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 Erasing
When repair has been done, warning indicator light (LED) and warning symbol go off and service code are not displayed. But the service codes stored in memory of the ECU are not erased to preserve ...

Starter Clutch Assembly
Install the one-way clutch [A] to the driven gear. Face the circlip side of the one-way clutch to inside. Install the new snap ring [B] to the one-way clutch. Install the drive gear [C] while turn it counterclockwise [D]. Apply molybdenum disulfide oil solution to the needle bearing ...

Battery Ground
Before completing any service on the motorcycle, disconnect the battery cables from the battery to prevent the engine from accidentally turning over. Disconnect the ground cable (–) first and then the positive (+). When completed with the service, first connect the positive (+) cable to the p ...

Bolts, Nuts and Fasteners Tightness Inspection
Check the tightness of the bolts and nuts listed here. Also, check to see that each cotter pin is in place and in good condition. NOTE For the engine fasteners, check the tightness of them when the engine is cold (at room temperature). If there are loose fasteners, retighten them to ...
