What are the symptoms of a loose motorcycle timing chain?

[VonArthur]

It causes noticeable abnormal noise and accelerates the wear of timing gears and other components. Here are the detailed explanations of related content: Chain failure: If the timing chain of a motorcycle becomes excessively stretched, it will produce noticeable abnormal noise and accelerate the wear of timing gears and other parts. In severe cases, the timing chain may detach, skip teeth, or damage valves, pistons, and other components, leading to serious malfunctions. Timing chain tensioner: It automatically adjusts tension. If the chain stretches, it will automatically compensate. When abnormal noise occurs, first check the chain's tightness and the condition of the tensioner. If the tensioner has extended to its maximum length, the timing chain should be replaced promptly to prevent further damage and more significant losses.
