What Causes Abnormal Noise When Accelerating a Motorcycle?
1 Answers
Abnormal noise when accelerating a motorcycle is usually caused by excessive valve clearance or loose components. Here are specific solutions: 1. Excessive valve clearance: The noise during acceleration is caused by excessive valve clearance, which can be resolved by readjusting the valve clearance. A "clanking" sound under load during acceleration may result from poor-quality gasoline or a lean air-fuel mixture due to insufficient fuel supply from the carburetor. This can be fixed by using standard gasoline and cleaning the carburetor. 2. Loose components: If the noise is due to loose parts, it is advisable to have the motorcycle inspected and repaired at a service center to prevent minor issues from escalating into major accidents, thereby reducing potential economic losses.
