2005 650 V star won't idle

Absolutely not, the automatic choke is defective. Replace that and it should be fine. It will need to be adjusted when cold to fully closed position. Check vacuum lines as vacum pulls the choke back when engine is started.

you eather have bad gas or the carb has astoped jet

when the choke is fully closed your choking the fuel out,, thats why when you give i t gas it dies , its not supposed to run with the choke on and getting fuel , use the choke only until the motor warms up to operating temp,, then open it,, and you should be fine,

Has the bike been parked for two weeks or more? If so, the fuel has most likely gummed up and plugged fuel passages and jets. Might try adding 1/2 to full can of SeaFoam to existing fuel in the tank, crank the bike and run (with choke if you have to) at a high idle for several minutes. Shut it down and let set for an hour or so allowing the SeaFoam to work. Start bike again and run at high idle again, trying to run it without the choke. If this doesn't work, then the carb probablyneeds a tear down and a manuel cleaning and reset.

You can try a good fuel additive such as "Seafoam" . Put it in the tank. The more the better to "clean out the carbs". Start her up and let it do it's thing. Let it just idle for a while and try to open the choke. If this does not do the trick. Then you will need to remove the carbs and take them apart and clean them-sorry. When you think you are going to let her set up for 2-3 months, run some Sty-byl fuel additive in your gas. 

Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck
