    LSR rules require a tether. I can’t find a Normally Closed switch on speedy delivery, and the one I have is Normally Open. Not sure what on the CDi I could short to ground, so I’m considering just wiring it into the kickstand wiring- looks like that switch closes when the stands down.
    Anyone run a switch like this, or have a better suggestion of something that will kill the bike if I run it to ground without burning the bike down?

    I wired everything thru a relay, & fed the power to that via a tether, cut the power to the relay, everything dies.

    So I validated- an NC switch would do it. This NO switch operates the opposite of the kickstand- kickstand up the switch has continuity, key in the kill does not.
    Guess I better find a speedy delivery NC switch.

    I use a 30A fuse holder (& Fuse) wired into the earth circuit. Drill a hole through the 30A fuse and connect a tether to it. Works well enough for it to pass scrutineering.

    you sir, are a genius- simple, cheap, normally closed, low friction.
