Introduction
When the rider presses the start button, with all the safety conditions required to enable engine start met, the engine control unit enables the relay that activates the starter motor.
Component assembling position
Connection on starter motor relay.
Connection wiring diagram
Mt starter motor, ccm engine control connection. 4 Starter motor relay activation, blue/black - b/bk, a key on power (+15 from hands free relay 30), r battery power (+30), 3 red/black - r/bk, m black - bk, b black - bk.
In the event of fault
In the event of a starter motor relay fault, the engine will not start.
Fault codes generated and possible correlated faults
The engine control unit generates no fault code in the event of a starter motor relay fault.
No errors are indicated on the dashboard.
Possible correlated faults: the starter motor cannot be operated. Check:
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
If none of the tests described above identifies the problem and the power supply and ground for the engine control unit are in correct working order, replace the engine control unit.
Component replacement methods
No special measures are necessary in order to replace the starter motor relay.
Refitting the front brake master cylinder
Insert the front brake master cylinder unit (1) on the right side of the
handlebar to bring the terminal internal edge in
correspondence to the bolted joints (a).
Fit the terminal (12) on the handlebar inserting the screws (15).
Tighten the terminal (12) retaining screws to a torque of 10 ...
Chain lubrication
The chain fitted on your motorcycle has o-rings that keep dirt
out of and lubricant inside the sliding parts.
So as not to damage these seals when cleaning the chain,
use special solvents and avoid aggressive washing with highpressure
steam cleaners.
After cleaning, blow the chain dry with ...
Removal of the cylinder/piston assembly
Loosen the clamps (7) and remove the hoses (8) and (9) from the cylinder
barrels (10) and from the alternator-side
crankcase cover.
If damaged, unscrew the unions (6).
Note
The following procedure is described with the engine removed from the
frame and the cylinder head r ...
