About a month ago my bike refused to start on my way back from Bear Mtn. in New York. My buddy and I were able to push start it. It ran for about 10 miles then the FI light started flashing then when it went solid the bike stopped running. We push started it again and it ran for another 10 miles and the same thing with the FI light and again it died. My friend had to ride home and we ended up putting it in the back of his pick-up truck. My battery at that point was a 6 year old Parts Unlimited YTZ-12bs. I purchased a new Yuasa YTZ-12s and installed it. Starting voltage was 12.7 volts, dropped to 12.3 when I started the bike (It's supposed to go up to around 13.5 to 14.0 right??). I did the diagnostic test for the stator and it was up to spec. I borrowed a friend's rectifier (which works perfectly in his RC51 - he gets 14.4 volts with his bike started) and we swap and it's the same result on my RC.. 12.2 volts! So if my battery is new, the stator is up to spec (.3 ohm resistance at all 3 leads), and the rectifier is mechanically sound how come my battery is not charging?? Please guys, I need your help. I am a novice at using a voltmeter but I have the owner's manual which helps a lot. Help!! Mike
