help finding accurate cc?

[ks_2k_blast]

i borred my blaster 1mm over, but im not sure how to figure out how many cc's it is now. stock stroke. just borred. my friend said probly 220 cc now, but that sounds a litte high. anyone know how i can get an accurate size?

your friend was way off lol 1mm over is about 201cc

i would have guessed around 205ish. looks like i was off a ways too. lol. thanks. just didnt make sence to me that one out of 67 mms would add 20 ccs.

c'mon guys this is asked all the freakin time

(bore/2)^2*pi*stroke

sooooooooooooo stock bore is 66mm and stock stroke is 57mm

(67/2)^2*pi*57=200.86cc
