    I have built a few of the "Chinese" gas bikes. I still drive one ten miles one way to work. I am ok with them but would like to try something different. I have a 1943 1/2 hp WMB (washing machine Briggs). The old kick start kind. I had it on a skate board when I was a kid. Lots of fun.

    I don't know if there is a cubic inch to horse power converter. Does any one know a formula? Or maybe Since there is a rule on 49cc or less there is one on horespower too?

    I am pretty decent on making things run but very slow on shopping for information on the net.... I'm not as caught up on the "information age" as I would like to be.

    Can anyone help me? I much appreciate the help this forum has given my on mike bikes.......you all have kept me running!

    Your engines horse power is not really dictated by it's cubic displacement as much as other factors.

    I think that engine you have is about 5/8th hp.
