1981 KZ1300 A3 carbs

I was having the same issue accessing the mixture screws and brought a purpose made long , thin screwdriver which enables you to get on the screws although number 3 cylinder is properly fiddly you can do it although it is almost by feel

As this seems to be a general A3 carb thread,  how in the hell do you adjust the mixture  screws when you can't get a screwdriver in there, being blocked by the choke rod mounts?

Correction:  "The generally accepted setting for the Pilot-Screws" is 3 - 3.5 turns out.  IN leans the fuel/air mixture - OUT richens.  This setting will also influence the "Transition" ports (3).

My thoughts must have been in transition: - The pilot-screw setting has NO affect on the Transition Ports !
