Remove Seat
Remove Tank (draining fuel makes handling the tank much easier)
Loosen clamps on front of carbs
If your machine is older, and how old I can't say, but the rear carb boots may be pretty stiff if older. Warm boots with blowdryer to help.
Remove choke cable at the carbs.
I agree it may be easier to remove throttle cables at handlebar but I've done it at the carbs a few times. If you remove at the bars, take a few pics of how they are routed and connected to the throttle.
Eyeball your water pipe connections to the rear of the cylinders for leakage. If your bike is older (age?) you may want to replace those o-rings too while the carbs are out. I've got to go back in to replace mine and I'm foolish for not doing it while carbs were out, but my bike is an 87.
