For a while at exactly 3000rpm I was getting a ringing noise, like a loose washer on a bolt. After a few hundred miles the sound moved up to 5000rpm. Doesn't change with the clutch applied/released or moving/stationary.
It sounds to be from the right side of the bike. I removed the tank and resecured everything but the noise still happens.
The oil screen didn't have any debris and the oil sample returned normal other than slightly elevated iron, which blackstone said is likely from the shared gearbox.
I have the ACCT rebuild kit coming from TOC hoping its just a stuck cam tensioner. Is there another source I could be missing?
Primary chain? But I think the noise would change ringing RPM with the engine loaded or unloaded.
