10I oxygen sensor for vertical cylinder

11I map sensor for horizontal cylinder

12I map sensor for vertical cylinder

13I main throttle grip position sensor

14I secondary throttle grip position sensor

15I main throttle valve position sensor

16I secondary throttle valve position sensor

17I engine temperature sensor

18I air temperature sensor
