It's pretty easy actually. If you are comfortable removing the gas tank yourself, you can synch the carbs yourself. Takes me about 20-30 mins to sych my carbs 5-10minutes of that is warming the bike up.
The hardest part is delivering fuel to the carburetors with the tank off. They sell external fuel tanks kinda like an IV bag at a hospital) that you can hang somewhere to keep the carbs filled. I usually just remove the tank to adjust the left screw, hook the tank back up to fill the bowls. Remove tank and synch the right screw. Reattach tank, fill bowls, remove tank, synch middle screw. Reattach tank and drive away on "new" bike.
