I ordered a Fuel Mix Screw and Radiator Guards from Zip-Ty but it took them a long time to get here so I already got some other guards and a fuel adjuster. If anyone needs or wants either or both let me know by PM. Otherwise I'll put them up on Ebay. The Fuel Mix Screw fits all Keihin's and the guards are stamped for 00-03 YZ/WR 426/450's. The screw is still in the shrinkwrap and has instructions. The guards are new, not installed but they don't ship with instructions. Screw is $20 ($2 off) and guards are $60 ($5 off). I'll cover shipping if in 48 lower states.
