You may have some trouble without buying a kit for changing the vacuum signal hole diameters. There are some really good kits out there and I recommend you talk to the suppliers or manufactures about all motor/exhaust mods and altitude/ temp ranges you operate in. They will get your kit really close. Probably $100- $130. Make sure no vacuum leaks at carb holders/ manifolds, plugged low speed jets.

Also helpful - when did this start happening? Has it always happened or was it something that just recently started occurring?
The main and pilot jets are removed through the float bowl. The main jet needle is removed with the slide from the top of the carb. You will have to pull the slides out to find out which clip the needle is set to. I had to drill 3 or 4 screws out when I tried to remove my needles just recently, just fyi. I have found all the screw heads in my carbs to be pretty soft.
Others will be able to provide better specifics, I'm sure.

If you are looking for the main jet, you are on the wrong end of the carb.
To remove the throttle link bar, there is a bolt at the front of the slide assembly (engine side) under the cap on each carberator as well as a bolt in the push/pull mount between carbs 2&3. Once these five 8mm headed bolts are removed the bar just slides out the side.
One the bar is removed the slides can be pulled straight out (although the gaskets will likely be in the way - you may need new ones).
The screws you mentioned are down inside the slides and the e-clip on the needle is sandwiched between the plate these screws are holding down and the bottom of the slide.

...kz900. air pods, Kerker header. im wanting to remove my jets. first to see what size they are. second to see where the clip is set at. it is bogging down when i punch it from a stop. its pretty bad...If anybody might have any ideas on the bog down im all ears
Sometimes non-carb related issues may contribute to bogging down when punched from a stop, such as incorrect valve clearances, weak ignition instead of healthy properly timed spark, sticking advancer, etc.
Have oem points been replaced with electronic ignition such as Dyna-S?
If not already done, would use strobe type timing light to verify proper functioning of advancer by watching it instantly move back and forth as rpm's are varied by blipping the throttle.
Might also be caused by maladjustment of pilot air screws.
Am not particularly suspicious of the jet needle clip position on KZ900 oem carbs, especially with tan color plug reading.
Would be more suspicious of possible pilot circuit issues.
Good Luck!
