I found the bike I have been looking for and I am picking it up soon. 2000 WR 400 With Hotcams, GYTR Carbon ex, Scotts Steering stabelizer and a bunch of other stuff. I had a couple of questions. What should I look for when picking it up? What are the first things should do when I get it home? What can I do to help increase the bottom end power? Has anyone gone with bigger Valves? Does Kipple White make them? Has anyone ever used the Carbon Fiber airbox and did it help anything or just look really cool? Does the 2000 WR400 have a high speed compression adjuster? That should be enough questions for now. Thanks!
