Main Throttle Sensor Output Voltage Connections to ECU

Meter (+) → Y/W lead (terminal 7) Meter (–) → BR/BK lead (terminal 28)

Standard:

1.055 ~ 1.095 V DC (at idle throttle opening)

If the output voltage is out of the range, check the throt- tle input voltage (see Main Throttle Sensor Input Voltage Inspection in the Fuel System (DFI) chapter).

• Remove the vacuum gauge hoses and install the vacuum

hoses and rubber caps.

Idle Speed Inspection

• Start the engine and warm it up thoroughly.

• With the engine idling, turn the handlebar to both sides

[A].

WARNING

Operation with improperly adjusted, incorrectly routed or damaged cables could result in an unsafe riding condition.

If handlebar movement changes the idle speed, the throttle cables may be improperly adjusted or incorrectly routed or damaged. Be sure to correct any of these conditions before riding (see Throttle Control System Inspection or Cable, Wire, and Hose Routing section in the Appendix chapter).

• Check idle speed.

If the idle speed is out of the specified range, adjust it.

Idle Speed

Standard: 1 300 ±50 r/min (rpm)

Idle Speed Adjustment

• Start the engine and warm it up thoroughly.

• Turn the adjusting screw [A] until the idle speed is correct.

○Open and close the throttle a few times to make sure that

the idle speed is within the specified range. Readjust if

necessary.

 

 

Fuel Hose Inspection (fuel leak, damage, installation condition)

○The fuel hose is designed to be used throughout the mo-

torcycle’s life without any maintenance. However, if the

motorcycle is not properly handled, the high pressure in- side the fuel line can cause fuel to leak [A] or the hose to burst. Remove the fuel tank (see Fuel Tank Removal in the Fuel System (DFI) chapter) and check the fuel hose. Replace the fuel hose if any fraying, cracks [B] or bulges [C] are noticed.

• Check that the hoses are routed according to Cable, Wire, and Hose Routing section in the Appendix chapter.

Replace the hose if it has been sharply bent or kinked. Hose Joints [A]

Fuel Hose [B]

 

• Check that the hose joints are securely connected.

○Push and pull [A] the hose joint [B] back and forth more

than two times, and make sure it is locked.

WARNING

Make sure the hose joint is installed correctly on the delivery pipe by sliding the joint, or the fuel could leak.

If it does not locked, reinstall the hose joint.

 

Evaporative Emission Control System (California Model)

Evaporative Emission Control System Inspection

• Inspect the canister as follows.

○Remove:

Left Center Fairing (see Center Fairing Removal in the

Frame chapter)

○Remove the canister [A], and disconnect the hoses from

the canister.

○Visually inspect the canister for cracks or other damage.

If the canister has any cracks or bad damage, replace it

with a new one.

NOTE

○The canister is designed to work well through the motor-

cycle’s life without any maintenance if it is used under

normal conditions.

 

 

• Check the liquid/vapor separator as follows.

○Remove:

Left Center Fairing (see Center Fairing Removal in the

Frame chapter)

○Disconnect the hoses from the separator, and remove the

separator [A] from the motorcycle left side.

○Visually inspect the separator for cracks and other dam-

age.

If the separator has any cracks or damage, replace it with a new one.

○To prevent the gasoline from flowing into or out of the

canister, hold the separator perpendicular to the ground.

• Check the hoses of the evaporative emission control sys- tem as follows.

○Check that the hoses are securely connected and clips

are in position.

○Replace any kinked, deteriorated or damaged hoses.

○Route the hoses according to Cable, Wire, and Hose

Routing section in the Appendix chapter.

○When installing the hoses, avoid sharp bending, kinking,

flattening or twisting, and route the hoses with a minimum

of bending so that the emission flow will not be obstructed.

 

Cooling System

Coolant Level Inspection

NOTE

○Check the level when the engine is cold (room or ambi-

ent 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], re- move the right center fairing (see Center Fairing Removal in the Frame chapter) and unscrew the reserve tank cap, and add coolant to the “F” level line [C].

“L”: low

CAUTION

For refilling, add the specified mixture of coolant and soft water. Adding water alone dilutes the coolant and degrades its anticorrosion properties. The diluted coolant can attack the aluminum en- gine parts. In an emergency, soft water alone can be added. But the diluted coolant must be returned to the correct mixture ratio within a few days. If coolant must be added often or the reservoir tank has run completely dry, there is probably leakage in the cooling system. Check the system for leaks. Coolant ruins painted surfaces. Immediately wash away any coolant that spills on the frame, engine, wheels or other painted parts.

“F”: full

 

 

Radiator Hose Damage and Installation Condition Inspection

○The high pressure inside the radiator hose and pipe can

cause coolant to leak [A] or the hose to burst if the line is

not properly maintained.

• Visually inspect the hoses for signs of deterioration. Squeeze the hoses. A hose should not be hard and

brittle, nor should it be soft or swollen.

Replace the hose if any fraying, cracks [B] or bulges [C] are noticed.

• Check that the hoses are securely connected and clamps

are tightened correctly.

Torque - Radiator Hose Clamp Screws: 2.0 N·m (0.20 kgf·m, 17 in·lb)

Air Suction System

Air Suction System Damage Inspection

• Remove the fuel tank (see Fuel Tank Removal in the Fuel System (DFI) chapter).

• Remove the fuel hose (see Fuel Hose Replacement).

• Connect:

Fuel Pump Lead Connector [A]

Extension Tube [B]
