I'm the first to admit, suspension is probably my least knowledgeable area on a bike. I can change fork seals and bushing, and turn clickers and what not, but I don't have any experience with valving. I recently bought a racetech gold valve kit for my 06 YZ450F. I followed the directions, everything seemed to go alright. However now I have a problem with the forks. When the wheel comes off the ground (going off of a jump, heading through whoops, or even pulling a wheelie), the forks seem to extend very rapidly until they reach the fully extended point, where they seem to stop violently with a clunk. It is so bad that when I go off of a jump the forks extend and when they hit the end it pulls the front of the bike down (almost pulls the bars out of my hands). It is like there is no rebound damping or something. I'm figuring I must have put something together wrong, but any insight into what I should look at before I pull them apart would be great. Thanks guys.
