Got a bit of an interesting one for the crew.
Changed f/r sprockets and chain ~ 600 miles ago on my '96 Nighthawk 750. Used good quality parts ~ only had an issue crimping the master link, but clearance was equal/sufficient in the end.
The issue is that there is a cyclic noise/grind. The cycle of the sound is directly related to final drive (i.e. gear independent). It's definitely related to chain revolution based on the frequency. But the chain looks good, the sprockets look good. What am I missing?!
I'll try and get a sound bite after I finish up the clutch replacement this weekend, but the best way to describe it is that it sounds like a few links (~4-5) are grinding as that portion of chain moves through the front housing.
There doesn't seem to be much physical displacement (i.e. the bike doesn't slow/choke) as the sound is made.
Any ideas at all would be great. I am not a hardcore bike mechanic, but I understand most things.
