How do you adjust the idle on a KTM?

Answer 1

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.
