I have a 62cc engine on the back of a scooter frame made for an unmodified 41.5 cc engine. The engine is putting out a ton of power for what it is, 8hp maybe from 5 stock, and i sheared two of the 4 engine mount bolts right off. Im going to tap out the threads to accept a bigger diameter bolt, use an engine mount with springs and rubber grommets to reduce engine vibration, and id like to work a tuning fork into the equation. I remember some hammer company put a tuning fork into their handles to stop the impact tremmors when the hammer would strike a surface. Im thinking if i put a tuning fork on or near the engine perhaps attached to the frame, this will help my cause. True assumption? if so what frequency tuning fork do i need. My engine revs right now to 12,500 rpm, but may soon go to 20k. As i said, about 7-9 hp. engine mounted to the frame via 4 bolts only.
