Vacuum leak maybe?
My 2006 250 has an extremely hard time getting started when it is cold. When I do get it started I have to run the bike for about 15 min before the bike will idle. At this point the bike is hot and if I shut it off it I have to wait about 10 min before the bike will run again. I have cleaned the carbs twice now and have checked the vacuum lines and the vacuum diaphragm on the side of the carb for any holes. Don't know what else it could be, is there something in the carbs to look for that might be causing this?

Verify that your petcock is allowing the flow of 2 cc of gas per second into the bowls.
You may know that there is a little screen filter inside the supply hose, just by the carb, which needs to be clean. Twist the throttle half open when trying re-starting while hot and then, report back. Similar problem: http://www.ninjette.org/forums/showthread.php?t=151871

Have you adjusted the idle mixture screws, idle speed, and synced the carbs?

So i have adjusted the idle mixture screws but have not figured out exactly what to do to sync the carbs. The fuel is flowing fine and the half throttle warm start does not work. When i cleaned the carb i didnt pull the black caps on the top off. Bike is still having the same issues.

Did you clean the non-removable Choke jet pathway? Did you adjust your idle mix screws 2 1/2 turns out?
