Hey guys. I just bought a little Z50 with 2 motors off craigslist. The motor mounted to the Z50 is an SL70 motor, but it is missing the flywheel with the mechanical advance. The other motor is some 110cc chinese thing. should i just use the 110 motor? or would anyone be interested in trading a z50 or ct70 motor for the sl motor? compression is good everything is there except the flywheel, no rust that i can see.

Im in Escondido Ca which is near san diego.
