Simple ON-OFF Switch Won't Cut It
Millhouse, one concept I'm trying to convey; the simple on-off ignition switch you suggest won't cut it, as the KLR600's ignition is configured from the factory. A single-pole, single-throw ON-OFF switch won't kill the engine, because the exciter coils are permanently connected to the CDI.
A simple ON-OFF switch connecting WHITE to BROWN will turn your lights on and off, permit operation of all other 12 VDC stuff like your horn and turn signals, your tachometer, but . . . won't have any effect on your IGNITION circuit.
Thus, you have, "The KLR Engine That Will Not Die," unless you ground the exciter coils, as the existing as-built switch logic does.
Can you work around it, "cheat" the system? Yes, of course, but you will then have no positive kill mechanism, a feature some think desirably contributing to safety.
Your bike, but I wouldn't mess with the ignition switch/kill switch logic lightly, myself; YMMV!
