I just got a great deal on a YZ426 tank, shrouds and seat on Craigslist for $65. I put it all on the bike today and everything fit perfect except for the lowest screw on the shroud where it should screw into the radiator. The angle of the screw hole is way off. Are YZ & WR shrouds different or is it the radiators? My stock shrouds fit fine, but are just beat up.
