Why does the motorcycle jerk when accelerating?

[Carson]

Motorcycle jerking during acceleration is caused by intermittent ignition or a clogged carburetor. Here are detailed explanations about the carburetor: 1. Introduction: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine operation. As a precise mechanical device, it utilizes the kinetic energy of the incoming airflow to atomize the gasoline. Its crucial role for the engine can be likened to the "heart" of the engine. A complete carburetor assembly should include starting device, idle device, medium load device, full load device, and acceleration device. 2. Classification: Carburetors are divided into simple carburetors and complex carburetors. They can also be categorized as downdraft type and side draft type. From the perspective of throttle type, carburetors can be further classified into rotary type and lift type.
