Clone motor vibrations

beachcarter

My clone motor makes everything on my cart vibrate. Mainly the rear flip seat and the brake pedal. The motor sits on 2 2" square aluminum blocks to gI've it enough lift for the cylinder head to clear the forward and reverse cables on the axles and its bolted to the cradle. Has anyone done anything to dampen the vibrations from the motor? I'm wondering if I put some sort of rubber insulator, like maybe cut a piece of old rubber truck bed mat and put it between the motor and the blocks if that would be enought to absorb most of the vibrations? Any ideas or thoughts?

I put mine on the stock mounts, so it has 4 rubber mounts under it. Its about like stock, but can vibrate a little when I gas it at slow idle. May have something to do with my head being cut too. Running it is like stock. Issue is if you bolt through and compress the rubber in there it does not absorb, the bolt is still securing it via bare metal. you could investigate CC mounts iirc they are just rubber bumpers the motor plate sits on. You could use car engine mounts somehow. You could make mounts out of hockey pucks or similar. We used to drill them and stack for truck body lifts. But you would need to secure the outside and bolt in the center, or use each side, something like that. McMasters might have something.

You can't have it move much as it will mess up the cvt shifting. Yamaha has a torque cable on the front corner that keeps the engine from moving back, as it will under torque. It only hits under power.

You can try rubber mounting but in my experience it doesnt make much of a difference. The single cylinder engines vibrate and thats pretty much the nature of the beast.
