So last nith was a bit on the chilly side when I fired the bike up to head home. About 60 degrees out. Bike started fine. Let it run for about 5 mins before I headed out. About 2 blocks away I stalled it at a stop sign. Was riding 2 up and just not enough throttle I'm guessing. No big deal. I put it in N and hit the starter............buzzz. No juice. Would turn over once and buzz, lights dimmed. Dead battery. WTF. So got my woman to push and popped the clutch and it fired up. Kept the RPM's at around 2000 and the headlight was nice and bright. Everything seemed fine. Rode it the 20 miles home no issues. Turned it off when I got home and then started it right back up. Shut it off. Went out this morning, fired right up. Shut it off. Took the seat off and put a meter on the battery. Started right up. Was only 12vdc at 1k rpm. @ 3k rpm it was charging 13vdc. Seems pretty normal. No drain on the battery when the bike is off. What the hell?
