Working principle

Motorcycle carburetor is divided into plunger carburetor and vacuum film carburetor. But no matter what kind of carburetor, they are passive fuel supply system. It can only work normally when the engine is running.

How to choose the right carburetor you need:
Because of the different manufacturers, the carburetor model may be different, and secondly, because of the different engine technology, the matched carburetor will also be different.
The main difference between them lies in the plunger port, the size of the main measuring hole, the thickness of the main oil needle, etc. If the engine displacement is large, the diameter of the plunger port will be larger, and the corresponding main measuring hole will be larger. Only in this way can the fuel reach an optimal mixing ratio, so when choosing a carburetor, the model and displacement must be matched, otherwise there will be phenomena such as insufficient fuel supply and insufficient combustion.
