Main Jet: 170
Pilot Jet: 48
Fuel screw: 2 out (about)
Needle model/Clip position: 04 WR 4th pos stock 05-06 is fine
Starter Jet: 70
Leak Jet: 40 (50 is stock)
Accelerator pump cover: Icing on the cake
AIS: Mark Lowe's Smog removal kit, more Icing

I'll stop there since you said you've done the standard mods. I'm assuming you live and ride in the lower AZ desert areas.

He probably has a boyesen cover, not a free mod.
accelerator pump is on the bottom of the carby, take your fuel bowl off and you will see it. it is only small, it injects a fuel squirt when you turn the throttle. boyesen cover justs puts fuel in it quicker, and eliminates any quick throttle bog that you cant solve through jetting changes.
