ok, so i can order a part for any year and it will work?
Nope.
Look for your EPA decal on the air box. Some bikes had it on the sub frame/rear frame. It states this motor vech bla, bla, bla, meets EPA requirements for xx-xx model year. The Warrior had a couple of goofy runs Cali and Maine, NH models. Carb jetting and plastic colors should be the only differance in those.
If you can't find it, order 1997 or newer parts. 1997 was the first year of the round head lamps.
