You need to rebuild the carb and have all jets and ports cleaned, You can see a diagram at this link
Ok, well just turn the fuel/air screw all the way in lightly and back it out 2 turns, set the idle with the idle screw and then readjust the fuel/air 1/4 turn at a time until perfect, just test ride between initial settings and readjustment settings
The idle screw is #28 on the diagram I sent a link to earlier.
Fuel/Air is located at #14 on the diagram (you will need to remove a cap to make an adjustment here)
Since these setting are rarely ever off far enough to cause the symptoms that you posted, I would still recommend rebuilding.
Since the fuel/air is factory set and usually doesn't need adjusted, I would recommend just taking it in.

If old gas sat in the carb. for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb. for a full cleaning. Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb. fuel line that you take loose from the fuel tank. Let that set for say 1 or 2 days. then hook up the fueltank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb. and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws. Just take the carb. bowl off. Do not mix up any internal parts. It is best to work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps Fix Ya Up..
I would recheck for clog in fuel line. But if she has sat up for any time there will be dried gas in the line that once re-hydrates will continue to clog the inlet screen in the carb. Also you have one in the tank itself. The petcok will have a screen in it. Check these screens. If she can't get enough fuel she will not run up to speed.

It definately sounds like a pilot circuit in the carb is plugged up.. you must thoroughly clean the entire carb.
This requires removing
all jets and running a small wire through all orifices, spraying them with a
quality carb cleaner (Berrymans B12 is among the best) and blowing them out with
compressed air until all ports flow free. Also check your pitcock, and drain and flush your tank to rid any debris.
Good luck, i hope this helps.

Thanks, but bike has only 82 miles on it, and carb was just rebuilt because of clog in fuel line.
I think its low idle or fule/air adjustment. Mechanic who did it not a bike mechanic and likely didn't adjust correctly??
Can you tell me where the fuel/air and idle screws are? I tried to find picture of desciption on line. Bike is a 2007 200SE DR
Visible, or do I need to punch out a plug?
Thanks Again!
OK, I found the idle screw and sped up idle. Bike now runs on 1/2 to full choke.
Dies if turn choke off even after 5 minutes in 75 degree temps.
Should I try adjusting fuel/air, or just take to dealer. Anything else to check?
I carb was just rebuilt 10 miles ago! Another ideas (gas filter, settings etc), or should I just take it in?
OK, thanks for help. I'll accept your answer.

Solution was to take to dealer. Not happy, but it likely best he can do w/o seeing bike.
