I bought an XR400 last year and it has been great, but I have been bottoming out, powering out etc. I just bought a brand new 2000 WR with a FMF powercore exhaust and protapers pre-installed. "Holy-Hell" are these bikes fast. We are all a bunch of lucky buggers! I guess I might get used to the power someday and want more, but I am overwhelmed for now.
