Group,

          &nb= sp;           Have done s= ome investigation into mounting another generator on the cushion drive and I think it is possible if I use the Racemate rather than the harley.  Cost appears to be similar but the dimensions of the Racement seem more adaptable.  I will have to alter th= e cushion drive to fit, but that is simply an annoyance at this stage.  Guessing the cost involved it looks like $350 for the generator and regulator, plus possibly an additional $200 for machining making an additional $550 USD for the generator.

IS this cost effective??  You only can answer this for me.=   The generator puts out 35 amps.

What say you all?

Regards.  Neil
