16. CRANK POSITION SENSOR (CPS):
The CPS is located inside the Engine cover LH under
the Stator coils as shown in photo.
It provides an alternating electrical pulse to the ECU,
to determine crankshaft speed and TDC position of
the piston in compression stroke. This input will help
the ECU to optimize both fuel injection as well as
Ignition advance required to suit the crankshaft
rotation speed (RPM).
In the event throttle is wide open, leading to
crankshaft speed above 7000~7400 150 RPM, the
high frequency electrical pulses from the crank
position sensor will prompt the ECU to restrict fuel
supply so that the crank speed reduces to safe levels.
This is a safety aspect to prevent damage to moving
engine parts.

STARTER MOTOR
The Starter motor is assembled on top of the
crankcase behind the cylinder barrel.
The starter motor is activated by a solenoid, whenever
the starter button is pressed to start the engine. While
cranking, when the crank speed attains 600 RPM the
ECU commands the starter solenoid to disconnect the
power supply to the starter motor so that is will stop
spinning.
Also in case the engine does not start within 15 seconds
of depressing the starter button, the solenoid will
disconnect power supply to the starter motor and will
reset to normal condition only after the starter switch
is released and after a time delay of about 5 seconds
AND Crank is at Zero RPM.
This is a safety feature to safeguard the starter motor,
solenoid and the starter sprag clutch.
