My battery wasn't charging, and I suspected either the rectifier or the stator. Decided to replace the rectifier first since it was less expensive. Removed 4 pieces of Tupperware (thanks, LeDude for the videos). Installed the new rectifier. My battery voltage with the bike off is 12.4 volts. With the bike idling, I'm at 13.5 volts. At 4000 RPM, I'm at 13.87 volts. So I guess I'm OK. Wish I was at 14+ volts, but it's good enough now. Hope I don't have to,replace the stator any time soon. $500+! Yikes!
