    Mcculloch Mac-15 80cc motor

    Mac 15 engine. 80cc. In good shape. Been sitting a long long time. Has great compression and spark. The motor is missing the intake and carb. This motor is still a 2 port. Pretty torquey but low reving. The 3rd port is cast in the cylinder, just needs to be machined out if you want a hot revvy...

    80cc Your thoughts?

    a fellow has offered me this "bike" which I have no interest in at all, but, the engine may be fun to put on a mini bike. It is a Yamaha 80cc with gear box. He installed a suicide shiftier and a foot clutch. What do you think about the engine on a small mini?

    Thinking about yanking the 80cc china engine

    I recently bought a used 7-8yr old Monster Joe 80cc ATV for my son. It does not have spark. What should I check/replace? It has good compression. Have an idea of yanking the engine and welding an engine mount plate on the frame and installing a clone GX200 with a Comet TAV2 - will it work???
