What Causes Abnormal Noise When Accelerating a Motorcycle?

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.

What is the method for a car to pass over a speed bump?

Car passing over a speed bump method is: before passing over the speed bump, reduce the speed, and pass slowly with both wheels vertically. This method allows both left and right wheels to contract simultaneously, and the force from the ground is equally shared by the springs and shock absorbers of both wheels. Even force distribution can minimize damage to the car. The wrong practices for a car passing over a speed bump are: 1. Passing over the speed bump with only one side of the tires; 2. Passing over the speed bump at high speed; 3. Passing over the speed bump diagonally. Speed bumps, also known as speed humps, are traffic safety devices installed on roads to reduce the speed of motor vehicles and non-motor vehicles.
