I thought you meant backfiring too, ie: rev, then hit the kill switch.

What you mean is hit the kill switch, then watch and laugh as the rider fiddles with ignition, clutch, side stand and neutral, trying to figure out why the bike won't start.

Won't work for me, I flick off my kill switch every time I stop the bike, so I'm used to turning it on every time.

Sitting next to somebody at traffic lights, then hitting their kill switch just as the light turns green, and riding away, is much more fun anyway!
