2005 Yamaha blaster starts just fine runs good but when I get on it the whole four-wheeler vibrates like crazy if I stay on it the vibration will go away tell I let of the gas then it will vibrate like crazy again.

Are the motor mounts tight? Maybe a counter balancer bearing going bad? Where is most of the vibration felt? In the bars, etc..

Got to looking and there is a nut missing from a bolt that connects the head to the rest of the motor. And most vibration is felt in the handle bars, and sometimes in the back of the seat.

I would be looking into the missing bolt. There is gonna be some vibration in the bars, and everywhere overall. I would start checking every nut and bolt. Wheel bearings, swing arm bearings and such. Is this a new bike for you?

Doubt this would be the culprit but the rubbers are still in the fins of the cylinder correct ?

No I've had it for awhile rebuild the motor at least 3 times just gonna get it fixed and get reid of it.

Make sure the gear for the counterbalance shaft and the primary gear are timed correctly.
