Cc = area of bore x stroke
Area of bore is pi (3.14) x radius (26mm) x radius (26mm)
= 2122.64 Sq mm
34 stroke x 2122.64 = 72,170 cubic mm. ÷10 (3 times because it's cubed, so ÷ 1000) = 72.17 cc

Calculate the Displacement of the Engine

A. Plug your measurements into the following formula.

____________ X ___________ X _____________ X .7854 = Displacement
bore measurement ---bore measurement---stroke measurement


52 x 52 x 34 x 1 (number of cylinders) x .7854 = 72.206
