As soon as I start my bikes I knock the choke off to between 1000-1500 revs otherwise they do gallop away a bit, not what your wanting on a cold engine, I don't ride them with any choke once they have idled for a few mins just kill the choke and take off, chances are it will stall from having choke than without at that stage.
I had problems with my Sprint recently running on two, the problem would come and go, I had the carbs and air filter off twice doing this and that but ended up cleaning the whole fuel system... tank flush and seal, fuel tap rebuild, inline fuel filters fitted, witches hat filters at the carb fuel hose unions removed, carbs cleaned, two new HT leads..they looked fine but on closer inspection wouldn't clip home securely to the plug, I had already fitted a K&N new plugs etc a while back...oh and just for good measure a thicker vac hose fitted and re-routed & coil contacts cleaned..!
It worked and is now running fine, my next move would have been coils, pick up contact for the crank..basically the leccy gremlins that might be at play.
Bottom line is as your probably aware it's a process of elimination, but if you have the carbs off don't skimp, do everything you can while at that stage, it's a pain to keep pulling them.
Quick fix in the interim if your lucky may just to be run some RedX at double strength and see if it clears allowing you a bit less urgency for your maintenance ;-)
