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!

I suspect you will still have problems with the battery losing charge while you are riding. I was getting about the same numbers with a new battery and rectifier and on a long ride the battery would get low enough it would not restart the bike. I pulled the stator out and found it had burned coil. I sent mine off and had it rebuilt for a cost of $250.

I thought that was low. The service manual spec is
Regulated voltage: 14.0 – 15.5 V at 5 000 r/min

I have a good friend who rebuilds starters and alternators. Maybe he can take a look at my stator.
