350cc 25 to 35 hp to 750cc 50 to 65 hp Honda and Kawasaki motorcycle engines 4 cylinder over head cam smooth running, light weight and cheap. All we need is some one good with a CAD/Cam software to design a new crank case with a built in chain gear reduction connected to a prop shaft and oil sump with pump. I have been looking for a good 4 stroke light weight and not cost more than the airframe. and a 4cyl 4 stroke would be a smooth engine. look at the old 1920 and 1930 plane engines 4 cyl 4 stroke. Or remake Azania engine Anzani - Wikipedia, the free encyclopedia. with modern CAD/CAM and make the casting molds with 3d printers and cnc machine should not be that difficult. Just a thought (i do that once and a while).
