The most common and practical modification method is to modify the engine, which can not only improve the power of the motorcycle, but also increase the fun and safety of riding. Next, let's discuss in detail the relevant knowledge and skills of motorcycle engine modification. 1. Why do we need to modify the engine? The engine of a motorcycle is its soul and one of the cores of its performance. A good engine can give the motorcycle faster acceleration, higher speed and better control, thus giving cyclists a better experience and a safer driving environment.Therefore, modifying the engine is one of the important ways to improve the performance of motorcycles. Two. How to modify the engine? There are many ways to modify the engine, the most common of which is to replace the high-performance test engine or make some upgrades to the original engine. Next, let's take a look at several commonly used changes. ( 1) Replace the high-performance test engine. The test engine is often regarded as a powerful engine, especially in the range of 2000~3000 rpm. Replacing the test engine can significantly improve the performance of the motorcycle, but it may also increase part of the cost. ( 2) Replacing the cylinder block is another way to modify the engine. Usually, the original 40 or 50 cylinder is replaced with 75 or 85 cylinders, which can greatly improve the power of the motorcycle.But at the same time, the host and other related parts need to be replaced, which is more expensive than replacing the test engine. ( 3) Changing the gas distribution mechanism can also make the control of the motorcycle more flexible and accelerate faster, but some changes need to be made to the gas distribution mechanism, such as replacing the intake and exhaust ducts. ( 4) The function of the turbocharger is to improve the power output of the engine by increasing the intake pressure. By replacing or installing a turbocharger, the power and speed of the motorcycle can be improved, but in comparison, this method is more expensive. ( 5) Upgrade the regulator. On modern motorcycles, only by installing a high-performance regulator can the power be maximized, accelerate faster and faster. At the same time, the regulator can also make the engine emissions more environmentally friendly and economical.3. Note: Although modifying the engine improves the performance of the motorcycle, it also has some risks. Therefore, before modifying the engine, you must pay attention to the following matters. ( 1) Find a reliable modification manufacturer or technician, and don't try DIY easily. ( 2) Choose the modification method that suits you according to your actual situation. ( 3) Pay attention to safety. When riding a motorcycle after modification, you must pay attention to safety when driving. At the same time, remember not to overload the engine to avoid accidental damage to the engine. Four. In summary, modifying the engine can improve the performance of the motorcycle and give the driver a more pleasant driving experience. However, this requires us to have certain professional knowledge and awareness in order to better achieve the purpose of modifying the engine and pay attention to safety. Therefore, when modifying, you mustChoose a good modification manufacturer, choose the modification method that suits you, and remember to drive safely to ensure the safety of yourself and others.
