If you have a copy of Dave Richardson's Guzziology, you may want to search there for a possible resolution to your V7 Sport's starting problem. Section 17-20 in Version 8.0 of Guzziology has a section titled "Back-up start switch for loop frames, V7Sport, 750 S and 850-T models". As an aside, a similar starting problem on my 2006 Norge was resolved when I installed an additional relay and re-routed wires (can't remember how its been so long ago) between the ignition switch, the battery, a ground, the solenoid, the starter and the connectors on the original relay. Apparently, Norge starting problems were common and some Texas firm developed a solution. I bought the kit, installed it (came with wires, connectors, a relay, instructions) and never looked back.
