Or...I don't know why you couldn't remove the tour pak and drill holes in the tubular frame mount that are one inch (or seven eights) further back from the stock position. I suppose there might be some concern about structural integrity, but I can't imagine it would make that much difference.
Also, I don't know exactly how big you are, but I think if you're big enough, Richard Simmons will come to your house and help you lose weight
