This is actually the first time I've ever had anything to do with Harley's. Never was interested and figured pigs would fly before I was. If this works then a part of a hog will fly.
I'll keep it in mind when I start to shop for a reg.

Todd,
For some reason I have had bad luck with Harley regulators and have had better luck with Custom Chrome regulators - just a comment to consider.

Hi Ernest, Kelly and others;
I promised myself I wasn't going to do any experimenting this time around, but here I go again.....
Today I went down to the local Harley shop and lost $381cad. And I just have the rotor and stator to show for it. I still need to buy the regulator, but I figure I shouldn't throw that money away until I can definitively make this work. Kelly, you probably did the right thing by ordering from Compu-Fire, but there is something to be said for holding the parts in your hand and fitting & measuring it first. The store owner is also a pilot and was quite helpful when I told him what it was for. These are genuine Harley parts, so surely I paid for that privilege as well.
Stator 32amp #29970-88DHD
Rotor #29957-81BHD
Unfortunately, while I think I can make this work, it ain't gonna be easy. It's going to require a few mods to the RD-1 mounting plate and to the flex plate dampener. The rotor will also require some alterations. This rotor is 1.52" thick and the space currently available between the dampener and the mount plate is 1 3/16". And the edge of the rotor also lines up with the ring of bolt heads holding the RD-1 together. To accommodate this I plan to countersink these bolt heads so they are flush with the mount plate. There also needs to be a path for the stator wire to pass under the edge of the rotor. I plan to machine a slot 3/16" deep x 1/4" wide x 1.5" long into the backside of the mount plate. There will have to be several mount bolts to fasten the stator in place which will pass through the mount plate into the oil filled internals of the RD-1. I plan to drill these holes and then machine an o-ring groove under the bolt heads. I believe these will be located in an area where they will not interfere with the sun gear so they will not need to be countersunk. That should be all that's required of the mount plate, but that still only leaves 1 3/16" to fit in a 1.52" thick rotor.
The rotor will require the splined center to be enlarged to fit over the dampener. I'll have this done on a lathe and while it's on there, I'll have a little taken off both the face and the back edge. I'll gain very little here, but I'll also ensure that they are true.
Now the dampener is where I think I can make the required gains. The steel center hub is riveted to the front side of the aluminium dampener plate. I think I can relocate this hub to the back side of the dampener plate. This should give me an extra 3/8" to work with. The backside of the center hub on this dampener plate will likely have to have 1/8" taken off the center to allow for the flywheel nut, but there is lots of material here. This part is a little hard to describe so I'll take pics as I go. And surely there'll be something I'm overlooking. But I'm betting $381 that I can do it.
This will require the services of a machinist and as luck would have it, the latest guy I signed onto play on my hockey team happens to be a machinist out at the mill I work at. So I'll get him working on some of this next week.

Ernest and Todd,
Ernest what is output amps of the system that you bought ??.............I just sprung for the
"Compu-Fire" 40 amp system................Link attached...............Sure hope it works as it is
fairly pricey................I have plenty of room for it since I am using a auto trans bell housing
between engine and RD1C redrive.............
