[LeCaleb]

Motorcycle engine abnormal noises are caused by excessive valve clearance and a stretched timing chain. An engine is not only applicable as a power generation device but can also refer to the entire machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc. A motorcycle is a two or three-wheeled vehicle driven by a gasoline engine, steered by handlebars to control the front wheel, known for its lightweight, agility, and high speed, widely used for patrol, passenger and cargo transportation, and also serves as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, tourers, etc.
