Hello, everyone. What kind of motorcycle is this? What carburetor? Its air door is different from the general carburetor, and it needs to be inserted into the hole to tighten the screws.

This is an ordinary plunger carburetor for curved beam motorcycles, but this plunger refers to the plunger type of throttle, not the plunger type of throttle. This kind of carburetor damper is not uncommon, but it is different from other choke valves in principle, but the purpose is the same, all of which are to enrich the mixture. This carburetor is widely used, such as the common Suzuki bent beam motorcycle.

There are generally two kinds of throttle valves of motorcycle carburetor, generally the choke valve, that is, through a baffle-shaped component, the air is blocked from entering, so as to improve the concentration of mixed gas. There is another one, such as the one in the picture, which increases the concentration of mixed gas by opening the enrichment nozzle and injecting more gasoline. Although the implementation method is slightly different, the purpose and effect are the same, both of which are to improve the depth of mixed gas and improve the starting and preheating effect of cold car.
