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

 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.

        You need not get too concerned about the RPM. Only the magnets spin.
