I've got a new machine that's very similar to the Yamoto / Redcat / Kazuma machine that we'd like to start doing some mods on. Has anyone gone down that road yet?

Not intended for MX, but maybe some GNCC racing. Looking to upgrade shocks to maybe Works, and definitely install a pipe, carb, and cam. Do these machines cross over to older Honda stuff? Anyone have any recommendations for who sells go-fast parts?
