What causes unstable idling and easy stalling when a motorcycle is warm?
1 Answers
The reasons for unstable idling and easy stalling when a motorcycle is warm are as follows: 1. Low idle speed: Check if the idle speed is set too low, as an excessively low idle speed can cause unstable idling and easy stalling. 2. Carburetor mixture too lean: Since current motorcycles must meet Euro 2 standards, manufacturers often set the mixture ratio very lean before leaving the factory to comply with the standards. However, the mixture ratio must be readjusted to normal before actual use. 3. Spark plug failure: The spark plug on the engine is a wearable part that needs regular replacement. If the spark plug is used for a long time, the electrode gap will increase, affecting the spark plug's ignition. Prolonged use can also cause carbon buildup on the electrodes, which further impacts the spark plug's ignition.
