Regulator/Rectifier

The regulator/rectifier on the VFR is a common point of failure. Usually, by 20k miles, it will have given out.

Honda

Honda has replaced the old regulator/rectifier with a redesigned model which has more substantial cooling fins.

OEM

The stock unit appears to be made by Shindengen. Their generic regulator rectifier can be purchased at their online store.

According to this post, the 1990-1997 VFR-750 originally used the SH612-12, which was superseded by the improved SH638-12. Neither of these part numbers are listed on the Shindengen website.

GSXR

GSXR regulator/rectifiers can be adapted. They appear to be much more substantial than the VFR units. They seem to all use pigtails, which makes it easier to adapt for use with a VFR.

This post describes how to wire a "five-wire" GSXR regulator/rectifier to a Honda Superhawk:

The three yellow honda wires go to the the three gsxr black wires. It doesn't matter which goes to which just that the three yellows go to the three black. The honda red wire goes to the gsxr black with red stripe wire and the honda green wire goes to the gsxr black with white stripe wire.

This post also discusses a 5-wire GSXR unit.

3 black gixxer to 3 yellow honda
black/white gixxer to green honda
black/red gixxer to red honda

R1 or YZF

R1 regulators appear to have massive cooling fins. However, they use a plug mounted directly to the body of the regulator, much like the standard Honda unit, which may make it more difficult to adapt for use on a VFR.

A page on using R1 regulators on VFRs.

This post explains the single-connector R1 pinout:

The Yamaha's male spades are arranged like this:
- - -
 - -
The three spades at the top are the 3 phases of AC power coming from the stator (the yellow wires). They're interchangable. The bottom two are the (+) and ground. I can look at my VFR tonight and tell you which is which.

A follow-up says that the ground is on the 'left' in the above pinout.

Connector and Wiring Harness

If the regulator/rectifier goes bad, the wiring harness connector may overheat and melt or burn. This page provides details on the Honda kit (p/n 32110-MWO-305) to repair the wiring harness.

Relocation

This person relocated their regulator/rectifier to a spot at the front of the bike.

Resources

92,836 miles on a VFR750, though it's an older-gen VFR.
