Front Wheel Rotation Sensor Signal Inspection
The front wheel rotation sensor sends the signal to the ECU through the KIBS hydraulic unit (KIBS equipped models). For other than KIBS equipped models, the signal is sent directly to the ECU.
The ECU uses the wheel rotation sensor signal for KTRC control.
The service code 27 is detected with the ECU.

Standard: 209 
231 Ω
If the resistance is out of the standard, replace the main harness.
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

This sensor has a weight [A] with two magnets inside,
and sends a signal to the ECU. But when the motorcycle
banks 60 
70В° or more to either
side (in fact falls down),
the weight turns and the signal changes. The ECU senses
this change, and stops the fuel pump relay, the fuel injectors
and the ignition system.
Hall IC [B] When the motorcycle is down, the ignition switch is left ON. If the starter button is pushed, the electric starter turns but the engine does not start. To start the engine again, raise the motorcycle, turn the ignition switch to OFF, and then turn it to ON.

Gear Position Switch Output Voltage InspectionTire Wear, Damage
As the tire tread wears down, the tire
becomes more susceptible to puncture
and failure. An accepted estimate is
that 90% of all tire failures occur during
the last 10% of tread life (90% worn).
So it is false economy and unsafe to
use the tires until they are bald
