It is also within the realm of possibilities that you could
replace the regulator with a much more elaborate DC to DC converter type.
This could "buck convert" the high voltage (at high RPM) to low voltage
with greater amperage.

Bill, I am interested in this possibility. I'm a mechanical engineeer, I know enough about solid state electrical circuits to get into trouble. Are the parts for this circuitry available reasonably? Are they dead bang reliable?  Both items are vital if several of us start using them. Also while we shunted into talking about the Harley alternator in the thread, I believe the racemate alternator is designed to a higher rpm use. IE doesn't produce full voltage and amprage until higher RPM normally.
