What I have never heard it explanation, however speculative, of why these belts seem to be fine when these engines are used in a motorcycle frame, yet they seem to have a very short life when used in the Morgan. You would think with the engine sitting up front and that time in case exposed to the wind that if anything it would be running cooler than it would be sitting out the side of an air cooled motorcycle. I don't know if any of the armchair Engineers here on the board have an idea about the actual cause of these failures.
