I recently Purchased a 05 roadking thats motor was upgraded to the 95. the motor seems to shake too much. what can i do to stop this?

 

Check the front motor mount and upper stabilizer under gas tank

 

What engine revs are you talking about? My experience of a new TC88 is that the darned thing was not very smooth below about 2,800rpm, but magically smoothed out above that. If you are riding it below that level you may well find it isn't very smooth.

If the front rubber engine mount is shot that will cause worst vibration. The upper stabilizer shouldn't affect vibration. To check visually the plate attached to the motor should not touch the top of the rubber and you should be able to see a sleeve between the two. When the seal fails it allows the plate to drop onto the rubber, so there is no gap.
