OK, I re-jetted till I was blue in the face, decarbonized the exhaust and exhaust port, checked the reeds, used 5 different plugs, cleaned the carb several times, clewaned the air filter, changed the spark plug cap, checked resistance on all the electrics, per the manual, and I´m still at square one. It still sputters at full throttle. The only thing I didn´t check was the stator, which is behind the flywheel. I don´t have the tool to remove the flywheel, thats the only reason. I did notice some weird coloration on the stator, like it was water damaged or something. The guy I bought the bike from let it sit in the weather.. Please Help!
