    Hi all,

    I just bought an expansion pipe from a kawasaki kx65 dirt bike on ebay. I was wondering if anyone has modified one of these to fit a 67cc happy time. There are a couple of posts where people claimed they used it with good results but didnt give any info on how they matched the manifold up ect.. I'm assuming that somebody has played around with one of these since it is well matched to the 67cc and they are pretty cheap used ($15 for mine).

    Thanks,

    Torren
