Which is better for a motorcycle carburetor, the original one or a new one?
Release date:2025.05.09

It's a bit inappropriate to discuss carburetors during the fourth national standard era. After all, for motorcycles, it's already a distant past, and our bright future should be pinned on electronic fuel injection systems. However, there are still a large number of carburetor motorcycles on the market, so discussing motorcycle carburetors is also of practical significance.


The carburetor is a fuel supply device for motorcycles, mainly serving to atomize fuel. This device is a simple mechanical structure, mainly composed of three major parts: the shell, the plunger, and the float chamber. Of course, if further classified, there are many delicate small parts, such as the main measurement hole, idle measurement hole, fuel float, float needle, and main fuel needle, etc. However, under normal usage conditions, The possibility of these parts being damaged is not high, so theoretically, the carburetor of the original vehicle could accompany the motorcycle to its end of life.


However, during use, due to human factors or the quality of the fuel and other reasons, the carburetor may also have poor working conditions, which can lead to some faults in the motorcycle, such as difficult starting, weak acceleration, increased fuel consumption, etc. At this time, some motorcycle owners may consider replacing the carburetor.


However, the fact is that the atomization performance of the cheap carburetors sold on the market is far less than one-third of that of the original carburetors on the vehicle. The reason is simple: as a major fuel supply system for motorcycles, the carburetors installed on the original vehicle are relatively more precise, and some brand models also adopt more advanced brands, such as Sangoku or Jingbin. Under such circumstances, if the carburetor of the original vehicle is replaced at will, it will only make the vehicle's combustion condition worse and worse. Therefore, the rider shares that it is not recommended to replace the carburetor of the original vehicle at will.


So what should be done when the carburetor of the original vehicle malfunctions? At this point, we only need to thoroughly clean and readjust the carburetor, and its performance will return to normal. However, this is a technical job, and users may not have the ability to do so. Therefore, it is necessary to seek professional technicians to repair the carburetor, and its performance will definitely meet the current combustion requirements of the powertrain.


To sum up, under no circumstances should the carburetor of the original car be replaced at will. Although the newly replaced carburetor may seem to work well at first glance, after being used for a period of time, it will be found that its performance may not reach that of the original one at all. Therefore, the carburetor of the original car should be repaired or cleaned if possible and should not be replaced easily.
