Get yourself some nozzle cleaner pokey bits of various diameters, pull the carbs and poke out blocked jets, dont go mad cos you don't want to make the the holes bigger (they are soft brass) but you do want to remove any varnish, I find brake cleaner etc wont remove all the varnish that makes the tiny orrifice smaller, you can feel the difference between poking varnish crud and solid brass.
Get some brake cleaner with a straw and ideally compressed air to blow out the passages in carb body.
With the carbs off and cleaned, you can sort of "bench sync" them by getting the butterflies to be all the same, you can do it by eye but they will be miles out, you can blow through each throat with your mouth and feel the difference, then when they're on the bike they will be fairly close. When syncing you have to be very carefull to change one thing at a time and you need to know all jets are clean and pilots set exacly the same, dont re adjust pilots untill vaccume is synced.
