Why Does a Motorcycle Stall When Accelerating in Cold Weather?

[SanCharlotte]

During the initial idle period after starting, the carburetor only supplies combustible air-fuel mixture to the cylinder head through the idle jet to maintain stable idling, while the main jet is blocked by the needle valve. When riding begins, opening the throttle increases the air intake suddenly, making the air-fuel mixture in the cylinder head too lean. This causes the engine's combustible mixture to fail to burn continuously for a short time, resulting in the symptom of being unable to gain speed. Once the needle valve moves upward and the main jet starts working, the air-fuel mixture gradually returns to normal, and the symptom of being unable to gain speed disappears. Here is some relevant information about motorcycles: Introduction: A motorcycle is a two- or three-wheeled vehicle powered by a gasoline engine and steered by handlebars. It is lightweight, agile, and fast, widely used for patrols, passenger and cargo transportation, and also as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. Development: The development of motorcycles is like climbing a staircase, with each step representing a higher level of advancement.
