Displacement is: Piston area multiplied by the stroke,for small engines usually expressed in cubic centimeters or cc.,one cc equals 0.061 cubic inches,or one cubic inch equals 16.4 cc. One cc. is one thousands of a liter.For instance a 50 cc. engine has close to 3 cubic inch displacement (50/16.4 ) or 0.05 liter.Typically an engine produces around 0.05 HP per cc.
Yeah, I was gonna keep my mouth shut but I want to warn everyone again,
DON'T BUY ANYTHING FROM BRYAN AT REVOLUTIONCYCLES!!!!!
He offers stuff for sale that he does'nt even have in stock and then sends out smaller motors hoping no one will notice.
Reminds me of some dirtbag hippie on the street slangin fake doses, just to make a buck.
bore times bore times stroke times .7854= displacement so bore being across the cylinder , stroke from crown of piston from the piston being all the way at the bottom and how far it travels up to top dead center some precision tools are needed but it can be done with simple tools it just wont be as accurate but very close depending on your ability and how you do it,if you do your measurements in inches you can convert your final number to centimeters by multiplying it by 16.39 then your inches will be centimeters
