hey i keep hearing a noise coming from behind the front sproket. if i super loosen the chain the noise goes away, but when i tighten it the noise comes back.

kinda sounds like a roulette table spinning with the ball bouncing around.

theres plenty of oil in it. 3/4 window full.

chain is lubed


any advise?

Take the sprocket cover off and investigate the noise. How much chain slack do you have? What kind of chain lube are you using? How many miles on the chain?

i took off the sproket cover and sproket.

i have about 1 inch slack

im using Maxima chain lube.

7,800 miles on the chain.


i took the sproket off and cleaned it. there was lots of redish brown dust.

what are you thinking it could be? is there a bearing in there?

Did the problems start after you took the sprocket off or before? Also you want a little more than 1" chain slack. Better to have the chain too loose then too tight.

Clean and inspect the chain very carefully for any kinks or binds. You can use Honda's Brake/Contact Cleaner. Lube it heavily with a good quality 90W gear oil and see if the problem goes away.

soundlike the chain might have a couple of links that are binding, lube the crap out of it and make sure all the liks are loose

sound happened before i took off the sproket.

ill check the chain to see if there are any binding......

5 years later and still have the knocking sound...

Bearing on the output shaft... the tighter chain puts an uneven load on the bearing and causes that part of the race to go out of round, the balls then have a little movement and can cause some knocking, it should increase in frequency with road speed.

Would be a real pita to repair...
