What if the motorcycle engine can't come down at idle speed?

The idling speed of EFI car is unstable, and many motorcycle maintenance masters don't know where to start. Today, I will discuss this issue with you. If there is anything wrong, please leave a message to correct me. The other is not adjustable and is set by a computer program. If the idle speed is unstable, it must be caused by vehicle failure. As follows.

Mechanical failure: valve leakage, negative pressure pipe leakage, injector failure, resulting in poor atomization. The mixture is too thin or too rich due to the blockage or oil leakage of the injector. Too high oil pressure will lead to too rich mixture, and too low oil pressure will lead to too thin mixture. The fuel filter is blocked and the fuel pressure regulator is out of order.

At present, there are two kinds of EFI motorcycles in China, one is adjustable idle speed and the other is not adjustable. An adjusting screw with adjustable idle speed is installed on the air passage beside the throttle body, and the air intake is controlled by adjusting the idle speed screw, so as to adjust the idle speed.

Some netizens said that the idle speed of Haojue Guosi motorcycle was too high. How to adjust the idle speed Some people will ask if they can adjust the idle speed by themselves, and the answer is no. Haojue's four motorcycles are all EFI, especially the throttle limit screw under the throttle. All throttle limit screws have been adjusted and locked before leaving the factory. Do not adjust the engine idle speed by yourself. ECU controls the throttle body idle solenoid valve or idle stepper motor to adjust the engine idle speed, which is basically impossible to adjust. Even if the engine idle speed is adjusted after sale, there is no right to adjust the throttle limit screw. Only the manufacturer has the right to adjust and debug the engine idle speed.
