What is the reason for the high idle speed of motorcycles?

There are many reasons for high idle speed, which may be that the ambient temperature is too low, the throttle opening is too large, or the intake valve is not tight. After this happens, you must go to a professional maintenance agency for inspection and maintenance. Throttle is called the throat of the engine, which is used to control the intake of the engine. The throttle valve is located on the intake pipe of the engine. When the throttle opening becomes larger, the air entering the engine will increase, and the fuel supply system will also increase the fuel injection, thus increasing the engine speed. When the throttle opening decreases, the amount of air entering the engine will also decrease, so the engine speed will also decrease. If the throttle valve fails, it will lead to abnormal engine idle speed. If the throttle is broken, just replace it with a brand new one. If the idle speed of the automaton is too high after the cold start of the engine, it is normal, because the temperature is relatively low in winter and the mixture is relatively thick when the engine is just started. Too rich mixture will make the engine start better and warm up the engine quickly. The lower the engine temperature, the better. The engine has a normal operating temperature range. Increasing idle speed can make the engine warm up quickly. Only when the temperature of the engine is within the normal working temperature range can the engine have the highest efficiency and the strongest power.
