also you might want to check all the track clips to make sure they are all there i had a bunch of the clips with guides break off and it vibrated like hell but i also had a loose motor mount. replace the track and tightened the mount and no more vibration

My wife said its me or my sleds... Im sure gonna miss her
to check this, remove the belt and SLOWLY accelerate up to normal cruising rpm, if all feels smooth check your drive train, if you feel the vibration its in the engine.
