6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Safety is an obligation of the owner.
Periodic inspection, adjustment and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. The most important points of in-
spection, adjustment, and lubrication
are explained on the following pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON THE
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATION, AND INDIVIDUAL
USE, THE MAINTENANCE INTER-
VALS MAY NEED TO BE SHORT-
ENED.

@ If you are not familiar with motorcy-
cle maintenance work, have a
Yamaha dealer do it for you. @

Owner’s tool kit The owner’s tool kit is located inside
the storage compartment. (See page
3-14 for storage compartment opening
procedures.)
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.
NOTE:@ If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you. @
EW000063
WARNING
@ Modifications not approved by
Yamaha may cause loss of perfor-
mance and render the vehicle un-
safe for use. Consult a Yamaha
dealer before attempting any chang-
es. @

NOTE:@ l
The annual checks must be performed every year except if a 6,000 km or 12,000 km maintenance is performed instead.
l
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.

• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

Checking the spark plugs The spark plugs are important engine
components, which are easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plugs should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
To remove a spark plug
1. Remove the appropriate spark
plug cover (rear right or front left)
by pulling it off as shown.
2. Remove the spark plug cap.3. Remove the spark plug as shown,
with the spark plug wrench includ-
ed in the owner’s tool kit.
To check the spark plugs
1. Check that the porcelain insulator
around the center electrode on
each spark plug is a medi-
um-to-light tan (the ideal color
when the motorcycle is ridden nor-
mally).
2. Check that all spark plugs installed
in the engine have the same color.
NOTE:@ If any spark plug shows a distinctly dif-
ferent color, the engine could be defec-
tive. Do not attempt to diagnose such
problems yourself. Instead, have a
Yamaha dealer check the motorcycle. @3. Check each spark plug for elec-
trode erosion and excessive car-
bon or other deposits, and replace
it if necessary.

6To install a spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
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.
NOTE:@ 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 speci-
fied torque as soon as possible. @4. Install the spark plug cap.
5. Place the spark plug cover in the
original position.

Engine oil and oil filter
element The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Place the motorcycle on a level
surface and hold it in an upright
position.

0.7–0.8 mm
