I just bought my best mates Buell 03 xb9r and when on idel there is a strong vibration through the bars to the point you can see the skin on your arms vibrating with in and last night while i was riding i could feel the vibration at lower speeds through my boots from the pegs i changes the front isolater last week thinking that would be the problem but seems to have done nothing the rear isolator looks in good condition just cant seem to pin point whats causing it and my mate said never used to be like that when he rode it only noticed few months ago any help on the matter would be great thank you....
