03 WR450F jetting VS 03 YZ450F jetting

Does anybody know if the 03 WR450F comes from the factory with the same carb jetting, needles and screw turns as the YZ450F?

If they are not the same, does anyone have the YZ specs?

i'd have to say no. if they did than the wr guys wouldn't be going out and getting yz needles
