Digital speedometer
This speedometer is equipped with:
l
an odometer
l
two trip odometers
l
a fuel reserve trip meter
l
a clock
NOTE:

For UK models only:
To change the speedometer display
from kilometers to miles, press the “SE-
LECT” button for at least two seconds.
Odometer and trip meter modes
Use the trip meters to estimate how far
you can ride on a tank of fuel.
Use the fuel reserve trip meter to see
the distance traveled from when the
fuel level dropped to the reserve level.
Selecting a mode
Push the “SELECT” button to change
between the odometer mode “ODO”
and the trip odometer modes “TRIP 1”
and “TRIP 2” in the following order:
“ODO”
®
“TRIP 1”
®
“TRIP 2”
®
“ODO”
If the fuel level indicator light comes on
the odometer display will automatically
change to the fuel reserve trip meter
mode “TRIP F” and start counting the
distance traveled from that point. Push
the “SELECT” button to change be-
tween the fuel odometer, trip odometer
and odometer modes in the following
order:
“TRIP F”
®
“TRIP 1”
®
“TRIP 2”
®
“ODO”
®
“TRIP F”Resetting a meter
To reset a trip odometer to 0.0, select it
by pushing the “SELECT” button and
push the “RESET” button for at least
one second.
To reset the fuel reserve trip meter, se-
lect it by pushing the “SELECT” button
and push the “RESET” button for at
least one second. The display will re-
turn to “TRIP 1”. If you do not reset the
fuel reserve trip meter manually, it will
automatically reset and return to “TRIP
1” after refueling and the motorcycle
has traveled 5 km (3.1 miles).
NOTE:

After the fuel reserve trip meter is reset,
the display always returns to the “TRIP
1” mode. If “TRIP 2” was being used
before the fuel reserve trip meter is re-
set, be sure to push the “SELECT” but-
ton to change back to the “TRIP 2”
mode.

5. Engine overheatingEW000070
WARNING
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be blown out
under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the engine has
cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over the radiator cap
and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape.
When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the recom-
mended coolant as soon as possible.
Wait until the
engine has cooled.Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.
Level is low, check the
cooling system for leakage.
No
leakage.
Leakage.Ask a Yamaha dealer to inspect
and repair the cooling system.
Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.

c. Round off the original valve pad num-
ber according to the following table.
EXAMPLE:
Original valve pad number = 148 (thickness
= 1.48 mm)
Rounded value = 150
d. Locate the rounded number of the
original valve pad and the measured
valve clearance in the valve pad
selection table. The point where the
column and row intersect is the new
valve pad number.
NOTE:
The new valve pad number is only an
approximation. The valve clearance
must be measured again and the above
steps should be repeated if the measure-
ment is still incorrect.
e. Install the new valve pad 1 and the
valve lifter 2.
NOTE:
• Lubricate the valve pad with molybde-
num disulfide grease.
• Lubricate the valve lifter with molyb-
denum disulfide oil.
• The valve lifter must turn smoothly
when rotated by hand.
• Install the valve lifter and the valve pad
in the correct place.
f. Install the exhaust and intake cam-
shafts, timing chain and camshaft
caps.
NOTE:
• Refer to “CAMSHAFTS” in chapter 4.
• Lubricate the camshaft lobes and cam-
shaft journals.
• First, install the exhaust camshaft.
• Align the camshaft marks with the
camshaft cap marks.

NOTE:
When draining the coolant from the
coolant reservoir, be sure to tilt the res-
ervoir so that coolant cannot flow

WARNINGWARNING
A hot radiator is under pressure. There-
fore, do not remove the radiator cap
when the engine is hot. Scalding hot
fluid and steam may be blown out,
which could cause serious injury. When
the engine has cooled, open the radiator
cap as follows:
Place a thick rag or a towel over the
radiator cap and slowly turn the radia-
tor cap counterclockwise toward the
detent to allow any residual pressure to
escape. When the hissing sound has
stopped, turn the radiator cap counter-
clockwise while pressing down on it
and then remove it.
