Here is something that has never happened to me i went to get gas yesterday tried to get the gas cap off and no luck it just spun wouldn't tighten or loosen. Got it back to the garage and had to use a screwdriver to break it seems after i got the chrome cover off that the screw inside had come loose, something i had never thought about checking before, Drove to JP cycles today picked up a new paint protector and flush mount Gas cap all is good
