Something worth checking is to see if the intake boots (to the engine) are facing the correct way and are in good condition. At some point before I got to my bike somebody managed to put one boot on backwards. It took a bit to track that one down for me.I'm not horribly worried about it but i wouldn't hate it to go away either. I have my idle set for right at 1200 when shes warmed up. One thing i notice i still have to do though and I thought the carb refurb would have fixed was when I crank it over i have to have choke all the way on...and then even having it all the way on it will start and then idle down and shut down....no matter how warm it is out...its almost impossible for it to just start the bike and let it idle to warm up a little before leaving.
Also to check for vaccum leaks grab a spray bottle of water and when the engine is running spray at every possible place where there could be a leak. If the engine sucks in water it'll bog down.
