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

There are many reasons affecting high idle speed, which may be that the ambient temperature is too low, the throttle opening is too large, and the intake valve is improperly closed. After this happens, you must go to a professional maintenance agency for inspection and maintenance. Throttle is called the throat of the engine, and the function of throttle is to adjust the air intake of the engine.

The throttle is on the intake pipe of the engine. When the throttle opening becomes larger, the air entering the engine will increase. At this time, the fuel supply system can also increase fuel injection, thus increasing the engine speed. When the throttle opening decreases, the amount of air entering the engine may also decrease, thus reducing the engine speed. If there is something wrong with the throttle, it will affect the abnormal idle speed of the engine. ?

Danger of low idle speed:

1. Because the idle speed is too low, the oil-gas mixture ratio is not ideal, and it is difficult to start the cold car, it is usually necessary to drag the throttle to enrich the mixture, and the warm-up time is correspondingly long;

2. It is easy to stall when slowing down or parking, which is especially inconvenient for novices;

3. If the idle speed is too low, the gears of the engine will be difficult to match when shifting gears, and the ride comfort will not be guaranteed, which will easily lead to collision between gears and great wear;

4. More importantly, when accelerating, the power is insufficient, and the performance of the motorcycle cannot be played normally;

5. The biggest hazard of low idle speed is that the oil pump cannot work normally, which may lead to insufficient lubrication of internal parts of the engine, premature and excessive wear of parts.
