What is the reason why an EFI motorcycle tends to stall after deceleration?

This may be due to issues with the sensors or the intake system. If this occurs, it is recommended to inspect both the sensors and the engine's intake system. If the sensors are faulty, they should be replaced immediately. If there is a problem with the engine's intake system, repairs are necessary. More details are as follows: 1. Purpose of ECU: Motorcycles with EFI engines are equipped with an ECU, which serves the same function as in cars—controlling the engine's operation. The ECU is often referred to as the brain of the engine; without it, the engine cannot function properly. 2. Reasons for ECU malfunction: The ECU collects information from various sensors, processes it, and then controls the engine's operation through actuators. If a sensor is damaged, the ECU cannot gather crucial data, which affects the engine's normal operation. Similarly, if an actuator is damaged, the ECU cannot control the engine, leading to operational issues. Therefore, damaged sensors should be repaired immediately.
