My chain has been making noise most likely since the first ride of the season. I never noticed till I ran it on a short ride without earplugs or helmet. Quite noticeable.
I readjusted as per service manual (20-30mm (closer to 20mm)) with the chain at the tightest point using the side stand. After putting bike on a lift that measurement is 30mm. At its most loose point its 38-40mm.
After a spin around the block the noise is still present.
I put a dial indicator on both sprockets teeth (O.D.).
The most they’re out of round is 0.015”.
Measured the chain (321mm per 20 links max) and found no link set longer than 317.8mm. That was 50 different measurements (112 links, every other link).
The “tight” spot is always in the same place, telling me it’s the rear sprocket.
If the o.d. of the sprocket is “true” to the axel. Is it the root depth of the teeth changing?
Next question is where do ya’ll buy your sprockets from?
The chain I’m going to buy is a step up-D.I.D 525ZVM-X Nickel Super Street Chain
oh ya my chain is cleaned and lubed religously
