I have heard a lot of talk about taking the air box lid off and that sort of thing. When I got my bike, it already had the air box lid removed. I have a lot of jetting problems and think this may be part of the problem. Plus, I am seeing some water and dirt in the air box that I am not liking. I would like to either get another lid and put it on, or fabricate my own. I have never seen a KDX with the lid on though, so I'm not sure how the original setup is supposed to look/act. If anyone has a picture of the air box with the lid on, I would greatly appreciate a look-see. Any other info is greatly appreciated too! My e-mail address is randolphja@aol.com.
