Haha, well it's my friend's bike, but I was the lead on building it, so I can certainly take the blame. I'll give that a look when I see him to help him with it.I am taking a belated stab in the dark here. The guy ran the display wire between the motor and the BB shell and up the underside of the down tube. That is my prediction. The motor mount is shifting ever so slightly under load, pinching the throttle wires. Remember in sex education class when the guy asks a question about his 'friend's' problem?
