There is this movie that has a gas station and a sort of like an homemade bike, and the long hair fellow (main character) he stops at the gas station, but before he could get down his bike just fell in pieces like the exhausts, seats and everything...

Then there is another scene when he stops at the gas station there was a leak in one of the gas tanks, and he took out his chewing gum and stops the leak. Most of the scene his bike keeps falling apart.
