I have a 99 WR400 and am looking for anyone that has purchased and installed a RevLoc clutch. I hear that they are excellent for mountain riding. Any comments? Also, I'm looking for stock YZ 400-426 tank to replace my large tank. I need to get up on the front of the bike. Any used ones out there someone wants to part with? One more thing, Where can I get a slightly softer seat for my WR?
