Got my hands on 2 WR450F carbs and while waiting for them to show up, I am gonna order some jets. I need to know what the stock jetting is so I don't get repete jets... Does anyone know all the settings and sizes of the jets including the needle? They are 05s, were the 04-06 all jetted the same? Thanks for the help.....

06 450F STD Jetting
Common changed items:

MJ 165
PJ 45
Starter 65
Leak 50

The PAJ in the intake bell is not normally changed out unless you mess with the ACV. Then the part is for a YZ, not listed under WR.
