2I start button
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)
1U vertical and horizontal cylinder fuel injector
2U vertical and horizontal cylinder coil
3U electric ride-by-wire
4U injection relay (powers fuel pump, injectors and coils)
5U starter motor relay command

7U ride-by-wire relay command
8U oxygen sensor heater for vertical and horizontal cylinder
1C connection with can network
Specific operating strategies
Idle speed
No electric motor is used for idle speed regulation (bypass is modulated
instead with the throttle valve), as idle speed
control is effected by the ride-by-wire system. Idle speed is ma ...

Battery voltage indicator (battery)
This function describes the battery voltage indicator.
To access the function it is necessary to view the ""setting" menu", using
buttons (1) "s" or (2) "t" select the "battery"
function and press the reset button (3) to confirm.
The information will be displayed as follows:

Checking the camshafts and supports
Check the cam contact surfaces for scratches, grooves, steps and waving.
Worn cams are frequently the cause of poor timing, which leads to loss of engine
power.
Place the camshaft between two centres and check the run-out on the areas
indicated using two dial gauges.
Service limit: 0.1 ...
Reassembly of belly fairing
Position the oil cooler shield (7) inserting the tab (a) into the slit (b) in
the electrical components support (s).
Note
On refitting, make sure that the tab (c) remains positioned under the
retainers (d) of the shield (7).
Fit clips (11) on bracket (13) and orient them as shown in the f ...
