Motorcycle consists of five parts: engine, transmission system, running system, steering, braking system and electrical equipment. The overall structure of motorcycle and the names of its components.

Carburetor is an important part of motorcycle fuel supply system, which is located between air filter and engine intake. Motorcycle engines generally adopt carburetor, plunger and float chamber throttle valves with horizontal intake flow direction. The carburetor structure mainly consists of a float chamber and a mixing chamber.

Extended data:

By turning the throttle handle of motorcycle to drive the throttle steel wire to hang the rope, the throttle valve and the fuel injection needle are controlled to move up and down, and the cross section and fuel supply of the intake throat are changed to meet the needs of mixed gas at different speeds and loads.

Idle speed adjusting screw is installed on one side of carburetor to adjust idle speed. Idle stop screw is used to prevent the throttle from rotating and adjust the minimum opening of the throttle. There is a return spring above the throttle to keep the throttle closed when the throttle handle is not turned.

On some two-stroke motorcycle engines, a one-way reed valve is installed between the carburetor and the cylinder block to prevent the mixture from flowing back, which improves the power and economy of the engine at low speed.
