Periodic Maintenance Procedures
Repeat the same procedure for other bypass screws.
Repeat the synchronization.
If the vacuums are correct, check the output voltage of
the main throttle sensor (see Main Throttle Sensor Output
Voltage Inspection in the Fuel System (DFI) chapter).
Main Throttle Sensor Output Voltage
Connections to ECU
Meter (+) → Y/W lead (terminal 7)
Meter (–) → BR/BK lead (terminal 28)
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.
Coolant Level Inspection
Check the level when the engine is cold (room or ambi-
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].
For refilling, add the specified mixture of coolant
and soft water.
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.
Adding water alone dilutes the
