How does a Yamaha carburetor work?

1.      The job of a motorcycle carburetor is to supply an air/fuel mixture to the internal combustion engine

2.      The carburetor regulates the flow of air through its main hole (venturi). This flow of air draws in fuel and the mixture enters the engine through an intake valve

3.      The Venturi principle/effect (discussed below) is critical to successful operation

4.      The motorcycle carburetor consists of a bowl, central hole, passage, nozzle, vent, slider, concentrator (also known as choke), idle regulator, air-fuel ratio regulator, and the usual accelerator pump


What are the characteristics of motorcycle carburetor?

1.      Yamaha carburetors are simple and easy to DIY repair

2.      Usually no computer/software is required to tweak it, making it valuable in racing applications

3.      No pressurized fuel line is required for operation

4.      Less efficient than fuel injection, especially when the engine is cold or decelerated

5.      You may become fussy after not using it for a long time

6.      Multiple carburetor Settings on a vehicle with multiple cylinders need to be properly synchronized with each other to work properly


What is the type of motorcycle carburetor?

1.      Carburetors come in two categories: mechanical sliding or constant velocity (CV). In a mechanical sliding carburetor, the rider's throttle input directly raises or lowers the carburetor slide to regulate how much air flows through the holes and into the engine. Mechanical sliding carbohydrates are popular in racing, off-road and other performance applications. For best performance, the accelerator pump is usually built into a mechanically sliding carburetor to deliver the required fuel at any given time.

2.      Isokinetic carburetors provide better performance at different altitudes and a smoother throttle response across all throttle ranges. CV carbohydrates have no physical connection between the slider and the throttle mounted on the handlebars. Instead, the throttle opens a butterfly valve in the throat of the motorcycle carburetor, and the vacuum pressure lifts the slider as needed.
