don't know if i can help, but i have a 80 custom with starting trouble. when it will crank it cranks right up. now is your bike not starting or not cranking? mine will not crank, push the button and nothing. i know that it is electrical and will start tracing the wiring and components to find. if yours will not start make sure the choke is working as is it should. these old bikes have a hard time starting without the choke when they are cold. do you have a manuel. if not get one. from re-reading your post it might sound like we have similiar problems. possibles: bad wire, bad starter relay, bad clutch switch, bad nuetral switch, bad connection. when i figure out my trouble i will post. you could try jumping across the relay and see if it will start, but don't buy a bunch of highdollor starter without bench testing it and maybe checking brushes, bushings yourself. you may have fixed yours already, i just noticed the date on your post. anyway happy riding.
