I would think a switch might be a smart move. If only for the fuel injection. When I lived on the Big Island, the fuel quality was poor and it ate carburetor parts. Not an issue with FI. With a hack I bet you could find a car tire for the rear. Save up and install a leading link front end. I once dreamed of a hack set up such that you could roll up with a special wheel chair, lock it in and it becomes the sidecar wheel. Like a transformer.
