Well, we got the bike 100 miles home. It took one breakdown(about 40-45 minutes after leaving) and sitting under a thruway bridge before help arrived with jumper cables. Two charges later(the second we did as a precautionary jump at a rest area), the bike is safely in the garage.

The battery has been sitting on a trickle charger since I got it home again.

Once again scouring the manuals and internet for charging system defects/troubleshooting/known problems, I have decided that my alternator rotor is bad - the resistance between slip rings was less than 1 Ohm, consistently.

After looking around for a suitable replacement or solution, I've found this: http://www.ebay.com/itm/Honda-cb650-cb750-cb900-cb1000-rotor-rebuild-service-/180896474621?pt=Motorcycles_Parts_Accessories&hash=item2a1e4525fd#ht_1871wt_1156

I'd like to give it a try. (Thoughts?)

HOWEVER, when I went to remove the rotor, I absolutely have tried everything in my garage to get that darn bolt off, and I simply can't. I've tried hammering, wrenching, air impact wrenching, manual impact wrenching(old school with a hammer), PB Blaster. I've shifted to fifth gear and braked, and the clutch just slips(another problem?).

So I'm giving up for now and hopefully riding the darn thing to a professional mechanic tomorrow.
