adjusted to suit the prevailing conditions.
• Manifold Absolute Pressure (MAP) sensor - situated behind the airbox plenum,
top right hand side, and is connected to each of the three throttle bodies by
equal length tubes. The MAP sensor provides information to the engine ECM
which is used at shallow throttle angles (very small throttle openings) to provide
accurate engine load indications to the ECM. This degree of engine load accuracy
allows the ECM to make very small adjustments to fuel and ignition which would
otherwise not be possible from throttle angle data alone.
• Clutch switch - situated on the clutch lever. The clutch must be pulled in for the
starter motor to operate.
• Crankshaft position sensor - situated in the alternator cover. The crankshaft
position sensor detects movement of teeth attached to the alternator rotor. The
teeth give a reference point from which the actual crankshaft position is
calculated. The crankshaft position sensor information is used by the engine ECM
to determine engine speed and crankshaft position in relation to the point where
fuel is injected and ignition of the fuel occurs.
• Engine coolant temperature sensor - situated at the front of the cylinder head
in the thermostat housing. Coolant temperature information, received by the
engine ECM, is used to optimise fueling at all engine temperatures and to
calculate hot and cold start fueling requirements.
• Oxygen sensors - situated in the front end of the catalytic converter assembly.
The oxygen sensors constantly feed information to the engine ECM on the
content of the exhaust gases. Based on this information, adjustments to air/fuel
ratio are made.
• Side stand switch - situated at the top of the side stand leg. If the side stand is in
the down position, the engine will not run unless the transmission is in neutral.
• Twist grip position sensor - situated in the twist grip housing. The twist grip
position sensor is used to relay twist grip position information to the engine ECM.
The engine ECM uses this information to drive the throttle actuation motor to the
correct position.
