2. Remove the spark plug caps.
3. Use the spark plug wrench in the
tool kit to remove the spark plugs
as shown.Inspection
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
the condition of the engine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.

place. Warm up the engine at idle
for 15 minutes.NOTE:@ Be sure the motorcycle is positioned
straight up when checking the oil level.

false readings. @
2. The oil tank is located behind the
engine cylinders. With the engine
stopped, check the oil level
through the level window located
on the right side of the oil tank.
3. The oil level should be between
the maximum and minimum
marks. If the level is low, fill engine
with sufficient oil to raise it to the
specified level.Engine oil and oil filter element re-

WARNING
@ This motorcycle is fitted with super
high-speed running tires. The fol-
lowing points must be observed in
order for you to make fully effective
use of these tires.l
Never fail to use the specified
tires in tire replacement. Other
tires may have a danger of
bursting at super high-speeds.
l
New tires have a relatively low
grip on the road surface until
they have been slightly worn.
Therefore, approximately 100 km
should be traveled at normal
speed before any high-speed
riding is done.
l
Before any high-speed runs, the
tires should be warmed-up suf-
ficiently.
l
Always inflate to the correct tire
pressure according to the oper-
ating conditions.

Fuse replacementThe fuse boxes are located under the
rider seat and the main fuse case is at-
tached to the starter relay.
If any fuse is blown, turn off the main
switch and the switch of the circuit in
question. Install a new fuse of specified
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again, con-
sult a Yamaha dealer.
EC000103
CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @
