      <div>  After the flywheel and damper drive modifications to

      <div>  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. </div>
      <div>   When I decided to try it, I really had no more than the
        desire &amp; determination to experiment and a "Hairy chested
        hero" idea that I set down $400 at the local Harley shop as a

        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.</div>
      <div>  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.</div>
      <div>  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.</div>
      <div>  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.</div>
