Starting system description

The starting system transmission is between the rotor of the motor and driving shaft with free wheel coaxial to the
flywheel and torque limiter on the intermediate shaft.
The limiter is calibrated to 10 Kgm (100 N·m); the function of this component is to safeguard engine structure and
engine ignition kinematism in case of incorrect engine ignition manoevre with subsequent voltage build-up of inverse
revolution.
The free wheel allows a suitably silent starting.
Command of the starting (excitation of the solenoid starter) is slaved by consensus of the side stand and the OFF/
RUN emergency switch, thus not allowing ignition in dangerous conditions.
The engine ignition command circuit is not controlled by the immobilizer system, so before activating the engine
ignition system in an anomalous manner, check the consensus of the immobilzer.
With regard to checking the consensus circuit, see Chapter 4-ELECTRICAL EQUIPMENT in the X9 500 cc vehicle
Service Station Manual; whilst for controls of the driving shaft command transmission, take action as described in
Chapter 6-FLYWHEEL AND ENGINE IGNITION SYSTEM.
