They've been used to produce the electrical power in every power-sport toy that I've ever had, from outboards to snowmobiles. Unfortunately the ones I could easily examine all were too small of a diameter and Ernest had already determined that the Harley unit was likely big enough in diameter. But considering the cost and ease of availability in Oz, I think I would take a close look at outboards and see if any of them could work. Next I would look at Japanese made ATV's. I know it's a lot of extra research, but it may yield a better solution.

=C2=A0 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"

=C2=A0 So I would say that you gotta ask yourself whether this i= s 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.
=C2=A0 Then if you are as happy with it as I am with mine, you c= an figure out at what cost you can offer it as an option.
=C2=A0 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.
