2003 Heritage, 40K miles. Has vibration I can feel in the bars starting around 40 mph. The faster I go, the more noticeable it gets. If I pull in the clutch the vibration is gone, which leads me to believe it is something with the drivetrain. The mirrors vibrate where it is hard to see out of them. The engine is not rubber mounted so there is no mount I can change. Maybe loose compensator or clutch basket?
