Bill and Bill,
I spoke to a Motorcycle Electrics technician yesterday, said he had 
used Harley (Accell) alternators on various racing applications that 
rev up to 8-9000 rpm with no problems. He recommended the use of the 45 
amp regulator on the 25 amp alternator as it was more robust and better 
design. I did not mention 'buck converter' as that term is new to me.  
He also said that it was only the balanced magnet annulus that spins 
and had no history of mechanical failure.
Thanks for your input here, WD, I too, know just enough to be 
dangerous!  FWIW, Dave McC
