Stove Pipe?
I removed the knob key once in the beginning to prove I could do it and to test the other keys in the ignition, otherwise it remained in the ignition where it belongs.
I use the spare keys to work all the other locks period and probably will make the "knob" type spares from Radio Shack for the bags eventually. Why risk bending the stove key??
I locked the steering once, again to prove it could be done. No one has messed with my bike (so far) but then again it's never been far from my sight when parked or at least not for long. I work at an Army Reserve Center so the risk of that has been low.
Kipass ROCKS!
