switch the coolant temperature display to the air intake temperature display.
When the coolant temperature display is selected, “C” is displayed before the coolant temperature.
Air intake temperature display
The air intake temperature display indicates the temperature of the air drawn into the air filter case. Push
the “RESET” button to switch the coolant temperature display to the air intake temperature display.

Even if the air intake temperature is set to be displayed, the coolant temperature warning light comes
on when the engine overheats.

When the key is turned to “ON”, the coolant temperature is automatically displayed, even if the air
intake temperature was displayed prior to turning the key to “OFF”.

NOTE: Self-diagnosis devices
The model is equipped with a self-diagnosis device for various electrical circuits. If any of those circuits
are defective, the engine trouble warning light will come on, and then the right display will indicate a
two-digit error code (e.g.,11,12,13).
Display brightness and shift timing indicator light control mode
This mode cycles through five control functions, allowing you to make the following settings in the order
listed below.

Display brightness:
This function allows you to adjust the brightness of the displays and tachometer to suit the outside
lighting conditions.

Shift timing indicator light activity:
This function allows you to choose whether or not the indicator light should be activated and whether
it should flash or stay on when activated.

Shift timing indicator light activation:
This function allows you to select the engine speed at which the indicator light will be activated.

Shift timing indicator light deactivation:
This function allows you to select the engine speed at which the indicator light will be deactivated.

Shift timing indicator light brightness:
This function allows you to adjust the brightness of the indicator light to suit your preference.

To make any settings in this mode, you have to cycle through all of its functions. However, if the key is
turned to “OFF” or the engine is started before completing the procedure, only the settings made be-
fore the “SELECT” button was last pushed will be applied.

In this mode, the right display shows the current setting for each function (except the shift timing indi-
cator light activity function).
To adjust the brightness of the multifunction meter displays and tachometer
1. Turn the key to “OFF”.
2. Push and hold the “SELECT” button.
3. Turn the key to “ON”, and then release the “SELECT” button after five seconds.
4. Push the “RESET” button to select the desired brightness level.
5. Push the “SELECT” button to confirm the selected brightness level. The control mode changes to
the shift timing indicator light activity function.
To set the shift timing indicator light activity function
1. Push the “RESET” button to select one of the following indicator light activity settings:

The indicator light will stay on when activated. (This setting is selected when the indicator light stays
on.)

The indicator light will flash when activated. (This setting is selected when the indicator light flashes
four times per second.)

The indicator light is deactivated; in other words, it will not come on or flash. (This setting is selected
when the indicator light flashes once every two seconds.)
2. Push the ”SELECT” button to confirm the selected indicator light activity. The control mode changes
to the shift timing indicator light activation function.

IMPORTANT INFORMATION
PREPARATION FOR REMOVAL AND
DISASSEMBLY
1. Before removal and disassembly, eliminate
all dirt, mud, dust and foreign material.
2. Use only the proper tools and cleaning
equipment.
Refer to the “SPECIAL TOOLS”.
3. When disassembling, always keep mated
parts together. This includes gears, cylin-
ders, pistons and other parts that have been
“mated” through normal wear. Mated parts
must always be reused or replaced as an as-
sembly.
4. During disassembly, clean all of the parts
and place them in trays in the order of disas-
sembly. This will speed up assembly and al-
low for the correct installation of all parts.
5. Keep all parts away from any source of fire.
EAS00021
REPLACEMENT PARTS
Use only genuine Yamaha parts for all replace-
ments. Use oil and grease recommended by
Yamaha for all lubrication jobs. Other brands
may be similar in function and appearance, but
inferior in quality.
EAS00022
GASKETS, OIL SEALS AND O-RINGS
1. When overhauling the engine, replace all
gaskets, seals and O-rings. All gasket sur-
faces, oil seal lips and O-rings must be
cleaned.
2. During reassembly, properly oil all mating
parts and bearings and lubricate the oil seal
lips with grease.

LOCK WASHERS / PLATES AND COTTER
PINS
After removal, replace all lock washers / plates
1 and cotter pins. After the bolt or nut has been
tightened to specification, bend the lock tabs
along a flat of the bolt or nut.
EAS00024
BEARINGS AND OIL SEALS
Install bearings and oil seals so that the
manufacturer’s marks or numbers are visible.
When installing oil seals, lubricate the oil seal
lips with a light coat of lithium-soap-based
grease. Oil bearings liberally when installing, if
appropriate.
1Oil seal
Do not spin the bearing with compressed air
because this will damage the bearing sur-
faces.

CIRCLIPS
Before reassembly, check all circlips carefully
and replace damaged or distorted circlips. Al-
ways replace piston pin clips after one use.
When installing a circlip
1, make sure the
sharp-edged corner
2 is positioned opposite
the thrust
3 that the circlip receives.
