I just picked up a 2003 WR450 that had a bit of a fuel leak when I bought it. after getting it home to troubleshoot it, I figured out that I have fluidyne radiators and a tank from a 2005 WR according to the markings on it. the 05 tank (2.6 gal) was not a good combination with the aftermarket radiators since it was melted on both sides, obviously creating a fuel leakage problem. so I purchased a 2003 tank (2.1 gal) which fits a nice distance away from my radiators. the problem is my radiator shrouds don't fit the 03 tank properly, nor does my seat. so my question is, are the seats and shrouds from an 03 different from other years? I'm just curious for an answer on here first before I go searching for replacements that may or may not fit properly. thanks in advance for any advice.
