What causes a motorcycle to stall when giving it gas?

[DiMiranda]

Reasons why a motorcycle stalls when giving it gas: 1. During the idle period just after starting, the carburetor only supplies combustible mixture to the cylinder head through the idle jet to maintain stable idling. This is caused by the main jet being blocked by the needle. When the needle moves up, the main jet starts working, gradually restoring the mixture to normal conditions; 2. When the throttle is increased, the intake air volume instantly increases, making the mixture in the cylinder head too lean, which prevents the engine's combustible mixture from burning continuously in a short time. A motorcycle is a two- or three-wheeled vehicle driven by a gasoline engine and steered by handlebars. It is lightweight, flexible, fast, and widely used for patrol, passenger and cargo transportation, as well as a sports equipment.
