Sounds like your carb needs a thorough cleaning. Remove the jets, and make sure they are clear. A guitar string and some compressed air works wonders.

Maybe. Check compression. Some folks have different ideas about carb cleaning. Did you remove the jets from the tet block and blow out the passages?

That usually is a sign of a plugged pilot jet. Where is the air screw at? If the carb is clean and the pilot is clean try adjusting the air screw.

My bike did this similar thing when I first got it. What I found that made the biggest difference was taking off the left KIPS cover and cleaning all the nasty gunk out then putting a new gasket on it. I had been mentioning my problems on here and was thinking that perhaps my carb jets were off. I used to have to run it with the air screw practically all the way in or with the choke on at all times. Now that I've cleaned that out it doesn't bog so bad when getting on the throttle. Whereas, before I had to flick the throttle non-stop until it was up and going. This may or may not be your problem. I'm just throwing an idea out there of something to check out, which is based on what I have experienced with my 89 KDX 200.

The problem the OP describes is a typical idle circuit clogged up/not functioning or fuel delivery issue. Make sure you have no air leaks anywhere (usual suspects are the carb to reed block boot, reed block spacer) and that the bike is in good condition (compression/leak down values good), and the petcock filter isn't plugged up (they have a tendency to collect crap, or sometimes break off altogether inside the tank. Easy check pull the fuel line off the carb, stick it in a jar and turn on the petcock, you should get a nice fat flow of fuel coming out. Then get a new plug, fresh fuel, clean air filter, and rerun the jetting procedures.
