What Causes Abnormal Noises in a Motorcycle Engine?
1 Answers
Motorcycle engines may produce abnormal noises due to the following reasons: 1. Inappropriate engine oil: If the oil viscosity is too high, it can lead to insufficient lubrication of the engine, causing friction. It is recommended that riders choose the right engine oil for their motorcycles during maintenance to avoid this issue. 2. Timing belt noise: If the timing belt tension is insufficient, prolonged use can cause the belt to stretch under excessive force, resulting in abnormal noises. This requires adjustment of the timing belt tension at a repair shop, or replacement if the issue is severe. 3. Incomplete fuel combustion: When poor-quality fuel is used, the engine may not operate properly. In such cases, it is necessary to refuel with high-quality gasoline.
