I bought a ´77 400 about mid-summer for my Wife, but as she couldn´t reach the ground, I have been riding it. I would like to trike it for her if I can find a chain drive differential reasonable. That way it could remain a vintage bike but she could ride it. I also want an electric starter for it so she doesn´t have to bust her shin to get it going. If any of you have info for me about parts to be had, please e-mail me. Thanks, & howdy! Mark, the gingerbreadman
