Anyone try this ? Isn't a 2000 cr250 carb a 38mm pwk ? Part # 16100-KZ3-J21. My PWK from amazon arrived today and it was a cheap knock off so Im sending it back and I need to order one asap..I figured I could get a used one from a 2000 cr250 since i think its a pwk..let me know guys if this will work or what other year bikes had pwk's I can look for used.
