what would be the best thing to do to an 02 400ex besides exhaust, jet kit, and air filter

Sprocket, suspension, tires depends what your going to be doing on it.

Ditto,

I put a K&N w/ outerwears, cut the lid box, jetted, and a tooth on my sprocket on this weekend... It really woke the bike up, I always felt like i ran out of power way to soon, but now i have more power all the way through the RPMs. Next is a FULL exhaust, but what i did this weekend was enough to put a smile back on my face for a little while.
