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 kit
The owner’s tool kit is located on the
bottom of the seat. (See page 3-15.)
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.
TIP
If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.

6To 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.
TIP
If 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. Install the panel.

Engine oil and oil strainer
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil strainer
cleaned at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the vehicle on the center-
stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil set-
tles, remove the engine oil filler
cap, wipe the engine oil dipstick
clean, insert it back into the oil filler
hole (without screwing it in), and
then remove it again to check the
oil level. WARNING! The muffler
and muffler protector become
very hot during use. To avoid
possible burns, let the muffler
and protector cool before re-
moving the oil filler cap.
 [EWA17810]
TIP
The engine oil should be between the
tip of the dipstick and the maximum
level mark.

tip of the dipstick and the maxi-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Check the O-ring for damage, and
replace it if necessary.
6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil and clean
the oil strainer
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. Place an oil pan under the engine
to collect the used oil.
3. Remove the engine oil filler cap
and engine oil drain bolts A and B
to drain the oil from the crankcase.
NOTICE: When removing the
engine oil drain bolt B, the O-
ring, compression spring, and
oil strainer will fall out. Take
care not to lose these parts.
[ECAT1022]
4. Clean the engine oil strainer with
solvent, and then check it for dam-
age and replace it if necessary.
5. Install the engine oil strainer, com-
pression spring, new O-ring and
engine oil drain bolt B.
TIP
Make sure that the O-ring is properly
seated.
6. Install engine oil drain bolt A and
its new gasket, and then tighten
both drain bolts to their specified
torques.
7. Refill with the specified amount of
the recommended engine oil.

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.

8. Install the final transmission oil fill-
er cap and its new O-ring, and
then tighten the oil filler cap.

Coolant
The 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.
EAU40047To check the coolant level
1. Place the vehicle on the center-
stand.
TIP
 zThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
 zMake sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in an incorrect
reading.
2. Check the coolant level in the
coolant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
