Hey guys I have a 02 rc51. Im having intermittent charging problems. It charges fine sometimes. Then it will stop charging sometimes if I hit a bump etc. ive checked all wiring and have found no shorts etc. my question is I am thinking about buying a stator. From what I read about it usually a stator is either good or bad. will a bad stator charge only part of the time? If goingbad? Also what else is needed for stator change? thanks!
