    Ok so I have mounted an 80cc engine kit and the exhaust studs keep falling out. Would anyone recommend tapping it because I don't know what to do so please help.

    working carefully, these can be retapped a bit larger or heli-coiled for new 6x1.0 threads

    sounds like you also need the muffler hanger that used to come with most kits to support the weight of the muffler

    support the muffler.
    excess vibration is reduced with the Jaguar CDI and balancing the crank
