i'm thinking the needle that was in there,has been banging around enough to wear down,causing a rich condition. my 01 carb was one of the first anyone had heard of that had worn the jet needle oval and suggested jetting was way to rich across the board. jet the bike to work the way you want, and forget what #s the jets and needles are. once the pwk is a few years old, you have to go freelance/and jet to what the engine wants.
