C m = 0.166 x L x N. Where: C m is mean piston speed, in feet per minute. L is stroke, in inches. N is crankshaft speed, in revolutions per minute. Thus, using again the Kawasaki F-5 engine as an example, with L being 2.68-inches and N given as 9000, we find that. Cm = 0.166 x 2.68 x 9000. Cm = 4000 ft/min.
