I have a 80cc on a stretch cruiser. So bad your hands get numbs at high RPM. Has anyone ever tried to balance a flywheel.
Try switching to a smaller rear sprocket the engine won,t run as hard therefor you will have much less vibration.
I just picked up an "Upgrade Kit" on eBay from LiveFastMotors...$15 will get you a 40t sprocket, new chain, and a few other items...I'm currently using a 44t, and the entire reason I went with a smaller sprocket was to get rid of the vibrations at 25-26mph. Not planning on going much faster, but I should get a bit better gas mileage and of course lower the vibrations at that speed.HookWorm - Yes on a slow revving engine that is a good answer. I do have a 39 tooth sprocket on the Green Hornet. I like the smaller sprocket keeping the noise down also. Have fun, Dave
