Does it have real chokes or does it use mixture enrichening circuits? Bikes with mixture enrichening circuits can experience all kinds of problems if the lever that actuates the circuit does not close completely. Even a tiny bit of tension can cause the bike to die. The "choke" lever on the carbs must close positively. These types of carbs do not have choke plates that are connected to the cable.

If you have actual chokes then there could be an air leak somewhere.

Run over to the local parts store and get a can of starting spray. It's basically ether. Get the bike running and blast some spray around the intakes. If the bike responds by speeding up when you spray, it's sucking air and you need to fix that. If it doesn't spray a rag with the fluid and hold it over your mouth and nose till you pass out. It won't fix the bike, but you won't give a ****.

Dump the carbs and go to your local bike salvage yard and get some new-used ones. Bent needles on the carb slide are an indicator they're shot. Also, air leaks air leaks air leaks. Did I mention air leaks?
