Disconnect the main throttle sensor connector and connect the setting adapter [A] between these connectors.
Special Tool - Throttle Sensor Setting Adapter: 57001 -1538
Main Throttle Sensor Output Voltage Connections to Adapter: Digital Meter (+) → R (sensor V/W) lead
Digital Meter (–) → BK (sensor BR/BK) lead
Install the following parts temporarily.
Throttle Body Assy (see Throttle Body Assy Installation in the Fuel System (DFI) chapter) Air Cleaner Housing (see Air Cleaner Housing Installation in the Fuel System (DFI) chapter) Fuel Tank (see Fuel Tank Installation in the Fuel System (DFI) chapter)
Throttle Sensor Setting Adapter [A]
Idle Speed Standard: 1 100 ±50 r/min (rpm)
Output Voltage
Standard: DC 0.64 0.68 V at idle
throttle opening
DC 3.89 4.09 V at full throttle
opening (for
reference)
NOTE
Example: In the case of a input voltage of 4.75 V.
0.64 × 4.75 ÷ 5.00 = 0.61 V
0.68 × 4.75 ÷ 5.00 = 0.65 V
Thus, the valid range is 0.61
0.65 V
If the reading is out of the standard, replace the throttle body assy.
If the reading is within the standard, remove the ECU and check the wiring for continuity between harness connectors.
Special Tool - Hand Tester: 57001-1394
Disconnect the ECU and sensor connectors.
Wiring Continuity Inspection ECU Connector [A] ←→ Main Throttle Sensor Connector [B] V/W lead (ECU terminal 25) [C] BR/BK lead (ECU terminal 13) [D]
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).

Coolant Level Inspection
NOTE
Check the level when the engine is cold (room or ambient
temperature).
Check the coolant level in the reserve tank [A] with the
motorcycle held perpendicular (Do not use the sidestand).
If the coolant level is lower than the “L” level line [B], remove
the upper fairing assembly (s ...
Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection
NOTE
Be sure the battery is fully charged.
Turn the ignition switch to OFF.
Remove the front seat (see Front Seat Removal in the
Frame chapter).
Remove the screws [A] and the exhaust butterfly valve
actuator temporarily with the cables installed.
Disconnect the exhaust butterf ...
Camshaft Chain Tensioner Removal
NOTICE
This is a non-return type camshaft chain tensioner.
The push rod does not return to its original position
once it moves out to take up camshaft chain slack.
Observe all the rules listed below.
When removing the tensioner, do not take out the
mounting bolts only halfway. Retighteni ...
