Hey keist08-
Did you figure out what is wrong with your quad? I am asking because I have a 02 Warrior with the same EXACT problem. I just finished swapping the coil assembly with our other warrior but that was not the problem either. I am going to change the plug tomorrow and see if that helps. I think that was already tried though. If you figured out what it was could you please let me know? If you are still having a problem and I get it I will drop you a note.
