look it up lol :p . if you want to figure it out use PLANK/33,000. P=average effective pressure, L=length of stroke, A=area of the top of a piston in square inches, N=number of power strokes in each minute, K=amount of cylinders.

no problem. forgot to mention that i believe the L/stroke needs to be converted to feet.

ex- according to yamaha, the stroke on a 2010 yz250f is 53.6mm 53.6/25.4=2.11/12= .176 feet.

edit: oops, i don't know why i thought you had a yzf lol. oh well, same concept. just look up the stroke for a kx.
