Title: EVO 1340 36K Miles Vibration at 2000 RPM all Gears
Post by: Blue99FXR3 on August 16, 2015, 12:07:55 PM

Anybody experience a rotational vibration at 2000 rpm out of nowhere in all gears.  Just happened yesterday following our usual weekend ride on A1A about a mile from return to the Hacienda. 

Took it out solo for a shake down this am, same deal. No loose wheels - Tires are great - drive belt is 1000 miles and perfect - suspect is the V Twin Powerplant or maybe trans.

Any such experience / ideas welcomed ...   FE

Rubber mounted powerplant?

Blue Flame FXR3 - Rubber - the EVO Harley has no difference in movement in it's mounts by revving - just a way stronger rotational vibration at 2000 rpm.  I will check the mounts however, could be a motor on frame disturbance ...   Thanx !  FE

Check Engine mounts, check handlebar mounts, check compensator.

Check the easy things 1st. Primary chain is probably loose and needs adjustment
