That's been SOP for me in car inspections here in Delaware.
I used to swap carb's for inspection in my Mustang.
Luckily, bikes are a little easier here...all the lights on the bike have to work, must have a chain guard, and exhaust 95dB or under.
Ok, basically lie my ass off, lean her just for the test and get the hell out of there to put her back where she likes it.... :laugh:

I lived in phoenix from 95 until 03. I passed the emissions with wilder engine tune set ups than what you have listed.
I always do a idle drop test . none of the other jets matter beyond the pilot jet and mixture screw adjustment. go fat until the idle drops - then go lean until the same thing happens just a little drop in the idle speed. go exactly half way from the two settings you have just found and that is optimal for performance at the present conditions. (co = 3 maybe) ( hc will go up with too low of idle)
go lean a half turn on all 4 carbs, keep the idle at/around 1000 - take the test - re idle drop and ride til next year
if you get longer duration camshafts I'd advance the ignition timing 3 or 5 degrees at idle.( for the test only )
get the idle to go up and down with all 4 fuel/air screws first and when done with all 4 , re-adjust with the final idle speed with the adjustment finger screw. after a couple times it is a snap just hard to write and describe.
