You shouldn't have the exhaust port at the rear of an air-cooled engine...
Sorry, Serow, I must contradict you.
Eyewitness news: Ducatis have the rear cylinder with the exhaust port looking back ever since they came out with the belt-driven OHC Desmos.

As if THAT weren't enough, Borile, a "quasi-Buell" Italian equivalent, uses a custom made 450cc single originating from the rear cylinder only of the 900cc twin.

Rather, the guys is using the wrong kind of air filter; looks nice and shiny, but actually pushes air away from the intake...
