How do motorcycles identify EFI?

Identification method of motorcycle EFI: 1. Detection method of oil supply: EFI generally takes the initiative to supply oil, open the fuel tank cover, open the key door and listen to the opening of the fuel tank. If there is oil absorption sound, it is EFI; 2. Inspection method of throttle nozzle: Check the connection between engine cylinder block and air filter. There is nothing like melting oil, only the throttle body, that is, EFI; 3. Start-up detection method: EFI vehicle has self-check function when starting up. When the key door is opened, the tachometer and the code meter will react, the pointer will move, and the liquid crystal will change the value. When the EFI motorcycle is self-checking, you can listen to the sound of electrical appliances and see if the pump oil is sprayed out. If there is the sound of engine self-inspection and oil pump, it can basically be concluded that it is an EFI motorcycle.
