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.

Intake Air Temperature Sensor Removal
NOTICE
Never drop the intake air temperature sensor especially
on a hard surface. Such a shock to the sensor
can damage it.
Remove the fuel tank (see Fuel Tank Removal in the Fuel
System (DFI) chapter).
Disconnect the connector [A] from the intake air temperature
sensor.
Remove the da ...
Chain Slack Inspection
Set the motorcycle up on its side
stand.
Rotate the rear wheel to find the position
where the chain is tightest, and
measure the maximum chain slack
by pulling up and pushing down the
chain midway between the engine
sprocket and rear wheel sprocket.
A. Chain Slack
