What Causes the Abnormal Noise When Releasing the Throttle on a Motorcycle?
1 Answers
Abnormal noise when releasing the throttle on a motorcycle may be caused by improper tension of the drive chain or lack of lubrication. Below is relevant information about motorcycles: Types of motorcycle licenses: Currently, there are three types of motorcycle licenses in China—F, E, and D. License F only permits the operation of mopeds with engine displacements below 50CC, but this type of license is rarely pursued. License E allows the operation of any two-wheeled motorcycle without displacement restrictions. License D permits the operation of all two-wheeled and three-wheeled motorcycles. Therefore, holding an E license enables the operation of all two-wheeled motorcycles, as there is no separate license for large-displacement motorcycles. Concept of motorcycles: A motorcycle is a two-wheeled or three-wheeled vehicle powered by a gasoline engine, steered by handlebars to control the front wheel. It is lightweight, flexible, fast, and widely used for patrol, passenger and cargo transport, as well as a sports equipment.
