What Causes a Motorcycle to Have No Idle and Easily Stall?

[McAlan]

Motorcycle having no idle and easily stalling can be caused by the following reasons: 1. Fuel line blockage: Possible clogging, spark plug carbon buildup may prevent normal operation. Check the fuel line and inspect the spark plug for carbon deposits. 2. Carburetor mixture too lean: To meet Euro 2 standards, manufacturers often set the mixture ratio very lean before leaving the factory. However, the mixture ratio must be readjusted to normal before actual use. With the correct mixture ratio, your motorcycle will start more easily. 3. Valve clearance: The valves may not be fully broken in, causing slight leakage, so adjusting the idle speed higher can prevent stalling. If the valves are too tight and leaking, starting will also be difficult. It's best to adjust the valve clearance. The engine valve clearance may be slightly too small, and the ignition system may experience slight leakage due to high temperatures.
