I have an 06 ultra with a 98" motor. I had the tru trac installed last year, after some high speed wobbling experiences. I heard about the Sta Bo bushings and their heavy duty motor mount. I talked to Ken from Sta bo, and bpought the bushings and the motor mount and installed them, only to find out the vibration has, or is going to break something in the faring! i think the motor mount is WAY too solid, and the rest of the bike is getting shook apart! My radio LED quit working, and on the way home on the first real (250mile) ride, I heard something snap in the fairing. I am going to take it to the shop and either have them put a factory motor mount back on, and see what happened to the radio and fairing, and see if this helps the fix. I seen a post early this month about this, and I guess thry contacted sta bo, and they said the vibration would go away in 3000 miles. Any insight from anyone?
