the carb is pretty good, not much point in upgrading it IMO, maybe bore it if you really wants,
motor wise, mods worth doing are, pipe and muffler, but most of them got sold new with them,
a rad valve, (or a v force if they do them) would be the only thing worth doing,
in the end of the day, i would not do anything to it, just ride it, if you want something faster/newer better handling, then get a newer KTM/Gas GAs beta etc,
if you really want a good mod and a project, find a late model 250F thats blown up, and change the kdx motor into one of those,
04-05 KX250F and 04-06 RMZ250's are the easiest as steel frame, alot easier to mod than the alloy ones,
