Wondered if anyone knows or has a alpha 41(micron) exhaust for a 750 f1? Not sure of people views on the alpha 41 or even if you remember them ? They were very short and stubby only just exited from under the engine. I had a Saturday job there in the early 80’s and would love to get hold of one for my f1. I spent a lot of hours fitting baffles and putting them in boxes. At that time it was only the 2 stroke pipes that were known as micron. Sorry getting a bit boring now 😴
