Tachometer unit
The electric tachometer allows the rider
to monitor the engine speed and keep it
within the ideal power range.
When the key is turned to “ON”, the ta-
chometer needle will sweep once
across the r/min range and then return
to zero r/min in order to test the electri-
cal circuit.
CAUTION:
ECA10031
Do not operate the engine in the ta-
chometer red zone.
Red zone: 8000 r/min and above
This tachometer unit is equipped with a
clock.
To set the clock:
1. Push both the “SELECT” and “RE-
SET” buttons for at least two sec-
onds.
2. When the hour digits start flashing,
push the “RESET” button to set the
hours.
3. Push the “SELECT” button to
change the minutes.
4. When the minute digits start flash-
ing, push the “RESET” button to
set the minutes.
5. Push the “SELECT” button to start
the clock.
NOTE:
After setting the clock, be sure to
push the “SELECT” button before
turning the key to “OFF”, otherwise
the clock will not be set.
When the key is turned to “OFF”,
the clock display will remain on for
48 hours and then go off to prevent
the battery from discharging.
EAU12181
Coolant temperature gauge
With the key in the “ON” position, the
coolant temperature gauge indicates
the temperature of the coolant. When
the key is turned to “ON”, the coolant
temperature gauge needle will sweep
once across the temperature range and
then return to “C” in order to test the
electrical circuit. The coolant tempera-
ture varies with changes in the weather
and engine load. If the needle reaches
or enters the red zone, stop the vehicle
and let the engine cool. (See
page 6-35.)

Checking the wheel bearings
The front and rear wheel bearings must
be checked at the intervals specified in
the periodic maintenance and lubrica-
tion chart. If there is play in the wheel
hub or if the wheel does not turn
smoothly, have a Yamaha dealer check
the wheel bearings.

Battery
This model is equipped with a
sealed-type (MF) battery, which does
not require any maintenance. There is
no need to check the electrolyte or to
add distilled water.
CAUTION:
ECA10620
Never attempt to remove the battery
cell seals, as this would permanent-
ly damage the battery.
WARNING
EWA10760
Electrolyte is poisonous anddangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15
minutes and seek prompt
medical attention.
Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.
KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
