Why Does a Motorcycle Experience Unstable Idling?
1 Answers
There are several main reasons why a motorcycle may experience unstable idling: 1. Carburetor: If the carburetor has not been cleaned for a long time, it can lead to unstable idling. 2. Engine Air Leak: A slight air leak in the engine can also cause unstable idling. The causes of air leaks can vary, such as overly tight valve clearance, poor sealing between the carburetor and cylinder block, or damage to the secondary combustion tube, all of which can result in engine air leaks. 3. Ignition System: If the ignition system is slightly damaged, the vehicle may still start but exhibit unstable idling symptoms similar to those caused by carburetor issues.
