I am putting a call out to all the Blue thumper folks. I picked up a pretty clean '99 YZ400F that has all the stuff to set up for dirt (stock), Ice racing (stock rims, ice tires and fenders) or Supermoto (17" rims on stock hubs). It is my first Blue Bike so I need some guidance. What are the weak links on the 400? What should I check during my tear down to grease everything and get to know the new toy? Known mods. 12.5:1 Wiesco piston. Hot start removed (can be put back) Durelle Suspension (lowered 2" for SM & ice) with extra Stock Shock. Polished and Ported Head. DSP full Exhaust. Ready to put on. Got Zip-Ty fuel screw. Got TM-Designs chain buffers & rollers to replace worn out stockers. Got Tag T2 top clamp and Pro-Tapers ready to go. I have read many pages of posts in the last few days, and I am going to check the Cam Chain, but other than that I do not see many problems with these bikes. Any advice on what to check would be GREAT.
