Weird Sound

I started to notice an odd sound while out riding yesterday. It really only happens, or at least I can only hear it, when in first gear first starting off. It is a sort of clunking sound that sounds like it is coming from the front sprocket area. I can't really replicate it unless on the bike and riding. It seems most noticeable when taking off, but can also be heard when accelerating from a crawl.

My chain/sprockets are worn and will be getting replaced this weekend, but don't know if that could be it.

During lunch today I put the bike on the center stand and could not replicate the sound. I got close by holding the rear brake. I checked alignment and it is okay. I also took the front sprocket cover off and checked for missing teeth or anything obvious. There was a decent amount of grease in there and what looked like metal flakes/shavings.

You see any severely kinked links? They may clunk when forced to straighten out under load.

Note...when just rolling the bike in the garage, it makes a ticking sound from the same area that sounds like the sprocket teeth and the chain meshing poorly.



Any ideas?

The chain is not kinky at all and moves very freely. I also made a mental note that playing with the chain right after riding will burn your fingers.

Only ideas are the obvious things you already checked - I would just wait until I replaced the chain/sprocket this weekend and see how it sounds before getting too concerned...

I think I have the same thing going on...It sounds like it to me, anyway. The clicking noise goes away after I spray some lube on the chain. I'd really like to figure out what is ultimately causing it to make the noise, though...

I've had the same thing before and it always disappears when I replace the chain and sprockets so I think that will fix the issue. I don't know if it's just chain, or just sprockets, since I always replace both. If I had to guess I think it's the worn front sprocket.

Cool deal. I'm looking forward to getting this replaced.

You got everything mapped out for Saturday? I think Rod may join us on a return ride towards your neck of the woods or we might make a quick loop around here.

Pending weather I think I'm good. I don't have a GPS on the Superhawk so I'll just ride around town until you find me.

Rod needs to be there to get his hands dirty. I'm great at supervision.

So with three supervisors, how does work get done?

I could have my 9 month pregnant wife do the work while we watch.

+1 Iconcur, same happened to me. I think its the stretched parts in the chain slapping against the swingarm.

I also had something similar. It would do it rolling the bike or just spinning the wheel on the rear stand. It happened right after I replaced the chain. I loosened the tension a little and it got better, but didn't go away completely. It went away after I rode it a little while. I bet it goes away with a new chain and a few miles.

Fine by me. I'm not one to stand in the way of a woman doing work. If she goes into labor I'll let you know now I am CRR and defrib certified. Other than that, you're on your own. I will yell "PUSH" every once in awhile to help out. If that happens I think Jim would be a good name, boy or girl.

I can assure you it is not too tight. Maybe too loose.

Took my chain off tonight to begin prepping for replacement this weekend.

This looks awesome, doesn't it?

That's a very curvy chain you have there, Chris...

My clicky noise is back today, I think I will lube it tomorrow! If the noise indicates I need a new chain then I'm suprised...its a DID XVM530...I've only put about 17,000 on it. aren't good chains supposed to last longer than that? maybe I should try the slinky test like you did on the picture...

I meant to take a photo while the chain was still on but didn't. I could grab the very back of the chain where it goes around the rear sprocket. I could pull the Cain away from the sprocket enough to see about half a tooth or more. The chain also started going out of adjustment very quickly. Where I used to go nearly 1,000 miles between adjustments. It started getting adjusted at every clean and lube interval, then started getting out of adjustment before 500 miles. I was pretty anal about cleaning the last one, but I'll be even worse with this one.

Another thing to consider is a build-up of 'gunk' and possibly a stone stuck in said gunk under the cover of the front sprocket rubbing against the slow turning chain - there is not a lot of room under there and oil fling and road grime can collect into a great wad of black sticky gunk.

PS - 'gunk' is a Honda approved technical term for this material, however 'crud' is acceptable.

This is a dead giveaway that there is too much friction going on in the chain, BTW.

Thanks for the hint.

How did you like the curvature of my old chain? I'm guessing that isn't normal. The teeth on the sprockets are getting pretty thin too.

Just last night after a 40 mile ride, buddy and I stopped and I just happened to feel the chain, checking for looseness, etc. and it was barely warm. Definitely too much friction going on for you. (twss)

HondaJim helped me replace my chain today. All is well again.

I'm actually amazed at how much difference it made. The bike is quieter...well...as quiet as it can be with Satos on it. It's also much smoother on and off throttle. I guess the old drivetrain had so much wear in it that it just kinda slopped around.

I had to test it out by making a 130 mile loop through southern Indiana. Good ride guys. Thanks!

Twas fun.

Don't forget to log how many miles were on the bike when you changed it so you have some idea how much you got on it.

How many miles did you get on your now defunct chain, Chris?

I keep track of everything in a Vehicle Maintenance spreadsheet. It had 29,206 on it when we put the chain on yesterday.

This is a tough one to answer. I bought the bike used so...
- If it was the original chain, it had just over 29,000 miles on it
- if the previous owner had changed them before ,it had at the very least 14,500 miles on it.

I had been fighting rust on/in the chain since day one so I'm going to guess that he either had never changed the chain/sprockets, or he changed it, but wasn't good with chain maintenance.

Now that I know first hand what to look for in a failing chain, I'll change it earlier next time.

Funny, I do to

In fact, just today I was updating mine thinking...
"I wonder how many other people have one of these?"

I have a single Excel document with a tab for each vehicle.
Just today I added a column for my bike that shows me the mileage I get out of things like tires, oil changes, spark plugs, etc.

Quite handy!!

I also have all vehicles on separate tabs. I guess I could calculate mileage for wear items, but I don't. I keep track of the item, date of service, mileage, and price. I even add the original purchase info in and track my total cost of ownership.

I've always pulled the chain off the back sprocket, if it lifts about half a tooth off, means the chain is stretched too far.
I had the clunk on my old bike, was stuck links and also the front sprocket had too much movement on the countershaft, just some food for thought...

Ps.. I'm back!!!
