multi-function display. Changing
settings while riding can distract the
operator and increase the risk of an
accident.The multi-function display is equipped
with the following:
a digital clock
a digital speedometer (which
shows riding speed)
an odometer (which shows the to-
tal distance traveled)
a tripmeter (which shows the dis-
tance traveled since it was last set
to zero)
a fuel reserve tripmeter (which
shows the distance traveled on
the fuel reserve)
an oil change indicator (which
shows when the engine oil should
be changed)
a fuel gauge

Engine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU45583
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle. NOTICE: After 1000 km (600
mi) of operation, be sure to change
the engine oil and final transmission
oil, and to clean the oil strainer.
[ECA16502]1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.NOTICE
ECA10271
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

ParkingWhen parking, stop the engine, and
then remove the key from the main
switch.
WARNING
EWA10312
Since the engine and exhaust
system can become very hot,
park in a place where pedestri-
ans or children are not likely to
touch them and be burned.
Do not park on a slope or on soft
ground, otherwise the vehicle
may overturn, increasing the
risk of a fuel leak and fire.
Do not park near grass or other
flammable materials which
might catch fire.

Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic main-
tenance and lubrication chart. In addi-
tion, the condition of the spark plug
can reveal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-6.)
2. Remove the battery. NOTICE:
When removing the battery, be
sure the key is turned to “ ”,
then disconnect the negative
lead before disconnecting the
positive lead.
[ECA17712]
3. Remove the partition between the
battery and the spark plug by re-
moving the screws.4. Remove the spark plug cap.
5. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the vehi-
cle is ridden normally).
TIPIf the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to
diagnose such problems yourself. In-
stead, have a Yamaha dealer check
the vehicle.

6 2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.2. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
TIPIf a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4…
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.4. Install the spark plug cap.
5. Place the partition in the original
position and install the screws.
6. Install the battery. NOTICE: When
installing the battery, be sure
the key is turned to “ ”, then
connect the positive lead before
connecting the negative lead.
[ECA17722]
7. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals
and that the breather hose is
properly routed, in good condi-
tion, and not obstructed. NOTICE:
If the breather hose is posi-
tioned in such a way that the
frame is exposed to electrolyte
or gas expelled from the bat-
tery, the frame could suffer
structural and external damag-
es.
