on a newer bike there is a plug that only has the 2 wires that go to the start run portion of the switch. Not sure which ones it is on the older bikes. you can simply trace the off wire that grounds the ignition and clip the other 2 wires. This will make the bike start no matter which posistion the switch is in, either start or run. The bike will still die when switched to off. This disables the retard function of the ignition givving a few more revs up top. slightly noticable on the top end.
