crazy weird bike noise

[ozgmerih]

Hello everyone. I've been getting this strange noise from my 2023 R25 motorcycle for about 8,000 km, and it's becoming quite annoying. Either the mechanics can't figure out what it is, or they deliberately don't tell me to keep me busy. I've never skipped maintenance. I use the best Yamalube oil. I just replaced my clutch pads, oil pump, oil filter, and idler gear. I had my camshaft tensioner checked, and it appears to be working properly. The current mileage is 28000 km. I need your experience. Thanks.

Since you’ve done maintenance and key parts like the cam chain tensioner, clutch, and idler gear are fine, the noise could come from a worn or misaligned chain, transmission gears, valve or cam chain guides, or even the clutch basket. Engine or exhaust mounts might also amplify vibrations and make it louder. Recording the sound at different RPMs could help pinpoint the issue, and noting whether it happens more when idling, accelerating, or decelerating can narrow it down.
