My favourite Killswitch occasion was when, at the end of a trackday, a bloke was bumping the nuts off his old CBR for about 10 minutes around the paddock, I was packing stuff away but others were helping so I just continued to load my bike for the ride home.. It wasn't even firing and my first though was Killswitch but a good number of riders had been over to help so I just assumed at least one of them would have checked.. After I'd finished packing I mucked in to help push, but thought I'd have a sneaky check of the switch myself as now I was about to throw my own sweat at this, yep, it was off.. I flicked it on and thumbed the starter, fired up.. The bloke was so embarrassed he just rode off leaving the rest of us laughing.. 10 minutes he'd been pushing that around, still makes me giggle now.
