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.

Compression Damping Force Adjustment
There are two adjustments you can make to the compression
damping force.
High Speed Compression Damping Adjuster [A]
Low Speed Compression Damping Adjuster [B]
To adjust the high speed compression damping force, turn
the outside damping adjuster with a wrench to the desired
position ...
Technical Information-Power Mode
The rider can choose from three engine power modes to suit their preferences
and road conditions.
The FI ECU controls the engine power by adjusting fuel injection, air intake,
and ignition timing. It
enables three-mode selection: Full Power (Mode F), Middle Power (Mode M), and
Low Power (M ...
