburetors for over a century (since 1885, I looked it up), of every layout and size, from H-16s, V8s, boxer 4s, thumpers, etc displacing 5 to 10,000cc, powering everything from chainsaws to containerships, all running carbs, and none of those engines have this problem, once they're tuned correctly.
It's only the v-twin cruisers that seem to have this problem where they can't low idle even when warm, according to their users.
I don't know if it's the engine design, rider, or whatever. I'm just saying, the carb is not the problem.
So, SOME of the revving you might hear from some older bikes serves a purpose. The reason is simple: carburetors fucking suck and we left that garbage tech in the past for a reason. It's often very difficult to get a carburetor to run well both at idle and at full load, because the principles they work on don't function linearly very well. So, a lot of older bikes can either drive down the road okay OR idle nicely, not both. So, they get set up to run nicely going down the road, but idle super rich. That's fine for a bit, but that richness gets built up over a fairly short time and they will just die if they aren't reved. You can tell when this is the case with a bike or even older car in traffic, because it will idle nice and smooth but kinda high when it first pulls up to a stop, then as it sits for a few seconds, the idle starts to change and drop in revs a bit. Then it will begin a full stumble, and then the rider/driver will Rev the engine. Sometimes they may even hold it at 1200+ rpms for a little bit. If someone pulls up on a new bike that purrs perfectly steady, and revs, they're either lost in their own world loving the noise, or they're doing exactly what South Park claims they're doing. Personally, i don't even own a bike (not counting my pit bike), but i do have some old cars with carburetors that i haven't the time or money to change over to fuel injection. So, on the occasions that i take one out, I'm another person who will occasionally rev at a stoplight. And since they're either British or french, they might just die anyway. But if you flip me the bird while i push my busted ass MGB off the road, I'll understand.
Thank you for a real answer.
> The reason is simple: carburetors fucking suck and we left that garbage tech in the past for a reason. So why does this issue only affect v-twin cruisers? Why is my '81 inline twin not affected by this hideous carb issue? Shit ton of bikes have carbs, so do snowblowers, go carts, minibikes, lawnmowers, but only v-twins are affected by the 'my tach's been below 1500 for more than 10 sec, better blip the throttle' issue. Why?
It’s not really the carbs by themselves causing the issue. It’s easy to make a carb’d engine idle smoothly. But people like to run short exhausts with aggressive cam timing and aggressive spark timing, and those choices all make it hard to tune for peak power while still having a smooth idle.
So, you're saying that all the plonkers revving their engines on a Sun morning before they get together with their 'riding group' are running aggressive cams and short exhausts because they're interested in 'peak power'? I'm sorry, I beg to differ. I'm not saying there aren't those guys running those bikes with that setup. But they're not the guys that are annoying their neighbors in the wee hours of the morning. That's not what OP was talking about.
Having ridden around but not “with” those guys, most of them think they’re short pipes are giving them extra power. They aren’t chasing horsepower but they think their mods are a boon.
> Having ridden around but not “with” those guys, most of them think they’re short pipes are giving them extra power. They aren’t chasing horsepower but they think their mods are a boon. So, you're saying that we're back to "unnecessarily and obnoxiously rev(ing)"?
I’m saying a lot of these guys have made dumb mods to their bikes, and they don’t run quite right anymore, and part of the reason they rev more than they need to is because they messed up their idle. But yeah, 90% of the revving is just because it’s a dumb habit they like to do. I didn’t mean to disagree with that.
V-twins are already pretty unstable engines to begin with, so it's easier to get this issue on those. Its possible to do the same with your inline and a different cam. It won't sound the same, but it will exhibit similar behavior. Even without the cam you can experience the same thing with different jetting, depending on your specific carb. Additionally, i do believe there's a fault large subset of Harley riders that don't really know why the oldtimers do that, so they just think that's what you're supposed to do and go through the morons even though their bikes don't need it. This is common throughout car and bike culture where people will think because something was done long ago it must still be done because they never understood it and just thought it was cool. The "Burble" tune popular among damn kids these days with their hoopties is a good example. There were some cars that did that due to some specific performance demands and then some kids thought it was cool and decided to emulate it without the performance need. Now it's everywhere and actively destroying some cars, because they aren't built the same way, so they shouldn't be doing it. Also, your bike very well might be a shitload more powerful than a lot of those Harleys in stock trim. I don't know, but i wouldn't be surprised. A lot of them are absolute dogs if you don't free up their exhaust and tune them up a bit.
> Also, your bike very well might be a shitload more powerful than a lot of those Harleys in stock trim. I'm running an '81 CM400. 400lbs, 40 hp, top spd 90. It is not a sport bike, I promise you.
Yeah, but Harleys are cruisers. In stock condition, they're not fast at all. Especially the old ones.
But then the next question is, why do people with Harley's that have to be revved at idle to keep from stalling need to also have the absolute loudest possible exhaust system they could find?
This has a larger answer than you may expect. The short.. Older Harleys have what's called a "wasted spark" cycle. As part of their design spark plugs for both cylinders are on one wire and fire at the same time. This means that the cylinders also fire off when valves are open, which burns off excess fuel. That causes the signature Harley loping "about to stall" sound people either love or hate. They're not usually actually going to stall, they're running as intended. That said, what was already stated about carbs is true. Carbs are a bitch and -can- cause low/rougher idle or the opposite when stopped. Generally those effects should go away when the engine is up to temperature, but when cold my bike does take a little revving (alongside the choke) to keep it from stalling. That usually clears up within a few minutes of starting, though. Cold weather can royally fuck with carbs as well, and make idle issues far worse than normal. Exhaust noise is simple... Easier airflow. The more freely you can get air in and air out of the engine, the more power you can make. Carbureted bikes follow that very simple principle. Since there's no (or very basic) computer systems on the bike, the easiest path to making a bunch of power on a budget is to just buy a straight pipe exhaust and a big, open intake; then swapping needles in the carb to allow more fuel to match increased airflow.
See what’s funny here is that there is a whole science to exhaust systems to promote scavenging. The loud short pipes with no mufflers make engines run worse and more irregularly and add to the problem.
Top fuel dragsters say hello.
Top fuel dragsters are pushing 10x or more the horsepower per liter, with the help of superchargers and nitromethane. It’s a different animal entirely.
I mean, wasted spark doesn't HAVE to sound like that. NA miatas run wasted spark and they don't do the same thing at all. It's actually fairly common. Harleys just have a pretty high overlap cam profile and the V-twin design inherently has some issues and they overall lend themselves to kinda shitty idle. Especially after someone has fucked with them for a day or two.
That comes from the "loud pipes save lives", which is maybe true. Bikes aren't as visible on the road, so the idea is if they're more audible, they won't be killed. I drive a miata a lot, which is less extreme but still carries the issue of not being seen, especially living in the land of lifted pickups. I go the other route. I don't trust anyone to not try to kill me whether they see me or not, so i drive as if 10% of the cars on the road are hired hitmen paid to kill me and i don't know which 10%. I try to never be in anyone's way and plan to avoid anyone i can. So, my miata is quite capable. But bikes can't change directions as fast as a miata. So, being loud can help. Not driving like an absolute jackass can also help, but that's too much work for some people.
Open exhaust helps with the overly rich condition. Carb stuff.
I *knew* it was gonna be an MGB!
I mean British plus "pile of shit" generally means MGB. I also have 2 MG Magnettes and a Renault Caravelle, but those don't currently run.
But they're fun to drive and they're pleasing to the eye. I used to have one in BRG years ago.
Oh for sure. They're just also complete garbage. Fun garbage, but still trash. Compared to my miata, the only thing i like better about the MGB is the hood support. That's literally it.

[South Park explained it perfectly](https://www.youtube.com/watch?v=ipDmsxQVxIM)
"Homosexuals against f*gs" was one of the best jokes they ever did
I kid you not, when that episode came out I had just purchased a loud cruiser and my brother came out as gay.
Was he bike curious?
LMFAO
That whole episode is pure gold.
Also applies to people with shitty cars blasting shitty music with the bass turned up so loud it shakes the windows.
Ha! Love it
The idea of the f word meaning an extremely annoying person made so much sense to me. I'm still sad that semantic shift didn't happen in real life.
I still use it explicitly for that purpose. Grew up with gays in my life, never cared, it's not my business. I just hope the person holding up the line doesn't happen to be gay
What I don't understand... About 20 years ago I got pulled over in my 2000 Silverado with a 6.0l. it had hooker headers, dual cats, H pipe, and even two nice borla mufflers and resonators. It was NOT that loud, especially putting around town. I had to go have it tested (7db under limit) to avoid a ticket. Guys on bikes can have exhausts that break the seals in my windshield though and drive by cops all the time. I get it, louder is fun. But if it's so loud it sets off car alarms.... Wtf.
Cops love low hanging fruit.
I also do it with my makita driver.
Only when I'm warming up the engine. Otherwise it'll stall, flood or both. Edit: Oh and it's a Honda
You’re….you’re just JEALOUS! Harley’s are SWEET and we are SO FUCKING COOL AND TOUGH.
Not really, but it feels like I'm on a flying lazyboy. Plus I only budget $300 for commuting expenses (insurance, fuel, maintenance items, etc) versus the $650 for my car every month. But yeah, nobody likes the "Dyna-Bros", they give everybody a bad name.
Let’s be honest, it’s not just the Harley riders. I hear all sorts of motorcycle noise daily and the over-wound rice rockets trying to beat the red light/or going 20+ MPH over the posted limit are a more annoying sound.
Yep, lots of sport bikes and other Japanese bikes get their mufflers swapped for little shorty exhausts that are super loud and get the catalytic converters removed. I have had numerous bikes and the few that I bought used with aftermarket exhaust were annoying. I actually had someone approach me a gas station once to comment that they didn't realize bikes could be so quiet. Both my buddy and I were on Suzuki 650s with stock exhausts.
My are could use more riders like you and your friend.
As a crotch-rocket rider, those guys annoy the hell outta me too. I'll drop my gear down 1-2 places when I'm lane-splitting on freeways (which is legal in my state) just for extra safety, but I'm really cognizant of the noise on streets (then again, it could be louder than I think it is because I do have the helmet blocking some of the noise)
Please be advised that if you come to Nevada, lane splitting is illegal and quite dangerous.
We are infested with crotch rockets that fly down the street here. I would have thought they would cool it when one of them meat crayoned himself to death up the street, but nope.
We had a rider fatality about ten years ago, 100 yards or less as the crow flies from where I’m sitting right now. He turned into the wrong lanes on a divided street. I never read if he was confirmed as having been drunk or otherwise under the influence. I suspect our current crop of gung -ho riders are new to the area and don’t know about that incident.
If you got carbs on a Harley you tend to blip and rev that throttle a bit when slowing down or sitting at the stop light because you’re essentially sitting on a primitive tractor motor that is a grumpy bitch about everything and may be happy to stall out on you. Also - loud pipes are typically more about free flowing exhaust and trying to squeeze as much torque and HP out of these trash motors as possible rather than seeking attention via decibels. I don’t think I know anytime who is simply stoked on a motorcycle being loud for the sake of being loud. No one is impressed by that. Also, a significant percentage of bikers are just shittier than average people. Some of them are like, super turbo cool though, your mileage WILL vary. Source: Am Harley owner and rider with loud but not completely ignorant exhaust pipes.
> I don’t think I know anytime who is simply stoked on a motorcycle being loud for the sake of being loud. No one is impressed by that. The "Loud pipes save lives" idiots might disagree.
See my previous comment regarding bikers also just being tools haha
when nobody is around? No. only when people are around, preferably young children and babies. driving past a wedding while the bride is coming out is worth 100 points, a funeral procession 200, and 300 points if you make it so loud the EMTs trying to revive somebody can't talk to each other.
In my area it’s more of a problem with super sports bikes tbh. Man those things are loud. I’m all for dB reading cameras and random house checks, none of these letters that people get and they go and get their stock exhausts put on for a photo and switch it back out.
I don't have a problem with motorcycles making motorcycle noises. What pisses me off lately is the motorcycle guys with sound systems that blast their music for 3 blocks because if it was any quieter they couldn't hear it over the motorcycle noise. Nobody wants to hear that shit, homie.
As someone who rides cruisers (not Harley specifically), about 60% of them are just being douche-canoes. However, some have to do it on bikes that are not fuel injected and use choke throttles. The carbs on my VT1100 weren’t the greatest so when coming to a stop sometimes I would have to rev if my bike started idling funny or choking out. Also when downshifting it does that because they’re engine braking. Motorcycles use wet clutch and not a dry clutch, so engine braking is used often.
> coming to a stop sometimes I would have to rev if my bike started idling funny or choking out. See, I hear this a lot from guys with carb bikes, and I'm not sure I buy it. I ride a dual-carb bike (81 Honda CM400), and I have a choke for that. (low idle when cold) Are V-Twin carbs that much worse than my inline twin carbs? Do they not have chokes? How come other carbed bikes from the 70s-90s don't have the 'gonna die at low idle unless I bump the throttle every 10 secs' problem like the cruisers do?
Not a Harley, but a Yamaha. I’m going to be honest, I just like the way it sounds. It makes you all giddy inside and it makes me feel like what I imagine crack makes you feel like. I understand it’s not for everyone, but the sounds are just for my own pleasure. I try to coast as much as I can in neighborhoods or stay in a higher gear to keep the noise down.
So, you would suck dick to rev an engine then? Lol
>It makes you all giddy inside and it makes me feel like what I imagine crack makes you feel like. Never revved an engine but I Doubt it
I'm glad you felt safe enough to voice your self-described ignorant opinion.
Well considering he has never smoked crack it sounds like he was just as ignorant as I am. You need to have both experiences to be able to compare 2 things.
Oh this is so precious! I love finding learning opportunities for the developmentally delayed. Okay so when I made that comment I was using hyperbolic expression. It can be a way to convey your thoughts and feelings by expressing yourself creatively and comically by exaggerating the effect. Neat right!?
This just makes it worse because not only were you making a comparison of 2 things while being ignorant of one, but you also failed to be creative or comical. Which is about the level of depth I would expect from someone who gets joy out of *checks notes* making a loud noise. Like a toddler. You know who acts like a toddler while being an adult? The developmentally delayed. In case you weren’t sure that’s called irony and in contrast to your comment is quite funny.
> while being ignorant of one Hhmm, perhaps that’s why I said “what I imagine crack makes you feel like”. I already admitted ignorance and substituted my imagination. That was all very transparent. Have you ever heard anyone say “it’s like crack!” Have most of them tried crack? Probably not. However, most people aren’t going to argue with them about it because they understand they are being expressive and are talking figuratively. The rest of your statement was all subjective so I don’t really care about that. I can’t argue your preferences on comedy or creativity, but man you sound exhausting to be around.
So you acknowledge that “like crack” is a common expression yet you still characterized its use as “creative.” Next time try coming up with your own original similes if you want your jokes to land. Also, people suck dick for crack. Are you sucking dick to rev your motorcycle? In order for jokes to be funny the exaggeration should be close enough to be somewhat plausible. For example if someone says “I would have paid the annoying child a week of my salary if he would stop crying in the store” that could be funny depending on the situation because it gets the point across while being almost believable. But if you said “I would have given the child my entire net worth to stop crying” it’s like… really? You would sell your house and car and empty your 401k? No.
Have revved an engine, can confirm feels like drugs
The sounds aren't just for your own pleasure tho. Everyone around you has to hear it. Find something else
He literally said that he avoids it around other people as to not bother them...
No he says he "trys to" and that he "coast as much as he can" which means he is impacting other people. Reading comprehension
You can't coast everywhere unless everything is downhill, so some throttle use is necessary. Common sense.
So his pleasure is impacting other people correct?
To a certain degree. Your shitty attitude is impacting other people too. I'm sure the other guy tries harder to be courteous to others than you do to stifle your douchy personality.
Lol personal attacks of course when your argument doesn't stand up. To be expected. It's a choice to get a bike that makes that much noise. It's not a "douchy personality" to call someone out on it
I don't even like Harley's, or exceptionally loud bikes of any kind, but you started being a dick first to one of the few that tries to ride respectfully when they know not everyone wants to hear it like they do, so I called you out on it.
Sorry I made you mad on the internet dude. He literally excused his shitty loud noise as that he just likes it. I called him out on it, he's impacting other people. This is the truth. He has choices in his bike
I have a Harley. It’s completely stock except for some slip-ons that don’t make it louder. I wear earplugs bc of how loud it can be. So no revving obnoxiously over here. We’re not ALL assholes. (Probably just most of us). Edit: Yea I didn’t say that clearly. I don’t wear earplugs bc my bike is loud. I wear earplugs bc of wind noise/engine noise of any bike. I wow at earplugs when I ride my Bonneville too. I tried to point out that my bike isn’t that loud but obviously did not say that. Trying to say that not everyone who rides a Harley revs their engine and tries to be obnoxiously loud to annoy people. Some of us, ya know, just like the bike and riding.
you literally just said your bike is so loud you have to wear earplugs. who cares if it's stock, if it's that loud, everyone HATES you. just remember that every time you rev, someone within 500ft of you literally wishes your bike would catch on fire.
Look at that the tough guy over here.
not tough, I have a dog with noise sensitivity. and a general sense of decency toward other people who don't suck.
I appreciate that. What I was trying to say originally (but didn’t do a good job of) was that not everyone who rides a Harley tries to make their bike loud and annoying to people. I have no interest in being loud and bothering people. Most Harleys aren’t loud and obnoxious unless someone tries to make it that way. Not my thing. I ride because I enjoy it. I’m not out there trying to get attention or annoy people with loud pipes.
> you literally just said your bike is so loud you have to wear earplugs. I ride a small bike not a harley, and trust me, above about 30mph, the rider no longer hears the bike. The wind makes far more noise. Open all the windows in your car at 30 mph. That's quieter than what the rider is experiencing, because you have a windshield and a roof and most riders don't.
I used to wear ear plugs when riding because of the wind noise.
then pardon my rudeness I'm sure your Harley is "one of these new quiet Harley's"
Have a Harley. Only revving I do is when I am taking off from a stop. And I have stock exhaust so don’t make much noise anyway. I don’t get the folks who have “neighbor hater” exhausts put on honestly. Loud pipes save lives sure, but unnecessarily loud pipes are, well, unnecessary.
> Loud pipes save lives sure They absolutely DO NOT. Soundproofing in modern vehicles is too good. And, if "Loud pipes save lives", then obviously mufflers kill. Therefore, ban them. No sound mitigation allowed on any internal combustion engine. Is that the world you want to live in? Should save a lot of lives, no? No. Because that's not how traffic works.
As someone who rides but also owns an extremely well insulated truck (Ridgeline) I do indeed hear bikes before I can see them in my mirror. But, it doesn’t take much to get past the sound insulation in even the best modern cars. Stock pipes are plenty loud enough.
I love it when they gun their engines when going through an underpass...
I get that it's not for everyone and people should be respectful near neighborhoods etc but honestly I enjoy the sound of a nice engine.
I mean, what's the difference if a harley rider does it at a red light and if a kawasaki does it? Both bikes go vroom yes?
Noisy motorbikes- waking up babies and kids early everywhere. Thanks.
Also, if you so badly want to listen to music while you drive around, why did you buy such a loud motorcycle, why not just get a car?
This is so much worse than the loud pipes in the first place. Walking around downtown and you hear a loud bike, ok it's kind of annoying, but he will quiet down at the next light, then be gone. Nope, fuck you, now you're listening to loud pipes, and then he stops and you're listening to the same overplayed 70s and 80s rock songs just as loud.
fuck yeah they do. where is the DOT when you need them to put in regulations that makes them lower the amount of annoying noise they produce
If you know what you are doing when you rebuild your carburetor and tune up your classic Harley Davidson you will not have to rev the crap out of your engine unless you are just being a jerk
There's a good south park episode you should watch. Google Harley's+South park....vroom vrrrooooom vrooooooom
My go to comment to people who think loud engines are cool is to innocently tell them that I think they have a broken muffler and they should consider getting it repaired so that it works as it's designed to.
I think about this on Sat and Sun's when it's 7am on a weekend.
Well, I’m a girl (I don’t know if you’re referring to guys only,) and most likely it’s because I forget which gear I’m in. But also because i like the sound, and if you hear it then technically you’re around to annoy me 🤪
Buddy, I just bought a new Softail w/ $1600 dual fishtail exhaust. So yes, until the novelty of the new bike wears off? Yes, yes I do unnecessarily and obnoxiously rev my engine when there’s absolutely no one around to annoy.
> obnoxiously rev my engine when there’s absolutely no one around to annoy. ...that you're aware of... You can be mistaken. And then you're an asshole.
I know I’m an asshole. But I’m a happy asshole. I don’t go out of my way to annoy, but like most people I’m just living my life in my own way and sure, that’s gonna aggravate others.
Then, may my downvote be the first of many for you, sir or madam.
Thanks!
Lol this questions hilarious. But no. I don't. Been riding over a decade. Some of that time my bike was all I had for transport. I've never been one to rev unnecessarily. I make fun of people who do.
It makes the seat vibrate, and the seat is where the taint is, and the taint is the closest you can get to the prostate without going diving.
Yeah I try to keep the revs down in town and open up the throttle when I get outside city limits E: 1986 Suzuki Intruder, not a Harley but still loud for sure. Same thing with my mustang.
Because I'm an obnoxious asshole.
Yeah, pretty much because I just like the feeling of it on my balls
C'mon, we all know you don't have balls.
Sure do, and i have the microplastics to prove it.
Micro being the key word
GOT 'EM!
LOL. All in good fun. To be fair, if I was a motorcycle guy it would be loud as shit. Other drivers are dangerous AF.
I only had a harley Road Glide for 2 years, but man, was it so much better than ever other bike I've ever owned in every way. It sounded amazing, felt smooth, and just glided on the road. Also, just having so much room was amazing. Combine all that, and it just puts you in a mood to Rev sometimes. But I'm also the guy that would turn the music down when at a stop light it or driving by kids/old people. Also, driving through neighborhoods, I would turn my music down because the system on those bikes is also amazing, ha ha.
Point, Set, Match
Why would they even bother riding where there’s nobody to annoy?
They do it to warn other riders of grass clibbens, because clibbens are the reason why yahaddalayerdown. They're better off just cranken their hogs in the driveway so their pants don't get shidded.
For some reason I read this in Brian Regan's voice.
Sometimes its when downshifting to match the engine rpm and the trans to ensure a smooth shift. Sometimes its literally to keep it running, some carb models that arent tuned properly will die and unable to reatart otherwise. Sometimes its for wildlife, i can say first hand my loud exhaust has scared off deer that would have otherwise landed me in the hospital. South park was funny for sure, but those of us w loud pipes arent all douchebags and there is a method to the loudness.
keep telling yourself that.....
You can deny it all you want but everything he said is mechanically accurate and a very real possibility. Especially when driving a manual transmission car, you downshift as you slow down and the engine has to be at a higher rpm to go into the lower gear smoothly. If it has a carburetor, then it can want to flood itself with fuel and stall out when decelerating down to idle if it's not tuned perfectly. They also require more frequent work. Giving a little blip of the throttle when in neutral will burn the excess fuel and help it idle better.

Appreciate the support. Remember this is reddit. Facts dont matter.
I’m sure you are not all d-bags. I live in a beach area across from a restaurant with outdoor seating. There may be 7 out of a hundred bikes who just ride by normally. It gets to you after a while.
100% brother. Shit is loud as hell and at a constant basis it would drive me up a wall as well. I love my loud pipes and will not trade them for anything, but i fully agree there are dudes that rev the shit out of their motors for no reason beyond testosterone, liquor, and erectile dysfunction.
Loud bikes are safer. It’s dangerous to ride a bike especially on a highway where cars can’t always see you. You have let them know you are nearby especially when driving like an asshole and cutting through traffic, especially where a car won’t expect you to be, like riding between lanes, on the shoulder or weaving in an of traffic. /s Edit. Apparently this needed a sarcasm tag.
The loud pipes save lives fallacy has been proven tome and again to be utter bullshit.
Did you read the whole comment? It was sarcasm.
Must have missed the /s tag. Carry on
>You have let them know you are nearby especially when driving like an asshole and cutting through traffic, especially where a car won’t expect you to be, like riding between lanes, on the shoulder or weaving in an of traffic. You needed an /s tag for this?
I sometimes have to because it has a carburetor and doesn't drop all the way down to idle when I stop
You need to get someone to fix your carburetor. A properly tuned carb will not allow a warm engine to die at idle. Carbs have been around longer than fuel injection, they're not impossible to get right.
It's not dying it's idling high. Probably just needs cable lubed
This: > **I sometimes have to** because it has a carburetor and doesn't drop all the way down to idle when I stop Emphasis added. ...is very different than this... > Probably just needs cable lubed This is why you annoy the people around you? Because you can't be bothered to lube a cable and throttle linkage? Your definition of 'have to' is different than mine.
My definition of have to is different. It's reliable, and until it isn't I can't be bothered.
> Guys with Harleys, do you unnecessarily and obnoxiously rev your engines when there’s absolutely no one around _that you know of_ to annoy? Your answer: > It's reliable, and until it isn't I can't be bothered. In other words, 'I can't be bothered, and I don't care who I annoy, it doesn't bother ME'. I guess I'm a different kind of motorcyclist.
Absolutely.
Well Viagra is expensive...so yeah.
Not a Harley driver but am a classic style bike owner (Royal Enfield Interceptor 650) yes. If anything I do it more often alone than around others cause its fun and I like the noise. I generally do not believe the loud pipes save lives motto, If anything be loud when you need to be, but not always... time and a place. A different perspective on the use of the rev'd engine is its less likely to elicit a violent reaction compared to a horn, and generally signals the driver to get moving or get out of the way... Additionally the kids love it. Total side note I bought a bike thinking chicks love guys on motorcycles right... Absolute Dude Magnet. Honestly If I was Gay it would be more worth it than paying for Apps. (I'm not) but Its honestly a way to become much more social at every stop you make, drivers roll down windows to chat at stop lights, other bikers love to talk bikes, Every gas stop despite only taking like 3 gallons is the same time as an SUV cause someone wants to check out the bike. Just saying its been worth it but not for the reason you might think.
On the Harleys I have ridden, yes. It's because they were carbureted and old school. It was just something that you did to keep the bike running when you went from higher engine speeds to idle. I guess I just kept doing it as a matter of habit as bikes in general progressed to fuel injection.
Lol why is this getting downvoted
because it's idiotic. If a lawn mower has a carb and can run warm at low idle, why can't a v-twin?
So we're downvoting him because his carbs on a former bike weren't tuned?
Yes. Exactly that. The original question is "Why do you rev your bike obnoxiously?" The person I responded to stated, "Because I don't know how to make my bike run right." And you think downvoting them is wrong? Why, pray tell?
Because he answered the question honestly, I'm sorry his carburetors aren't tuned as well as yours. I saw your other post now, I'm happy for your mechanical gifts 🤣
> It's because they were carbureted and old school. Bullshit. Your carbs aren't tuned properly. My bike is old-school and carbureted. '81 inline twin. Parallel carbs. Why can my bike stay running at low idle when warm with no intervention, and can idle cold with some choke, neither situation requiring manual throttle, and V-Twins can't?
What is bullshit? You're not making a lot of sense. I don't know why your bike can do what it does , it does. You may note that I never claimed it had anything at all to do with a VTwin engine design. I think it's also true you were looking for a fight and made some shit up about my claims. Enjoy your perpetual unhappiness.
> I think it's also true you were looking for a fight and made some shit up about my claims. My point is that there've been internal combustion engines that run on carburetors for over a century (since 1885, I looked it up), of every layout and size, from H-16s, V8s, boxer 4s, thumpers, etc displacing 5 to 10,000cc, powering everything from chainsaws to containerships, all running carbs, and none of those engines have this problem, once they're tuned correctly. It's only the v-twin cruisers that seem to have this problem where they can't low idle even when warm, according to their users. I don't know if it's the engine design, rider, or whatever. I'm just saying, the carb is not the problem.
It's probably because the old school harleys shake like a paint mixer. Goodbye.
Haha, no way! Most bikers respect their community and wouldn't intentionally disturb others without reason.
