4I side stand button

6I clutch button

7I battery voltage for congruence verification

8I power from ride-by-wire relay (etv)

9I oxygen sensor for horizontal cylinder

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

19I oil pressure switch (has no effect on any engine control strategy, but information is sent to dashboard via can line)

Starter motor
Power: 0.7 Kw/12 v Direction of rotation: counter clockwise viewed from power take-off side. The starter motor is highly compact and reliable and therefore rarely gives any type of problem. In case of troubles, ensure that the starter motor cable terminal is properly tightened under the n ...

Refitting the alternator-side crankcase cover
Before the assembly make sure that the water pump unit is fitted on the generator cover (sect. 9 - 3.3, Refitting the water pump). If bearing (27) has been removed, lubricate its seat with specified grease to fit it on the generator cover (13). Fit bearing completely in its seat and orien ...
