Default Re: Engine vibrations, not from mounting

Does it vibrate all the time or at a certain rpm? A lot of these engines hit a rpm range that give a lot of vibration, on one of my bikes its at 28 to 29 mph. On another it was 25. The type of tires help also, I changed from a 2.125 on the rear to a 1.95 and the vibration increased a good bit so I'm going back to the 2.125.
Your results may not be the same,Greg
