Yeah brother!! I have a 02 KDX 220 and I am just wrapping up all of the same mods you speak of. I just got my carb back from RB today and wow, if it runs as good as it looks I'm in there! The only difference between our 2 bikes it sounds to me is that I went with Carbon Tech reeds because of the advice of a close friend who races GP 125/250 and uses them. It seems unbelievabel to me that my bike will run close to a 250 motocrosser, because it is a dog out of the box. My only goal in doing all of the mods was to duplicate the performance envelope of my friends bone stock 1998 KDX 200. From what I am hearing, it sounds like I have more than succeeded. I will know in a week or two. Thanks for the great post!
