Default Excess Vibration

Well last weekend i came into some whoops full noise in third and the bike started to vibrate badly but i heard no bangs clangs or anything, i shut it down had a look but couldn't see any thing, i've since drained the oil and no metal, without pulling it down i don't know where to start. the motor is in a wild hp300 quad but is the same as all 300 , still has good compression but is due a piston and rings, can anyone assist it would be great.

Any loss of power?
Does it make a knocking sound when you have it idling & then give it a burst of rev's?
If not ,could just be an engine mount.

Take the stator cover off and give it a wiggle to see if the left hand main bearing has clearance.

Take the chamber off and have a look into the cylinder to check the top end.

Check that the chamber is not just loose as it can make a big rattle noise.
