Has anyone tried vibration dampening on the handlebars?   I don't mind the clutch side so much because I can let go and shake my hand, but the throttle side is annoying.   I was thinking putting a few inches of lead in each side to change the resonance, but thot I'd check to see if anyone has done it.   I've also heard of the vibranator gadgets and was wondering if anyone has tried them?
