Im not trying to offend anyone here but how does the difference of a cylinder affect the power?. More CC= Power correct?

Bigger boom equals bigger power.

There is no replacement for displacement, is the old saw. That being said, a well tuned 72 motor will out power a poorly tuned 82 motor.

Sure size has an effect but with these little motors port timing is king. Most of the the large Taiwan bores have junk port timing. Also remember the motor was designed for 50cc so bigger cc requires more modification/porting to the block to take advantage of the extra displacement.

an old school trick is to match the crank to the bore.
