What is the unstable idle speed of curved beam motorcycle? Up and down.

The reasons for the unstable idle speed of EFI motorcycles are:

1, carbon deposit in throttle body, air passage blocked;

2. The fuel pressure is too low and the intake manifold leaks;

3, sensor failure, etc. Faults in the air intake system, fuel system and ignition system of the engine will lead to rapid instability of the engine, so it is best to go to the repair shop for detailed inspection.

The idling instability of EFI motorcycles is mainly manifested in the following situations.

Idle speed is high or low, either high or direct flameout. Idle speed instability is usually accompanied by idle speed jitter. Idle instability can be said to be one of the most common faults of motorcycles. In general, the engine idle speed is determined, and the specific level depends on the adjustment of specific models. Most models are at 1400 to 1500 rpm, with high idle speed, high fuel consumption and low idle speed, which is easy to stall.
