I had the same problem with engine vibration take a look at your primary clutch bushings inner and outer. Had new bushings pressed in and it solved my vibration issues.
Good Luck
Was your vibration problem at idle, or was it when the clutch was engaged and you were moving? Mine seems to be bad at idle. If you lift the hood when it is warming up you can see the motor really vibrating. My Polaris triple is much smoother than it is, so I am just guessing something is not right. Who knows?
