Definately if the carbs aren't in sync you will have some rough idling problems, but definately check for vacuum leaks first since that is easier to diagnos. Have you gone to your local bike shop to price out how much it would cost just to have the carbs synced? Would save you some time at least.

I know you also have to adjust the idle when the bike is totally warmed up otherwise your bike will jump up in rpms, I have an 81 that did this to me and all we had to do was finese with the idle screw everytime it would jump up in rpms while it warmed up until it was all warmed up and settled out, then problem was gone.
