What causes unstable idle speed in motorcycles, fluctuating up and down?

The reasons for unstable idle speed in motorcycles, fluctuating up and down: 1. The ignition system, ignition coil, or high-voltage coil has minor damage. In this case, although the vehicle can start, it may exhibit unstable idle speed similar to a carburetor malfunction; 2. There is air leakage at the connection between the engine and the carburetor, or cylinder leakage; 3. Incorrect spark plug electrode gap or other wear or damage; 4. The idle jet in the carburetor is blocked, or the mixture ratio and idle adjustment are incorrect. Idle speed refers to the engine running without load, only overcoming the frictional resistance of its internal components, without delivering external power. The minimum speed required to maintain stable engine operation is called idle speed, which is one of the basic operating conditions of the engine.
