08 300xc project/advice

[matthoyda]

I recently purchased an 08 ktm 300xc (all stock with 11 hours). Cleaner than most brand new bikes I have bought. My plans are to make the bike capable of motocross and gncc style woods riding. I believe I have started with a good platform, but I was wondering if there are any set ups that work really well or what doesn't work so well? Also what will help out with the power going flat on top end?

Thanks, Matt

_{Respring the suspension for your weight, if you want more, have them revalved.  For the engine I prefer the red power valve spring, about one turn inwards.  Others prefer the green or yellow.  It only takes a few minutes to change, so try them all and pick the one you like.   After proper jetting, try a head mod where the squish band is optimized.  The cost is about $60.  Also swapping the CDI with one form a SX model will give you more snap.}

Any exhaust options make a big difference?
