Actually i was interested in the same thing. see the Old bikes eat up RR's (regulator rectifier's) alot...I think its horrible alternator designs... but here's why they blow out...when you rev up the engine..the engine puts out 280+volts into the voltage regulator and some rectifiers can't handle that voltage for a long period of time..they heat up...and if even one diode on the rectifier blows out you'll be stuck with a half wave and little or no charge capability at normal driving range. hence the RR is gone...I restore old bikes too. buying the Bridge rectifiers for high current is fairly easy you can by both 1 phase and 3 phase bridge rectifiers. they have to be put on a heat-sink. The next thing would be a linear voltage regulator...for more current you can Google "high current linear voltage regulator" and it should show you how to Parallel them quite efficiently but that does not help with the input voltage. see it can vary from 14-280 plus volts and that pretty much makes allot of linear voltage regulator's useless. what i don't know is the constant sustained current usage of a motorcycle's electrical system. Then you have the current usage when it is rev'd up, which is a guarantee. so basically i need help here just like you do. I need a linear voltage regulator...(i can have two+ in parallel with load balancing Resistor's and caps.) WITH a low drop out, High input voltage up to 400v and a stable out put voltage of 13 to 14 volts...this means it has to be something like a LM7813 linear voltage regulator but the capability of handling such high input voltage and current and out put at least twice the minimum sustained load current from the bike's electrical system.
I hope you understood all that. If you remember how to make a good one then email me the info too. at email@example.com. I really wanna make one too.

Dick smith has very low cost kits. If you can't get to them then try jaycar. You csn search their site for what u need.
