VN750 R/R replacement specifics

Can anyone tell me if the R/Rs are model/year specific? If I need one for my '93 750 can I use one from a '92 or '94?

Well Johnny A, I would have agreed with Jace before I checked out his link to Kawasaki Regulators. I have been under the impression that the r/r on the vn750 has a 6 pin electrical connector on a wire pigtail, and interchangable between all model years. This link shows 3 different r/r models, two with no pigtail (including your `93 model), just a direct 6 pin plug on the r/r body. The third has a 4 pin pigtail and 2 separate, individual wires to plug in. They are specified for different years, and two have a different spacing for mounting holes, while third does not specify at all.

Check out Electrosport`s Model ESR 260.

It is $20 more, but has the pigtail mounted 6 pin connector, and is specified to fit all vn700/750 models from 1985 to 2006. If you are going to do a r/r relocation to the frame by the left foot peg for better cooling, when you replace it, you may need the little bit extra wiring included in the pigtail. The reg/rect in jace`s link may be just as reliable, when installed, as Electrosports is. So take a look at yours to see if it has a pigtail connector, and decide which one you want or need.

The part number for '92 and '93 is the same: 21066-1055. The part number for '94 is 21066-1089. My guess is that that electrically all year models are the same and the differences are mechanical.

Here's one that LAnce328 found on EBAY for me.

As close to the original as I have found and made in Japan. Installed (relocated) this weekend. Seems to be excellent quality. I guess time will tell. I have an '89 but believe yours should be similar. Think they changed in '94. Good luck wih the changeout. Piece of cake, really.
