funny story with hte kill switch, i bough tone, and was going to install it at the track, we had a full race trailer and set up, and i was 60 miles into the trip up when i realized i had forgotten it, so i went up anyway and hoped somone up there would have one i could use. well we took a small threaded eylet, heated ip up red hit with a torch, and pressed it into the bottom of the on/off switch and held it while it cooled, hooked up a lanyard to it, and there you have it, pull on it, and the switch flips up, and off the bike goes
