    Thoughts on my vibration? Any help appreciated.

    So early this season I picked up a minor vibration on my GP1200. It's only evident when the ski is in the air and I'm on the throttle. I obviously let out, but sometimes it gets a little rev going. Today it got hella worse.

    I'm thinking, either bearing, or broken motor mount. The motor mounts don't seem particularly loose, seeing as these skis are rattle monsters anyways, whats the easiest way to tell if a mount is broken?

    JUST A THOUGHT..how is the coupler on it?... under load its rubber is in a bind and running smooth, but when in the air (unloaded)its free to hunt around and the pump is bouncing back and forth off that 'play' giving you the vibration
    to test a mount ..wedge a small pipe or pry Bar under the engine and try to pull it up at the four corners inspecting it while doing this...

    Coupler damper was a thought of mine as well. I'm just wondering if anyone has had the same problem before I start tearing it apart.

    Ate two ears off the damper, but there's alot of wiggle behind the rear coupler, I'm thinking the bearing is gone as well.
