It's a SDG pitbike with the Lifan 125cc motor. I replaced the factory stator setup with an inner rotor kit because the chain took out the old one.... I installed the new inner rotor kit, cdi, and wired it all up and no spark! The new motor has only around 4 hrs on it now and its getting fuel, just no spark. I've yet to check the air gap on the stator and flywheel, but it's not far off. I've got everything wired correctly though. Does anyone know of any other things i could check? What about checking voltage and all from the stator? What should it be? Any help would be greatly appreciated!
