Hi Ernest;
    You were working on installing an H-D generator between your engine & redrive, which I have a great interest in. Last post I find about it was last August in which you were promising pics soon. Did you ever get this done?
    Also from your info there was a link to CompuFire, where it looks like the best option was this one;
- *55540* 32 AMP EVO Style (Narrow Stator/Rotor) Aftermarket Engines $250
but your last post on the subject says;
- BTW, I have the Harley Davidson generator now. 38 Amps. $288.17. 9lbs.
So did you buy this one direct from H-D? What are its dimensions? Part #?

I'm currently in a position where it's the ideal time to do these sorts of things, so I'd like to take a real close look at it now and try to make it happen.

The stator is held off of the back of the PSRU with 3/16" coupling nuts.  One is shifted to the side, so the installation is in effect keyed to only fit one way.

I don't like the stand-off.  I tried to fabricate it from .065 4130.  It isn't even close to being centered.  I am working on setting up an aluminum casting rig.  I'll cast, and then machine a mount so that it is guaranteed centered and mounted solid.  The rotor mount is bolted to the flywheel along with the standoff plate that holds the clutch plate that provides the connection between the e-shaft and PSRU input shaft.  The rotor has two sheer screws to hold it in place.  The replacement mount will come up the rotor's sides to further lock it in place.

All I gotta do now is get 'er done.
