Primary chain - doubt it; drivebelt - maybe but still doubtful. What do you call "excessive"? At what speed/RPMs is the vibration present? At idle all Dynas shake quite a bit.
All these things are gimmicks for people too lazy to find the real problem.Hippo, thx for the reply, have any experience with "Velva Ride" top engine links? How about Hayden M6 primary tensioners? Pipes look good, not grounding out anywhere. Have'nt looked at front mount yet, have gone through mount centering task. Bike has just 10k miles..
