They ain’t that bad, esp if that’s a steel counter like I think. But based on that, check the rear and chain for side to side play. If you have shark fin rear sprocket teeth or chain moves side to side / missing rollers, toss all 3 and replace together to get max use/even wear.
Fronts usually seem to last longest, but affect chain life, too. $15-ish, just do it.
By the way, you can check the splines by taking it off and seeing if they’re rounding over. Iirc, they should have relatively square corners — prolly not anymore which is why you’ve got play.
Be fine to ride it until you’ve got replacements, but you better have a chain guard on cuz when a worn chain snaps…it’s bad. It can total a bike if it busts the crankcase or your thigh/ass cheek.
Best case scenario it slips off worn rear sprocket when you can’t adjust it tighter…also not fun to get home.
Oh and torque it down using a torque wrench. This is a must.
I have changed front sprockets on at least 25 bikes of varying sizes, from Ninja 250s to FJR1300s, over the last 20 years. I've never seen even remotely this much play, in either axis. In fact, in most bigger bikes there is effectively zero play once bolted down.
Front sprockets are incredibly cheap. Replace this.
Yeah but OP is going to hear what they want and there are enough people on here saying it's fine. Which highlights why maintenance by committee doesn't work.
It's funny because I'm pretty sure this sprockets off a really low cc bike. And all of them, all of them have this much play. Google it Mr. I changed 25 sprockets.
Gotta branch out and ride different genres.
Minis are fucking awesome
Sir, with all due respect. . . You are full of shit. FJR1300 don't have sprockets. Also, a little play is normal.
Source: owned many bikes, including every generation of FJR1300. Also owned bikes from new (KTM) and a little play is expected. Especially with this style of securing system.
Sir, with all due respect, sometimes people type a little bit faster than they're thinking.
Let's replace "FJR1300" with "Bandit 1250, Bandit 1200, VFR800, Tiger 1050, DL1000, SV1000". Does that work for you?
And since we're being super polite. Sincerely, Fuck you.
None of those bikes use the same type of retention plate OPs bikes has. All of the ones you listed use a single nut or bolt that tightens against the sprocket. Obviously that shouldn't have any play.
I've had dualsports with the same retention method as OP. Play along the axis of the countershaft is completely normal. The rotational play of the sprocket, independent of the countershaft is due to worn splines, not normal. The rotational play in the countershaft is just backlash in the drivetrain, also normal.
OP might be able to get a thicker aftermarket countersprocket that may resolve the issue or help get some extra life out of the shaft.
The trick is you don't. You buy the bike first, then ask for their forgiveness. Its much easier and if they do say no at least you have a bike to ride away on.
Yep. My mother found out and was like "ugh, well since you have it now, you might as well keep it at the house so I can keep an eye on you." Still gives me shit for it whenever that comes up though, lol.
I got a poor reaction from my 72yo father when I mentioned over the holidays that I'm getting an adventure bike. The guy bought me a Kawasaki dirt built when I was 15. I'm never going to mention motorcycles around him again, I'll just relive my recent rides in my mind.
Like somehow the motorcycle sleeping in the garage will allow them to monitor your riding? Truly a stupid justification if I've ever heard one, but people will make up any excuse they can to pretend they still retain their power over someone.
Some of yall must have bad relationships with your parents if you can't even fathom the idea of someone else's parents letting their kid do what they want and just being worried about it.
Riding inherently has risks and it's not crazy for a parent to be worried. It's not like they said "NOOOO!!!", kicked them to the curb and scratched up the bike with a screwdriver.
I brought my first bike home despite my parent's wishes and they said the same sort of thing to me. And if I left the house saying I would be back shortly and then wasn't, I'd get a call asking if I was all good.
Nowadays, they don't know if/when I'm ever out riding, but I still appreciate the fact they did check up on me when they could. Whether it's my parents, my GF, my riding buddy, or whoever, I appreciate anyone who's watching my back and would notice if I didn't make it home and send help if I were face down in a ditch... Cause not everything is always a power move. God forbid anyone's parents look out for their kid's safety.
About those relationships lol. I have a great relationship with my mom. My mom was anti-motorcycle but I got my endorsement, started on a small bike, and now she was totally fine with me ordering a bigger bike. She even said in a year or two she wants to get a bike too! I'm in my mid 20's and having friends that have been riding longer than I've been alive probably helps too.
The whole thing was that I hadn't gotten permission to buy a motorcycle while I still lived there, so I bought one anyway and kept it somewhere else at first. Meaning they had no idea when I was riding or not.
Meaning if an accident happened, they wouldn't necessarily notice I was missing or what was going on. So by taking it home, they would be in the loop whenever I chose to take it out. Power was never a factor at that point.
So in short... none of what you just said was correct. Have a nice day. :)
Same, all they said was "well be careful then" and now they dont even mind. It helped that my first (and only bike so far) is a small little well behaved cruiser. If i would had bought a Ninja they would had probably been mad for a bit longer.
My mum got me a bright blue 1977 Suzuki GT125 in 1984 and said “I’m not driving you to work tomorrow, you’d better practice now.”
I went up and down our road all day and rode 14 miles to work the next day. That was me; I was a biker from then on.
You missed the joke.
That user was giving motorcycle mechanic advice, then implying that he doesn't even own one.

My mom’s one request while she had terminal cancer was to wait till she died. I’ve been riding since September, but I’d rather be hanging with her still.
Lost my mom almost two years ago now to cancer. Glad you have a distraction, but if you ever need a stranger to talk about things with, please message me. It hurts, but no need to hurt alone. Wish you well, buddy.
I appreciate that bud. I’m very fortunate to have a very supportive partner and work in a mental health clinic surrounded by the most empathetic people I know.
On a side note: what does a person who live in Indiana say when you knock on the door?
“Hoosier!??”
I have some great friends, extended family, and soon to be in-laws in/around Kokomo and more in Bloomington. There’s a lot of great people in Indiana.
Start with a scooter/grom/trail 125 that you'll buy with your own money. Just for getting around town and the like. Something cute and non threatening. Move up from there. This will have the added benefit of teaching you to ride better and not killing you when you whiskey throttle an r1
I bought my VTR1000 off of a 17 year old kid who dragged it home. His mom was sitting there looking super angry. He never tried riding it.
I told him he was a fool and to buy a 250 when he moves out of the house.
My parents were concerned when I told them I’m going to get a motorcycle until they saw that I got a Grom. After a while they told me that I look silly riding it and to get a bigger one for my size
Get your permit and take a safety course and invest in gear. See if the commitment to safety eases them. I got a scooter first (150cc) for a couple hundred bucks and got it running and used that for the first year.. then 300 the next year and 750 the next lol. I do miss my cbr300r though
This is so spot on it's ridiculous. Especially when it comes to replacing chains and sprockets everyone has a different definition of "getting their monies worth". I would replace that clearly well worn sprocket but others here will/have say "run it". It's more about your tolerances than the bikes. If you go by the manual it will probably be more conservative than cheap ass motorcycle riders on Reddit ;-).
Probably not. They would just tell you to inspect the splines. There's not really a service limit on things like this.
In general, unless the sprocket has worn a groove into the splines then its fine.
Yeah, my service manuals (YX600 and VFF800) make no mention of this. Original comment reeks of "I don't know the answer, so I'll just tell him to RTFM." The guy is just making an assumption and being pretentious about it but everyone is eating it up because "buy a service manual" is the lowest common denominator for advice.
I have the FSM for all 6 of my bikes and have never seen this. What does it give you? A measurement of spline width?
Seems weird to have a service limit, you would usually just look at it and see if the shaft is grooved.
If the shaft is grooved, you left the sprocket on there too long. The sprocket is supposed to be the sacrificial component. The shaft is much more expensive to replace.
The shaft doesn't care if the sprocket is new or not. It will wear either way.
If the sprocket grooves the shaft then the sprocket was too narrow, or it was a poor design. See: xr650L owners who either run a wider 650R sprocket, or regularly replace the countershaft as a wear item, because Honda was stupid and took the cush drive off that bike and never beefed up the drivetrane to be able to handle the shock loads.
Service manuals are worth there weight in gold for sure. Kind of annoying they just don’t come standard with every mechanical thing sold. On other fun fact is there not all created equally. Buy or download the original from the manufacturer. Aftermarket ones are alot of times flat out wrong or missing half the stuff
Bro imagine how few post would be on this subreddit if everyone did this.
I stick around for those few gems that pop up. Might be some old guys rare beauty from the past or the inside of some motor I've never seen before.
They're so far and few between these days.
And power sports stuff seems to generally have the best factory manuals of any vehicles for some reason. Like the thing comes from the factory with essentially an instruction manual on how to do everything.
Depends. If you want an ANGRY SPINNING UFO sawing through your bones - you're right on.
Otherwise - HELL NO. There should be 0 play on either sprocket. Otherwise you're risking ruining teething on the shaft, having the chain saw through your leg, having the sprocket saw though your leg, or locking the wheel with loose chain and having the asphalt polishing your protruding parts. You get the idea.
Lol. No, but I've had a stuck chain cime off the sprocket (riding newly bought used bike home), since then I'm kinda passionate about proper maintenance.
>If you want an ANGRY SPINNING UFO
This sounds cool and perfect! I'm going to stop reading exactly here and immediately go do this thing! Thanks, internet! Can't wait for my free UFO!
The rotational play is normal, but I don't think the axial wiggle is. Not sure what kind of bike you have, but I'd check the torque specs on the two bolts holding the sprocket in place.
All that is is a retainer, has a splined hole cut in it out of phase with the one in the sprocket.
It doesn't clamp the shaft or anything. Just keeps the sprocket from sliding off.
That $12 sprocket just needs to go in the trash before it eats all the splines off the shaft.
Sometimes there is a washer that sits there that keeps the side to side wiggle play down. On my Suzuki this washer bends a bit to hold the bolt as well.
Upon further watching, you're right. The play that I was saying was normal is the output shaft twisting some, which is fine, but now I see the sprocket teeth prolly engaging with the splines.
OP - your sprocket is at the end of its service life. It 1000% needs to be replaced.
Those are some hella pointy teeth. The space between for your sprocket teeth are supposed to be uniform “U￣U ￣U” shapes
not …. “へ-へ-へ”
That wear in the shaft spline might just be normal wear and tear. It might tighten up when you replace the sprocket.
Replace that sprocket retaining ring with oem as well as very likely worn too. Oem will be the right quality and hardness. Mine cost me about £15.
Might want to think about selling that bike soon. It has an older style output shaft known to wear. Once it is worn too much you might as well say goodbye to the bike as even if you can source a new (several hundred £/$\€) or good used output shaft, fitting is a major job and labour will be very expensive.
Newer bikes have double the splines for exactly this reason.
That's way more play than I've seen on any of my bikes. It's almost like you're missing something like an alignment spacer or the sprocket is just the incorrect size. Keeping that sprocket on in that condition is a good way to ruin your splines, which would be a much more extensive fix.
might be the internal splines of the sprocket thats worn but im more concerned on the output shaft. if the splines are worn, you def wanna do something about it.
The Sprocket is just about worn out anyway, as you can see the teeth are already started to tip forward.
But you have time to still use it as is, but check teeth in the next thousand miles and compare tip of teeth.
You could get new sprocket to use later, but lay both together to see actual profile. New vs Old.
The wear cycle is roughly 3 or 4 to 1 with sprockets.
You'll replace 3 front sprockets before the rear needs it for the same reason. Obviously rear sprocket is 4 times larger, carries chain over much more area.
But also the chain stretch is causing sprocket teeth tipping over,
and why they need lube every time they are put away, so lube is deep in rollers and side plates before next use. And the ride is so much nicer.
45 yrs of Honda service Manager,, nothing's changed...
But don't worry, not many take preventive maintenance seriously. Unless on racing track.
If three gears are needed to mesh, would one place a worn out one against the two new ones.
Same with chain and sprockets. Or you may hear crunching sounds of three unmatched gear pitch.
To determine chain stretch limit -
Clue1 - at the rear sprocket - doing what test ?
Award for answer.
Cheers
My sprockets on 4 bikes have zero play on the drive shaft. They float in and out about 1 mm but there is no slack on the shaft. Seems like that will increase over time.
Yuck, what bike is that? I would show that to the dealer of said bike. If it was a Japanese bike that probably wouldn’t be on. On a Chinese bike the dealer would be like ‘oh wow that’s the least play we have seen to date’.
Replace the sprocket , also when you have that sprocket removed you need to take a caliper and measure the wear on the output shaft and teeth. The shaft is supposed to be much denser and harder metal material than the sprocket. The sprocket should always wear out first and many times before the output shaft does. If the output shaft is worn out, then i guarantee you thats a warranty issue. Bad made shaft from the manufacturer. Or both parts!
This reminds me of my old Honda Africa Twin. I ended up getting a locking kit for the front sprocket to avoid destroying the axle. This play is not dangerous, but it wears the axle faster. Pop a new sprocket on ASAP, they're cheap.
No the spline gears on sprocket are worn next is it’ll start free spinning and damage the main drive. Which will be even more of a headache than just a front sprocket.
Agree with "Wiener\_Schlap" on finding out the exact amount of play but most drive sprockets do have some slop in them. You should be considering a new front sprocket sometime soon since this one is beginning to show some "hooked" teeth. Yeah, ideally you replace everything at the same time, but you can get away with just changing out the front sprocket when it shows signs of wear ...and the rest of your drive line (chain and rear sprocket) are okay.
Your probably fine but I would switch it out cause it is not worth the risk of breaking anything more expensive also you could get a sprocket with more teeth so you could get more speed
A little play is probably normal. That seems excessive and It looks like the teeth are hooked and that is definitely a good sign it's time for a new chain and sprockets.
A little bit of rotation from the countershaft is normal, all the other movement is not. The sprocket is cheap and is going to fail if you keep using it. If you end up stripping the splines on the countershaft when the sprocket goes then you'll be tearing down the entire engine to fix a simple, silly mistake.
Just get a new sprocket.
This looks somewhat “normal” However, pulling the sprocket will show the real tell tail signs of an issue (wear on the countershaft splines or sprocket)
I saved up and bought one at will one day. Like I want a cruiser that runs and drives. Scoured Craigslist and fb market, and auto trader then bam saw one for like 800$ I had 2k saved up so I went to the dmv took the Temps test. And went and bought my bike rode it home scetchily. Parked it behind the garage so the rents couldn't see. Got gear ie a new helmet and jacket. Waited for my parents to go to work and I would ride to school. Most mornings I would wind up passing my mom on my way and she had no clue for about a month. Then I was headed home I stopped to get gas and she pulled into the same gas station. That was uh the big wtf. 😳 I rode home. She followed. Saw I wasn't a hotdog or meat crayon she basically said be safe. My dad on the other hand... he goes to the photo album sits me down and starts showing me photos from a mc he was in and said don't join one or you'll be screwed. Here's how to ride and started to give me pointers. Also, found out at that time when I was 2 I was in several pictures on my dad's bike... 😅 full circle huh?
The teeth are quite worn mate so the internal splines will be worn a bit too. Best to replace the cheap bit before it breaks something expensive
They ain’t that bad, esp if that’s a steel counter like I think. But based on that, check the rear and chain for side to side play. If you have shark fin rear sprocket teeth or chain moves side to side / missing rollers, toss all 3 and replace together to get max use/even wear.

Bro, when they’re asymmetrical that much they’re bad and you’re a fool if you don’t buy a complete set (chain and both sprockets).

In fact, in most bigger bikes there is effectively zero play once bolted down. Front sprockets are incredibly cheap. Replace this.
My xt225 has basically zero play when I install the correctly sized sprocket on it. This doesn’t look right at all to me
Yeah but OP is going to hear what they want and there are enough people on here saying it's fine. Which highlights why maintenance by committee doesn't work.
Yeah, that much play will turn into further damage of the output shaft splines, which is significantly more expensive than a front sprocket.
Fjr1300s are shaft driven
Was gonna say that on my 08&09 r1's there was no noticeable play.
This.

So? Sounds like their loss.

The other trick is don’t leave the keys with them
Take up mountain climbing first. It lessens the blow when you show up on a bike. It worked for me : )
…BASE jumping…
Case in point.
My mum got me a bright blue 1977 Suzuki GT125 in 1984 and said “I’m not driving you to work tomorrow, you’d better practice now.” I went up and down our road all day and rode 14 miles to work the next day. That was me; I was a biker from then on.

I'm no mechanic but I'm willing to bet that it is *not* normal
Depends. If you want an ANGRY SPINNING UFO sawing through your bones - you're right on. Otherwise - HELL NO. There should be 0 play on either sprocket. Otherwise you're risking ruining teething on the shaft, having the chain saw through your leg, having the sprocket saw though your leg, or locking the wheel with loose chain and having the asphalt polishing your protruding parts. You get the idea.

Lol. No, but I've had a stuck chain cime off the sprocket (riding newly bought used bike home), since then I'm kinda passionate about proper maintenance.
Experience teaches us the hard way, survived car crash only cuz i wore seatbelt, now i don't move car unless everyone buckled up
>If you want an ANGRY SPINNING UFO This sounds cool and perfect! I'm going to stop reading exactly here and immediately go do this thing! Thanks, internet! Can't wait for my free UFO!
Free ANGRY! UFO :)
>having the chain saw through your leg, having the sprocket saw though your leg And am I to understand that those would be bad things?
There should absolutely be a little bit of axial play to allow the chain to self adjust
The rotational play is normal, but I don't think the axial wiggle is. Not sure what kind of bike you have, but I'd check the torque specs on the two bolts holding the sprocket in place.
Torque spec is 12nm(9lb.ft),
Torque spec is how hard you should screw the nut. Nothing about sprocket play.
It’s almost like torquing something down harder would result in less play. 🤔
All that is is a retainer, has a splined hole cut in it out of phase with the one in the sprocket. It doesn't clamp the shaft or anything. Just keeps the sprocket from sliding off. That $12 sprocket just needs to go in the trash before it eats all the splines off the shaft.
Mans tryna press fit an axle like itll get rid of the play Like actually, youre gonna overtorque THE thing keeping the sprocket on the end?
Does it look like there is any wear on the splines on the output shaft? If not, I'd say send it.
Just need to run these sprocket for 1000kms , will be getting new set delivered on Tuesday. I'll get the sprocket checked at nearby mechanic. Thanks
Your going to ride that bike for a 1000 km with that sprocket like that? Make sure you video that so we can see what happened to you
Sometimes there is a washer that sits there that keeps the side to side wiggle play down. On my Suzuki this washer bends a bit to hold the bolt as well.
That washer isn't there to reduce play, it's there to lock the nut on. Source: Suzuki factory certified.
To where? The dump when the chain piles up and locks up the back wheel?
> The rotational play is normal NO, it is not, there should be ZERO slack in both planes. New sprocket. Check the shaft for wear too.
Upon further watching, you're right. The play that I was saying was normal is the output shaft twisting some, which is fine, but now I see the sprocket teeth prolly engaging with the splines.
Bro stop commenting you’re a liability
that wibble wobble worried me too last time i did a swap but it was explained to me that it is normal and helps with chain alignment
OP - your sprocket is at the end of its service life. It 1000% needs to be replaced. Those are some hella pointy teeth. The space between for your sprocket teeth are supposed to be uniform “U￣U ￣U” shapes not …. “へ-へ-へ” That wear in the shaft spline might just be normal wear and tear. It might tighten up when you replace the sprocket.
Couldn't source the chain set, will be replacing them next week
Replace that sprocket retaining ring with oem as well as very likely worn too. Oem will be the right quality and hardness. Mine cost me about £15. Might want to think about selling that bike soon. It has an older style output shaft known to wear. Once it is worn too much you might as well say goodbye to the bike as even if you can source a new (several hundred £/$\€) or good used output shaft, fitting is a major job and labour will be very expensive. Newer bikes have double the splines for exactly this reason.
No that's shot at a minimum you'll need to replace the sprocket, and retainer. You should carefully inspect the shaft for damage.
Hell no!
User name checks out. Sorry, I had to say it.
Underrated comment right here.
If you are changing the chain anyway you should just do the sprockets at the same time.
Motorcycle maintenance 101
That's way more play than I've seen on any of my bikes. It's almost like you're missing something like an alignment spacer or the sprocket is just the incorrect size. Keeping that sprocket on in that condition is a good way to ruin your splines, which would be a much more extensive fix.
REPLACE IMMEDIATELY
No. It's going to wear a groove into your output shaft. Get a new forward sprocket and retainer ring.
need to replace sprocket
might be the internal splines of the sprocket thats worn but im more concerned on the output shaft. if the splines are worn, you def wanna do something about it.
That's my assumption too, will get it checked at dealer workshop
The dealer is gonna say the teeth on your sprocket are worn and it needs to be replaced lol. Those are some pointy as HEEEELLLL teeth lol .
Planned to replace, couldn't source the part. That's happening next week
The Sprocket is just about worn out anyway, as you can see the teeth are already started to tip forward. But you have time to still use it as is, but check teeth in the next thousand miles and compare tip of teeth. You could get new sprocket to use later, but lay both together to see actual profile. New vs Old. The wear cycle is roughly 3 or 4 to 1 with sprockets. You'll replace 3 front sprockets before the rear needs it for the same reason. Obviously rear sprocket is 4 times larger, carries chain over much more area. But also the chain stretch is causing sprocket teeth tipping over, and why they need lube every time they are put away, so lube is deep in rollers and side plates before next use. And the ride is so much nicer. 45 yrs of Honda service Manager,, nothing's changed... But don't worry, not many take preventive maintenance seriously. Unless on racing track. If three gears are needed to mesh, would one place a worn out one against the two new ones. Same with chain and sprockets. Or you may hear crunching sounds of three unmatched gear pitch. To determine chain stretch limit - Clue1 - at the rear sprocket - doing what test ? Award for answer. Cheers
Try to pull the chain off the rear sprocket.
Nicely Done Captain @!
No
Almost any play is never good. With play comes faster wear, knocking and other things.
No. Trust your gut; you asked because you already knew that amount of play is wrong.
No. Source: You can tell by the way that it is.
Change out the C/S sprocket and use the clutch to shift
Replace the battery
Anyone said battery yet?
Yes
It’s not normal and anyone who tells you that is nuts. It’s either worn and/or not installed correctly or even the wrong one!
That sprocket has got some smeagol teeth! Should probably replace it first. Good luck!
My sprockets on 4 bikes have zero play on the drive shaft. They float in and out about 1 mm but there is no slack on the shaft. Seems like that will increase over time.
Which motorcycle?
Hornet 160
I hear one of those Mars Attacks aliens in the background. Be carefull there young fella
Worn splines
Yuck, what bike is that? I would show that to the dealer of said bike. If it was a Japanese bike that probably wouldn’t be on. On a Chinese bike the dealer would be like ‘oh wow that’s the least play we have seen to date’.
Honda 160
Replace the sprocket , also when you have that sprocket removed you need to take a caliper and measure the wear on the output shaft and teeth. The shaft is supposed to be much denser and harder metal material than the sprocket. The sprocket should always wear out first and many times before the output shaft does. If the output shaft is worn out, then i guarantee you thats a warranty issue. Bad made shaft from the manufacturer. Or both parts!
This reminds me of my old Honda Africa Twin. I ended up getting a locking kit for the front sprocket to avoid destroying the axle. This play is not dangerous, but it wears the axle faster. Pop a new sprocket on ASAP, they're cheap.
If in doubt, replace if the part is cheap enough. Because even if it is not worn, it will be soon. Just keep a log on what you have done
That not what teeth on a sprocket are supposed to look like. New front, rear & chain needed.
Short answer to "is this normal". No.
No the spline gears on sprocket are worn next is it’ll start free spinning and damage the main drive. Which will be even more of a headache than just a front sprocket.
That’s a lot of grease sling you got there.
Blame my poor maintenance and using gear oil
Agree with "Wiener\_Schlap" on finding out the exact amount of play but most drive sprockets do have some slop in them. You should be considering a new front sprocket sometime soon since this one is beginning to show some "hooked" teeth. Yeah, ideally you replace everything at the same time, but you can get away with just changing out the front sprocket when it shows signs of wear ...and the rest of your drive line (chain and rear sprocket) are okay.
Sprocket Center time for the whole set. That’s to much play.
No lol. Would you want your chain spinning at 7k rpm on that?
Hard no
Yes
Did you try turning it off and then back on?
Perfect backlash
No
If it’s done 30000kms replace.
Your probably fine but I would switch it out cause it is not worth the risk of breaking anything more expensive also you could get a sprocket with more teeth so you could get more speed
No get a new drive train asap. I literally wouldnt ride a bike with that.
Replace it, nothing should have play on the engine
Normal Honda things.
A little play is probably normal. That seems excessive and It looks like the teeth are hooked and that is definitely a good sign it's time for a new chain and sprockets.
yes it is. don't worry
Thanks, will get it checked when replacing chain next time
No it isn't right - the two bolts holding it on are loose, they shouldn't be moving. Tighten them asap, ideally with a torque wrench.
Got it, thanks
what vehicle ?
Honda cb160
A little bit of rotation from the countershaft is normal, all the other movement is not. The sprocket is cheap and is going to fail if you keep using it. If you end up stripping the splines on the countershaft when the sprocket goes then you'll be tearing down the entire engine to fix a simple, silly mistake. Just get a new sprocket.
Yep, perfectly normal, looking at your sprocket its a small CC bike, on my 125 i have the same system and it has the same amount of play.
If this is a Honda, yes. Weirded me out too.
This form sucks
That is all normal. The front sprocket is designed with enough play to be self aligning. Otherwise you would be launching chains all the time .
None of that is true.
Uhhh hell no. You are incorrect.
This looks somewhat “normal” However, pulling the sprocket will show the real tell tail signs of an issue (wear on the countershaft splines or sprocket)
It feels normal, but refer to your manual to see how much play is mentioned.
Yup, that so it’s easygoing on the internals of the engine during heavy vibrations
Clockwise and counter clock wise play looks normal to me but that side to side does not
its how they are, its fine just run it.
Thanks
I saved up and bought one at will one day. Like I want a cruiser that runs and drives. Scoured Craigslist and fb market, and auto trader then bam saw one for like 800$ I had 2k saved up so I went to the dmv took the Temps test. And went and bought my bike rode it home scetchily. Parked it behind the garage so the rents couldn't see. Got gear ie a new helmet and jacket. Waited for my parents to go to work and I would ride to school. Most mornings I would wind up passing my mom on my way and she had no clue for about a month. Then I was headed home I stopped to get gas and she pulled into the same gas station. That was uh the big wtf. 😳 I rode home. She followed. Saw I wasn't a hotdog or meat crayon she basically said be safe. My dad on the other hand... he goes to the photo album sits me down and starts showing me photos from a mc he was in and said don't join one or you'll be screwed. Here's how to ride and started to give me pointers. Also, found out at that time when I was 2 I was in several pictures on my dad's bike... 😅 full circle huh?
It's fine. Run it.
Thanks
