2005 Wr450 Mods List
Posted March 31, 2005 - 08:04 PM
My '05 WR250F came with a 168 main, I'm running a 180 and went one step richer on the needle number. I did go to a YZ pipe and opened the side of the airbox, but that shouldn't have been good for more than a 175 if it wasn't jetted so lean from the factory.

The mods create no problems, unless you expect a dealer to honor a warranty on the bike... you can "undo" some of the mods if that is the case
