I know they were used in supermono, does the motor differ in tune between the Aprilia/BMW/husaberg it's used in?

Obvs better to keep it 2-stroke, just throwing some right hand sprocket options out there
mostly the head, the aprilia has 5 valves
no extra power though
I dont think they even make 50bhp
and you would need to fabricate somewhere to hold the engine oil
