I never use the kill switch. The reason is, most of the time when I turn the engine off, it's to park the bike outside and I have to lock the forks by turning the ignition switch anyway. Plus, I hate to start the bike in gear with the clutch pulled. Not good for the starter and the battery. That is, if I remember that I used the kill switch and that I'm in gear. Hate this stuff.
Ignition in "lock" and in neutral is the way I park, unless the parking space isn't flat.
