I have not ridden my bike for a while. When I went to start it I pulled out the choke and the bike started fine. Once it had warmed up sufficiently I pushed the choke in and the bike dies. I choked it again and it started, I can push the choke in part way and try and throttle, but the bike sputters and still dies when I push the choke in all the way. I pulled off the tank and drained all the gas, but still have the same problem. Any suggestions?
Check for an intake leak as suggested above. See here:

If it sat long enough, you may have trash/varnish in the carb. Suggest you drop the float bowl and clean that out. Pull the jets and clean them. Chase all the circuits with carb spray through the little red tube.
Take the accelerator pump apart and clean it out. Inspect the diaphram to make sure it is OK. Chase the port with carb spray.
Uncover the idle-air adjustment needle head if not already done, and remove it. Chase the port with carb spray. Replace the needle, carefully screwing it all the way in until it lightly seats. Then back out 2 1/2 turns.
Reassemble everything.
Pull the fuel hose off the carb and replace the hose (car part store). Before putting the new hose back on the carb, stick the end in a clear jar and open the petcock (if a vacuum operated one, you will have to apply suction on the vacuum hose). Drain about a cup of gas from the tank and inspect it for debrix or water. If necessary, clean the tank again.
Start the engine and warm it up until the valve covers are warm to the touch. Increase the rpm to around 1,200rpm and lock the throttle there. Adjust the idle-air mixture needle until you get maximum rpm, then back off about 1/4 turn. If adjusting the needle out makes no difference, the slow jet is too large. If you can adjust the needle all the way in to the seat with no difference, the slow jet is too small.
Let us know what you find.
