Try leaning out the air screw by turning it counter clockwise a quarter turn at a time. If the air screw has no effect, install a leaner pilot jet and return the air screw to 1 turn out. Proper air screw settings are usually between 1 and 2 1/2 turns out.
In your carburetor. You have a main jet and an idle jet.
To adjust the idle on a KTM 450, locate the idle adjustment screw, typically found on the throttle body or near the carburetor. Start the engine and let it warm up, then turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. Aim for an idle speed that keeps the engine running smoothly without stalling. Always refer to the owner's manual for specific instructions related to your model.
If your KTM 300 won't idle, it could be due to a few common issues. First, check for a clogged fuel filter or a dirty carburetor, as these can restrict fuel flow. Additionally, inspect the idle adjustment screw and ensure it's set correctly. Lastly, a vacuum leak in the intake system might also prevent proper idling.

I would first look at the idle jet to make sure it is not clogged. If the idle jet is ok, it is either a bad spark plug (not likely but a cheap fix), the carburetor out of adjustment or a faulty ignition.
It would likely be one of the following:1) Clogged idle jet.2) Incorrect adjustment of adjusting screws on carb.3) Bad spark plug.4) Bad ignition system.

I have a Keihin-FCRMX 41 on my KTM (2007 525 XCW) and to adjust the idle you have 2 controls. The first being the adjusting wheel (black plastic knob on the side of the carb) and the other is the mixture control screw at the front of the float bowl on the bottom of the carb. 1) Warm up the engine 2)Turn the adjusting wheel to set normal idle speed at 1400-1500 rpm 3) Turn the mixture control screw slowly clockwise until idling speed starts to decrease. Memorize this position, and turn it counterclockwise until the idling speed decreases again. Now adjust the point of highest idle speed between these 2 points. 4) Now use the adjusting wheel to set the desired idle speed.
