Are you talking about the Compufire stator/rotor/regulator from Amazon that I gave you a link for? Otherwise don't you have a Harley dealership over there? That's where I started my quest, knowing that I was gonna be paying far more money than I would by getting aftermarket parts on-line, but I wanted to actually hold and measure parts before putting money down, which was a good idea, because there are a few different models and sizes, so I examined them as best as I could, but they were a little hesitant about me opening sealed boxes to make my choice. But I was up front with them about what I was doing and why I didn't have actual part numbers to know what I needed. They had no problem with the aircraft application idea, but I'm pretty sure they thought I was a little crazy, but my $400 was still all they really cared about.

Hi Neil;

   I can't confirm for certain but yes, 2.77" sounds about right.

  After the flywheel and damper drive modifications to increase clearance, I still only had 1.43" to squeeze it in there, so that is why I also shaved a little off of both sides of the rotor cup and also machined a shallow depression into the backside of the psru backplate to allow mounting the stator close to the plate and still have clearance for the windings.

This link will show a pic of where I measured the 1.43"

  At a little over 1.5" before any modifications to increase that room, then you are much better off than I was when i began. 

   When I decided to try it, I really had no more than the desire & determination to experiment and a "Hairy chested hero" idea that I set down $400 at the local Harley shop as a bet that I could make this work, knowing also that I was modifying an expensive PSRU, that is no longer available for purchase. That gamble paid off for me and I proved that it can be done.

  So I would say that you gotta ask yourself whether this is something that you really want in your own installation and if yes then put that money down on a single rotor/stator and go to work to see if you can make it work for yourself on your own design.

  Then if you are as happy with it as I am with mine, you can figure out at what cost you can offer it as an option.

  If I were in your shoes I don't think that I would go to the trouble if your only motivation is to provide it as an option for others. But if like I said, you want this for yourself as well, then go for it and if successful and affordable, then others can have the option of one as well.

Todd,

                   From what I can gather  the ID of the stator is 2.77
inches.  Does that sound correct?    To land a unit from the US or buy
in OZ , the cost is  Pushing $375 AUD or $285 USD.  I have a little over
1.5 inches to mount in between the drive and the plate. Do you remember
what space you had?  Thanks,  Neil.
