So today, I was helping my Dad tear down his rear-end to check his splines. All good. This got me thinking, what if the rear tire fit on my 750? I think the final drive would mount right on and it would also replace brake drum with a disc brake. Only thing I am uncertain about is the width of the 750's swing arm versus the 1500's. Anyone here attempted this conversion? I think it would really update the rear end by having a disc brake versus the current drum.
