    how much power?

    i had my engine apart to change the gaskets and while i was at it i measured my piston because i was told by the old owner it was bored out to 300cc. it measuers out to 2 5/8 inches witch is almost 67 mm. stock is 47 mm i believe. so that makes it almost 20mm over. how much power did it gain? i dont know a whole lot about how many hp is in a certin amount of cc.
    down to parts because i no longer have a place to ride trikes.

    GIT IT RAAAGGGGG !!!!

    there is no set amount of power per cc.not rel sure if thats what your asking,but a poorly tuned 300 r cooled air could make less power then a finely tuned one.

    true i was just wondering how much hp my bored 200 was giving out. but i can tell you 1 think you can tell its bored. when it cold out it runs like crap till she gets warmed up. then it takes off like no tommarow.

    If its on a 200 honda trike, stock bore is 65mm max is 67mm which only brings it to liike 198cc . You wont feel the difference in power.
