Pitbull - all of them (mods). I would say 99% of us ride woods, the bikes aren't really suitable for MX.
If you can afford it, get another pipe - check out the kdx pages for comparisons between the FMF torque & rev (the stock weigh a ton as well as making the bike feel constipated).
The air box lid is free & easy to do (so why the heck did I wait so long?), and on the 200 I felt like it had heaps more bottom end - it just tractored up hills.
Get rid of the stock bars, they're cheese & will bend if you look the wrong way at them. Get the jetting sorted out, if you need help, ask, someone will probably be able to help, but again, the kdx pages have great tips there.
Put in boyesen reeds (I did this same time as changing pipe, so not 100% sure of the difference, but again I think it gives more bottom end).
It all depends on your budget & if you're buying 2nd hand some, if not all, of the mods will be done.
Good luck
