Motorcycles on the mainland market have mainly experienced four eras of two-stroke, four-stroke, carburetor and EFI. In addition to EFI motorcycles, other models and carburetors are inseparable.

The so-called carburetor, in fact, is a fuel supply system of the internal combustion engine, it is widely used in the motorcycle, the 1980s and 1990s is almost a motorcycle essential, this device has a simple structure, easy maintenance, stable performance, low cost, very suitable for the single-cylinder form of the road type motorcycle.

However, with the continuous upgrading of technology and the increasingly strict environmental protection policies, this device was eventually replaced by the electric spray system. Therefore, the motorcycles produced and sold today, whether single-cylinder or multi-cylinder, whether fun models or road motorcycles, no longer use carburetors.

Carburetor and EFI have their own advantages and disadvantages

At this point, this article should end. However, in accordance with the practice, we should still discuss the advantages and disadvantages of EFI and carburetor, after all, the atmosphere has come to this step, not to mention the deep-seated reasons for the rider to ask, the high probability is also to see some shortcomings of EFI, it will be felt.

As has been said before, the biggest advantage of carburetor motorcycles is low cost and easy maintenance, but there are also riders who reflect that the power of some carburetor motorcycles will be better than the same displacement of the electric injection model, although this is not an individual or common phenomenon, but also can find theoretical support and practical performance.

Because some models only supply enough fuel to release the due power, and the EFI system in order to achieve the best fuel effect, the precise chemical control of oil, to a certain extent, will limit the power, so some models have this performance is normal, to put it bluntly, its internal combustion engine is only suitable for carburetor this form of oil supply.

However, its shortcomings are also very obvious, high reaction is serious, start-up difficulties, high fuel consumption is basically the normal performance, especially in low temperature and high altitude areas.

The electric injection motorcycle almost solves all the shortcomings of the carburetor motorcycle, because it is a precise active fuel supply system, so it will not waste every drop of fuel, and then can achieve the purpose of fuel saving, and because of the characteristics of accurate fuel supply, so even at low temperatures or high altitudes, there will be no difficulty in starting, high reaction serious performance.

In addition, the EFI system will have more derivative space, for example, electronic throttle, cruise control, traction control, etc., are based on this, this function of the carburetor simply cannot be achieved.

However, due to the complex structure, numerous sensors and actuators, and the need for a large number of original codes as data support, the later maintenance will be very troublesome, and once there is no professional equipment and related skills, it is almost a black eye.

The most important once the system adjustment does not match, it will be easy to have unstable operation and high failure rate, and then there will be power decline, high fuel consumption, unstable idle speed, weak climbing, and so on.

Based on this, some small partners because they choose the unreliable EFI motorcycle, and then they will miss the stability and performance of the carburetor motorcycle, and think that the carburetor motorcycle is a boutique, EFI is nothing.

But in fact, motorcycle EFI technology has been very mature, as long as it is the mainstream model of the head brand, the failure rate of EFI motorcycle is not high, and the performance will be significantly better than the carburetor model. And with the improvement of maintenance personnel skills and the popularization of professional equipment, the overhaul and maintenance of EFI motorcycles are no longer so difficult.
