Re: So Close
Many times, the killswitch will be mounted on a painted handlebar and the engine won't turn off. Move the switch temporarily to bare metal and see if it works. If it works, then scrape the paint off under where the switch needs to be, then bolt it down. If that doesn't work, scrape the insulation off any part of the wire, touch it to ground with engine running. If engine dies, replace switch. If engine does NOT die, trace it back to the coil and repair connection.
You can also run the killswitch wire to the sparkplug wire to get it to die.
Safest way to mount the tensioner is to have someone weld a simple bracket to the frame. Then add a bolt and skateboard wheel as a tensioner.
