Memory whiplash.... Working at an HD/Kawasaki shop in the early 80's and a guy brought in his Z-bike for a slipping clutch. Turned out his clutch was fine, but he never lubed or adjusted his chain, and he'd worn the rear sprocket teeth to nothing and they pretty much had laid down towards flat. Whenever he got on it, there wasn't enough chain/sprocket engagement, so the chain would freewheel and rattle over the rear sprocket.
