wr vs yzf jetting

Hi, i want to know what is the standard jetting for a wr400 2000 and a yzf426 2000, which needle and clip, jets, etc.

Thank you.


'00WR 400


OBDRS - #3 (3rd from top)




OBEKR - #4 (4th from top)



Thank you, if i put a yz carb in a wr, should i replace the needle and the main jet with the stock or i can stay with the whole yz carb????


Stay with the YZ carburetor and E-taper needles.. :)
