Why is the motorcycle exhaust pipe smoking?

[MacGabriela]

There are three situations when a motorcycle exhaust pipe smokes: 1. The motorcycle emits white smoke: The temperature is not enough. After starting the engine, pay attention to the insulation of the water tank; 2. The motorcycle emits black smoke: The air-fuel mixture is too rich. Check if the air filter is clogged; 3. The motorcycle emits blue smoke: This is due to the engine oil level being too high. Check the engine oil condition promptly. A motorcycle is a two or three-wheeled vehicle driven by a gasoline engine, steered by handlebars, lightweight and flexible, capable of rapid movement, widely used for patrol, passenger and cargo transportation, and also as sports equipment. Motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.
