You dont need pics - simple once you remove Carb:
Need to know all about the ZYP ty fuel screw and Pics on how and where it goes would be very Helpful!!
It is on the under side of the float bowl right hand side - out of view normally.
The stock carb comes with a screw that is blanked off (hidden from outside adjustment) with an allow plug with a small hole. This plug must be removed as your new screw is long enough to prottrude through this hole so you can get adjust by fingers - clever
You may also have to drill the carb hole to a slightly larger Diam. so the thread of your New Fuel Screw will slide in. My Sudco part fitted fine..
The only way I could get my alloy plug out was:
1. Remove Carb
2. Remove float bowl
3. Punch out alloy plug (carefully)
4. Remove stock fuel screw (keep parts: spring and O -ring)
5. Install new fuel screw (with spring and O -ring)
I would recommend also rejetting and giving the Carb a clean at the same time.

Lay a white rag under your work area to catch them if they fall.
Also, If you want to remove the fuel screw access plug while the bowl is still on the carb use a set of picks. It'll pop right out. The carb will need slid out of the engine boot and rotated a little.

my new fuel screw. I will attach a photo of it. Its made of stainless steel, it has an additional "o-ring" which keeps out dirt and also helps "support" the extended screw and keeps it from working its way out. The knob had "one" nub thats a little different (pointed) so you can have an idea how for you turned it in or out by feel..... give me your thoughts (for those who have used this screw or would like to)
Great idea, when I fitted my Sudco (good stuff BRASS - dont like the alum ones) I felt it needed some support/sealing around the shaft just before it exits the float bowl - it even has a groove for an O-ring which was not fitted.
Problem with mine is that every half revolution the screw looks the same - countless times I have "backed" it out and got lost counting the Half revs... pain in the butt!
I think I'll go for a replacement like yours - likewise, gloved hands are hard to fit past the starter motor...
BTW, 06 WR 450 has FCR 39, same as 05WR and KTM 450, BINGO
Thanks for the info
