Note:
(1): D-J Method: When the engine load is light like at idling or low speed, the ECU determines the injection quantity by calculating from the throttle vacuum (vacuum sensor output voltage) and engine speed (crankshaft sensor output voltage). This method is called D-J method.
(2): α-N Method: As the engine speed increases, and the engine load turns middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening (throttle sensor output voltage) and the engine speed. This method is called α-N method.
*: This depends on the number of stopped cylinders.
The main throttle sensor is a rotating variable resistor that change output voltage according to throttle operating. The ECU senses this voltage change and determines fuel injection quantity, and ignition timing according to engine rpm, and throttle opening.

Service Code ErasingStick Coil Installation
Apply a thin coat of grease [A] to the stick coils for easy
installation.
Insert the stick coils so that the coil heads align with the
lines [B] on the cylinder head cover.
NOTICE
Do not tap the coil head while installing the coil.
After installation, be sure the stick coils are ...
Water Temperature Sensor Removal/Installation
NOTICE
Never drop the water temperature sensor especially
on a hard surface. Such a shock to the sensor can
damage it.
Remove the throttle body assy (see Throttle Body Assy
Removal in the Fuel System (DFI) chapter).
Drain the coolant (see Coolant Change in the Periodic
Maintenance c ...
Mode-switching
Depress the S-KTRC button on the left handlebar switch
to change the mode. The mode can be changed only when
the throttle grip is closed completely.
The S-KTRC OFF can be selected only when the motorcycle
is at a stop. Changing to mode 1 from S-KTRC OFF
is possible while riding.
