I picked up a kx 125 motor from some nieghborhood kids awhile back, with the intentions of making a sweet ass go cart. The motor is supposed to have a new crank in it as well as a new topend. The piston is new, but I have no confirmation on the crank. It had spark when they tore it apart to rebuild it, then when they got it all back together, it no longer has spark. Its all there minus the flywheel cover and a few bolts here and there. I honestly don't know whats wrong with it, I haven't messed with it at all. I have the pipe and radiator to go with it. I'll trade for parts, nothing in particular however I do not need a bunch of stock stuff, unless its really nice.
