Always something. Tried to take it over to a friends and only made it 2 miles before the engine died with a dead battery. Seems the voltage regulator was also kaput. Got a replacement which arrived NIB and 2 days earlier than predicted, put it in and the problems seemed to go away. NOTE: The VR has to dump about 6 Amps of current when the battery is fully charged and gets too hot to touch very quickly. Probably gets too hot to work shortly after. The original mount was a bracket on the rear of the engine case, right next to the exhaust collector can. Good thinking.
I built a new bracket with a big finned heat sink and mounted it on the opposite side from the exhaust system. This seems to be working. the regulator is running much cooler and the engine seems to like having a full shot of power to the ignition.

Rear view. Big fins. Lots of air.
Need to put 5 miles on it around the 'hood to prove it is now ready for prime time. The neighbors will be somewhat annoyed, but tough.
