Spend some time at justkdx.dirtrider.net, and also check out this forum. Set the time frame for displaying posts in the Canadian Dave's Just KDX forum back several months.
pipes: ProCircuit platinum (chromed) or works (unpainted)
or FMF **** (better low end) or **** (better top end) (I'm forgetting which is which, the fatty or the gnarly)
reeds: carbon fiber high tension by FMF or Carbon Fiber
open up the air box inlet and rejet.
It's OK to keep the stock silencer.
The Gnarly Desert is the Rev (top end) pipe and the Gnarly Woods is the Torque (bottom end) pipe. they dont make the fatty anymore, which improved the whole powerband
Frankly, I think you should ride it for awhile and decide what you think it needs before you start throwing money at it. On my 99 220, I have left the engine and pipe stock, because the pipe is very quiet (although heavy), and provides very adequate power for tight woods riding. However, I have extensively modified the suspension and that did wonders for helping me go faster.
