    I got my new motorized bike kit put together and everything was working fine. But now im having problems with the idiling/throttle. The bike will run fine for a couple minutes, then when i try to give it gas it wants to bog down. When i stop and hold the clutch in it revs real high. I have changed the carb and throttle cable and i still have the same issue. I have also tried adjusting the idle screw. Any possible solutions or ideas to help me fix this problem?

    if it seems to smoke too much when it bogs, you may have gotten fuel in the bottom of the motor - if you keep it running this will usually clear up after a while

    otherwise, try putting choke on just a bit and see if it kills the motor - if so you're too rich and should drop the needle in the carb a bit, if choke makes it run better, you're leaking air someplace (usually intake, but could be seals or head gasket)
