Throttle Killing the motor?

[Charlie Foxtrot]

I pulled the bike out recently to get it ready for spring and the rest of summer and after I got it started the engine dies when the throttle is turned. I let the motor warm up for about 5 minutes or so and pushed the choke off all the way and when I went to turn the throttle it still happened. I was thinking there is something wrong with the choke or perhaps there is something else going on with it now, Any help with this would be greatly appreciated.
