A buddy put new bars on his 2012 RKC last year. He just put a different sent on today and noticed that his front brake line had the coating melted off in a few spots where there were zip strips or bends. The heat came from inside the line out. Is it possible that on his last bar change he pinched a wire and the brake line from the handlebar caliper was acting as a ground? Is there a ground or strap that connects the bars to the frame somehow? Could he have forgot to reconnect this ground strap?
