1 Answers
To adjust the mixture ratio of a motorcycle carburetor to the optimal state, follow these steps: 1. Warm-up: Start the engine and let it warm up for 3 to 5 minutes. 2. Reset: Fully reset the choke. 3. Adjust the idle speed limit screw: Turn the idle speed adjustment limit screw until the engine speed reaches 1500 to 2000 RPM. (If the vehicle does not have a tachometer, judge by feel—slightly higher than normal idle speed.) 4. Adjust the mixture adjustment screw: Slowly turn the mixture adjustment screw left or right until the engine speed is high and the operation is stable. 5. Adjust the idle screw: Adjust the idle screw to set the speed to 1000 to 1300 RPM.
