Our YZ85 has little if any vibration through the bars and we are running fat bars. Does it only vibrate at idle? What happens when you pull in the clutch?

I would start by tightening all the nuts and bolts. Especially the motor mounts. If that doesn't help the main, connecting rod bearings or piston/bore may be worn beyond their service limits.
