I have a 75' XS 650 Bobber. Currently the bike is running a 12V-3Ah battery (kick-start only), but I'm getting sick and tired of kicking at least 20 times before the bike starts so I want to hook up a 12V-14Ah battery to the system. Can I just connect a wire from the starter and another wire from the + side of the battery to a push button? Shouldn't be any more difficult then that? How thick should the wires be?
