Compu-Fire Vs. BDM Charging (Same?)

I, some day will be rewiring my bike, and had originally planned on removing ALL, and I mean ALL, BDM electrical items. Not including the lights and speedo.

Is the BDM 40 amp 3 phase charging system made by Compu-Fire or is theirs a much better unit and not related?

Here is the one I was looking at:


55560 1981-1999 EVO Big Twin includes vented rotor (aftermarket engine, closed primary systems)

The Compu-Fire 40 AMP 3 Phase charging systems

Provide 25 AMPS at idle and 40 AMPS continuously above 2800 RPM. The unique narrow rotor and stator combination fits Softail/Dyna primary cases and the voltage regulator bolts on without any frame modifications. The precision balanced vented rotor keeps the stator cooler in closed primary systems to maintain maximum output under all high current draw conditions. The large flanged seal spacer provides maximum support for the rotor and the voltage regulator output is calibrated to 14.25 volts from idle on up.

Jake,
I am with you brother on this one....
I do not know the answer here on the charging system but I will be doing a make over this winter too. I am speaking to someone on Thursday about options as well.

I can't answer your question either Jake but I put a compufire VR on my bike a few months ago - I got the one rated at 32 amps but can handle a lot more - not had any problems with it all. It has a separate wire for grounding which I guess is better than the BDM VR's which don't.

From what I can tell the compufire system is as good as it gets.

So it would probably be a no brainer that if one was removing all BDM electronics, they would also replace the VR and Stator as well and not leave it in there???
