Electrical help. Want to convert old bike to newer style voltage reg

I have a 1971 sl 350. I want to convert the older reg/rect to a newer style. I have talked to baja designs and they could not give me an answer. They have a guy but he is out of town so I will have to wait to hear back from him.

Knowing that I will forget to call them next week I thought I would ask here.
I was thinking that an alternator is an alternator is an alternator. That any 3 wire reg/rectifier should work provided it is rated for the stator.

Can anyone help me out?

Thanks

-John

The first thing to determine is if the alternator is single phase (two wire)or three phase(three wires), lots of old bikes were single phase but I don't know if yours is. FWIW these people make economical rectifier/regulators for British bikes, one might work for your Honda if the specs are similar

many newer 3 wire bikes do well with honda mofset type regs. like aprilia and ktm.

I've gotten the regulator/rectifier combo from ricks motorsport electrics. You remove the old reg/rec hook this up to the two or three yellow wires coming off the stator and plug the other two wires to the positive and negative of your battery. So it goes from the stator to the new unit to the battery bypassing all the old wiring. I thought it was pretty trick. This was for a 360 but not a lot of difference, pretty sure all the stuff is the same.
