I'm much more mechanically inclined than electrical so I tend to follow others advice when wires are involved. On my 73 Norton Commando with zenner diodes and stuff the easy low charge voltage fix is the shindengen sh775 rr. It takes the 2 or 3 wires from the generator and connects + and - to the battery. They originally came on Polaris 4 wheelers and gained popularity with the old school 4 stroke crowd. Nowdays I see on forum's for modern bikes with stressed charging systems they use the sh775 or the next version up. Why am I not hearing about these on old 2 strokes like RD's?
Thanks for any feedback and Merry Christmas!

well, rds use an excited alternator, and only had a 4.5 ah battery, there isnt much draw. triples and others can use permanent magnet rotors, so any typical 2 wire reg/rectifier will usually work.
most vintage 2 strokes arent stressing the charging system, and they also run at typically higher rpms, so charging isnt really much of an issue. most of the aftermarket rd reg/rectifiers are derivatives of SOHC CB750 aftermarket designs.
excited alternator, thanks Mark, I'll do some reading. Now i can concentrate on grafting a full new HPI or other ignition charging system to my oddball stinger and bridgestone
