I suspect it is the mods you made to the clutch that is causing the vibration. Good luck chasing this down.Hello fellow bikers,
I'm facing a vibration problem on the bike which can be felt through the footpegs and handlebars when cruising and hard acceleration from 6000RPM to 7500RPM. The vibrations sort of feels like riding through small rocks. Vibrations are gone when clutch is pulled in. The bike is smooth when it's outside of the 6-7.5k RPM range. I know vibrations are normal for 3cyl bikes but the vibrations at this RPM range is enough to damage my phone's camera stabilization module and gives me numb limbs only after 1 hour of ride.
I've changed the clutch thinking it's broken but everything was fine when I opened it up. So I did the upgrades anyways. I've brought it to the local agent as well but the problem still persists.

I've tried lowering the CO values to 6-4-6 and the vibrations seems to be less but it's still there.
Really appreciate if anyone has any idea on what could be wrong or have any possible fixes to share.
