1 Answers
To adjust the carburetor mixture ratio on a motorcycle for optimal performance, follow these steps: Warm-up: Start the engine and let it warm up for 3 to 5 minutes. Reset: Fully reset the choke. Adjust the idle speed limit screw: Turn the idle speed adjustment screw until the engine speed reaches 1500 to 2000 RPM. (If the motorcycle does not have a tachometer, judge by feel—slightly higher than normal idle speed.) Adjust the mixture adjustment screw: Slowly turn the mixture adjustment screw left or right until the engine runs smoothly at a higher RPM. Adjust the idle screw: Adjust the idle screw to set the RPM between 1000 and 1300 RPM.
