It starts right up perfect runs great doesn't burn my leg I've been riding it for about 2hrs today and at the top of the gears it will throw out smoke. and also how do you do a compression check?

 

To do a compression check you obviously need to have a compression gauge, which screws in to the spark plug hole. Then turn the kill switch on so it cant start, turn the gas off also, then hold the throttle wide open and turn over the engine.
