    Bare minimum wiring needed to run...

    Hey guys i have a gs550 motor from a 1980s bike installed on my 1968 triumph frame. Im trying to wire it up now to start and im wondering if someone could tell me the bare minimum wires i need to get it to run with a
    Kick start. Thanks gents.

    The 1980's era 550's all have electric start. Those bikes also have electronic ignition. As long as you are powering the spark the bike should run. Of course, most people would prefer a charging system too, and that electric starter too since bump starting is tiring. A 1977 - 1979 550 has points and kick start. You could get away with less wiring on those bikes.

          You simply need to power the coils/points and the bike will run. A few more thing to consider are an ignition switch, head lamp, charging system, and turn signals.

            Okay so now I realized the motor I bought had the DynaS ignition I vaguely remembering the guy telling me that when I bought it aswell. So I have the ignition all wired up now as per the DynaS instructions... I have the ignition wired up aswell as pulled my switched 12v from the switch on the drivers side handle. Im assuming I need a battery to start the motor aswell seeing as though the engine needs +12 for the coils to fire??

              Just a chance, but…

              Did I hear that Brit bikes are wired with POSITIVE as ground?
              Hope you check that before you go live.
