I went for a ride a few weeks ago and my phone went flying off my handlebars at 36mph, only to be run over by 2 escalades. I was really happy, about to push 37, then really sad.
Surprisingly, it still works and is now the dedicated speedo for the bike, with a tether for backup.
Last night, I got to cut and strip a spark plug wire with my teeth on the side of the road. My cdi slipped down, and damaged the wire where it would not screw back on.
