( π ) (37^2) * (65.5) = ( π ) (1369) * (65.5) = ( π )*89669.5= 281075.0425 mm^3
divide by 1000 to convert to cc so 281075.0425/1000= 281.0750425cc
so there ya go, offcially the displacement is 281.07 cc

rob, that formula seems incredibly complicated, but as i was reading it, i realized something, it's basic math. all ur doing is finding the area of a cylinder. ne ways, if u have a bore of 74mm and u wanted to order a piston, u would order a 74mm piston, right?
