Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and
equipped to perform these particular
services.

Owner’s tool kitThe owner’s tool kit is located under
the seat. (See page 3-19.)
The service information included in this
manual and the tools provided in the
owner’s tool kit are intended to assist
you in the performance of preventive
maintenance and minor repairs. How-
ever, additional tools such as a torque
wrench may be necessary to perform
certain maintenance work correctly.TIPIf you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.1. ZAUM1020

6To 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.
2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.
3. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.To install the spark plug
1. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
2. 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.3. Install the spark plug cap.
4. Place the rear storage compart-
ment in the original position and
install the bolts.
5. Close the seat.

by removing the bolts.
6. Remove the oil filter element and
O-ring.7. Check the O-ring for damage and
replace it if necessary.
8. Install the new oil filter element
and an O-ring.
9. Install the oil filter element cover
by installing the bolts, then tight-

TIPMake sure that the O-ring is properly
seated.
10. Install the washer and the engine
oil drain bolt, and then tighten the
drain bolt to the specified torque.TIPMake sure that the washer is properly
seated.11. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the oil filler
cap.TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.

drain bolt and its new gasket, and
then tighten the bolt to the speci-
fied torque.
7. Refill with the specified amount of
the recommended final transmis-
sion oil. WARNING! Make sure
that no foreign material enters
the final transmission case.
Make sure that no oil gets on
the tire or wheel.

8. Install the final transmission oil fill-
er cap and its new O-ring, and
then tighten the oil filler cap.
9. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM3043
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
2. Open the front storage compart-
ment A. (See page 3-20.)TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.3. Check the coolant level through
the check window.
TIPThe coolant should be between the
minimum and maximum level marks.4. If the coolant is at or below the
minimum level mark, remove pan-
el A. (See page 6-8.)
5. Open the reservoir cap, and then
add coolant to the maximum level
mark. WARNING! Remove only
the coolant reservoir cap. Never
attempt to remove the radiator
cap when the engine is hot.
[EWA15162]
NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
