I got to thinking, (Always a bad idea for me)! It can be done! Only way ive found is to mount to rear rack! there is real;ly not much to get in the way, but you will have to strengthen the rack considerably and the mount a piece of thick steel with the correct mounting holes. You would also have to weld the sprocket up to the centrifugal clutch, CuZ I dont believe they make a stock clutch with that size teeth!
