Does it vibrate alot at high rpms?
Does it sound like its starving or getting too much fuel?
Is there anything besides the kill switch hooked up to the white wire?
Can you feel if anything is binding when you ride it around without the motor running or just spinning the wheel?
Another thing to check is your main jet. Remove the bowl and unscrew the main jet and use a needle to clean it.
it vibrates a bit excessively when it hits top speed.
it does feel like its fuel starved.
nothing hooked up to the white wire.
no binding when i pedal manually.
i guess i will have to pull the carb apart and see what the problem is.
