How to identify motorcycle EFI: 1. Fuel supply detection method: EFI generally supplies fuel actively, open the fuel tank cover, open the key door, and listen to the opening of the fuel tank. If there is a sound of oil suction, it is EFI; 2. How to check the throttle nozzle: Check the connection between the engine block and the air filter. There is no melted oil, only the throttle body, which is the EFI; 3. Start-up detection method: The EFI vehicle has a self-test function when it is started. When the key door is opened, the tachometer and stopwatch will respond, the pointers will move, and the LCD will change values. When performing a self-inspection on an EFI motorcycle, you can listen to see if there are any electrical sounds and whether the pump oil is spraying out. If there are engine self-check and oil pump sounds, you can basically conclude that it is an EFI motorcycle.
