Jimmy I also own an FLD, thus far I haven't had this vibration problem. From some other forums even our switchback owners forum this has been discussed to death. A couple of things that we have found is 1 the exhaust is part of the problem, 2 happens ar rpm range of 3000 to 3400, 3 the front motor mount needs to be shimmed, as far as the vibration felt in the hands, the riser bushings need to be changed from rubber to the poly bushings. Hope that gives you an idea of what we have come up with and also might want to check the mounting bolts for the tank. Another owner found that the steering head was loose which after he took it back to the dealer they had to change the race and bearings. So all this is possible causes but so far no real cures
