QUESTION: Thanks Mike
We replaced the Kuryaken air filter with a diffrent one (for cosmetic reasons) we also replaced the back wheel bearings and re did the front head bearings on the steering it seems that the vibe is not road or wheel related as i said when I pull in the clutch and coast along the vibration gooes, i have just machined out of Brass a 250g weight and installed this into the handlebar ends as well with moderate responce but it has helpd reduce the handle bar vibration.

AnswerIf you are getting that much vibration and you have check the drivetrain as well as the frame, then it seems to be coming from the motor. If your motor has enought vibration to put your feet to sleep and it just started, then your flywheels might have come out of balance. that is the only thing in your motor that is balanced
Good luck and happy riding
Mike
