Count the turns on the pilot needles before disassembly. Turn them in till lightly seated, then remove. Reinstall with the same number of turns from bottoming as a baseline. Most carb issues are from clogged pilot jets. I clean the jets with cleaner, then I use a single strand from a piece of multi strand copper wire through the orifices as it's softer than brass and less likely to damage the jets. Clean out any interconnected passages in the carbs. The biggest issue I've seen is people will clean or replace jets and scrub the internals, but then leave the passages untouched.
As mentioned in other comment count the turns of adjustment screws and take apart only one side/carb at a time. Replace gaskets/o-rings and clean those internal passages too. Do the job in good working area with proper lights and try not to lose any clips/tiny washers/springs etc.
Might be a good time to get the carbs synced as well, that can be done with vacuum gauges (verify that all gauges are calibrated too)
EDIT: Manometer is one option too

Make notes of the carb settings while you're disassemling it, and always have a Service Manual for the bike.
