Just pickEd up a kx125 not running for $700. It had a wire broke of the magneto. Solder it back on started first kick. After the bikevent warms up and you Crack the throttle the idle with start surging (climbing and lowering) but if I turn the idle screw down just a take it doesn't really want to idle. With my experience racing Jr dragster I want to say it's lean on the idle circuit? Or is it different with these 2 strokes. Also once you hit full throttle before it hits it's highest Rev it bogs. Is this a lean issue or you do you think it could possibly be my half a$$ fix to the magneto to get through bike running.
