Interesting :¬) I guess the other things to consider are the pressure in the pipe, the speed of the gasses and the length before it hits a point where the pressure can drop. In the article they talk about megaphones allowing a 42inch pipe even though the racing rules said it had to reach to the rear...

Yep, and added to that is the back-pressure caused by the length of the exhaust being important in keeping the correct flow of the gas through the head so a too free flowing exhaust can just lead to more mixture disappearing.

Good effort!

A good friend of mine is riding his BSA WM20 down to Monte Cassino. He's nearly there but the ignition & electrics are failing rapidly. If anyone in the area can assist he'd be very grateful.

Seems like a good idea to be able to access the chain & engine sprocket without disturbing the clutch etc
