from experience with the 229cc engine, id suggest these mods:
-supertrapp ids2 complete system($189)
-k&n filter w/outwear's($50)
-dynojet ket kit($35)
-cut the end of the snorkle off so its not just that small hole the size of a quarter.
-and maybe run it with the lid off if you live in dry conditions.
youll see a big gain in low end and mid range power, and some on top end too. youll be limited for top end though, since its shaft drive. but itll definitly give it more grunt with about a 3-6 hp increase.
