EBU38630Why YamalubeYAMALUBE oil is a Genuine YAMAHA Partborn of the engineers’ passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics and track testing, and have them
develop the engine together with the oil it will use. Yamalube oils take full advantage of the
base oil’s qualities and blend in the ideal ba-
lance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn-
thetic oils have their own distinct characters
and value. Yamaha’s experience gained over
many years of research and development into
oil since the 1960’s helps make Yamalube the
best choice for your Yamaha engine.

6. Check the O-ring for damage, and re-place it if necessary.
7. Refill the transmission with the specified amount of the recommended oil.
8. Install the transmission oil filler cap.
9. Start the engine and let it idle while checking for oil leakage.
10. Stop the engine and check the oil level one last time.EBU36055Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the periodic
maintenance chart.
NOTICEECB03590When checking or changing the final gear
oil, make sure that no foreign material en-
ters the final gear case. If necessary, clean
the final gear oil filler bolt and surrounding
area. Checking the final gear oil level1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its
gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.

TIPIf genuine Yamaha coolant is not available,
use an ethylene glycol antifreeze containing
corrosion inhibitors for aluminum engines and
mix with distilled water at a 1:1 ratio. NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine. To check the coolant level1. Park the vehicle on a level surface.
2. Wait for the engine to cool for an accurate
reading.
3. Look at the coolant level in the coolant
reservoir. 4. If the coolant is at or below the minimum
level mark, remove panel C. (See page
9-10.)
5. Remove the coolant reservoir cap, add coolant up to the maximum level mark,
and then install the cap. NOTICE: If cool-
ant is not available, use distilled water
or soft tap water instead. Do not use
hard water or salt water since they are
harmful to the engine. If water has
been used instead of coolant, replace

it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.
[ECB01012]
6. Install the panel when finished servicing
the vehicle. To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
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 maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine. The porcelain insulator around the center
electrode of each spark plug should be a me-
dium-to-light tan color (the ideal color when
the vehicle is ridden normally), and all spark
plugs installed in the engine should have a
similar color. If any spark plug shows a dis-
tinctly different color, the engine could be op-
erating improperly. Do not attempt to
diagnose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode ero-
sion and excessive carbon or other deposits,
it should be replaced.
Before installing a spark plug, the spark plug
gap should be measured with a wire thick-
ness gauge and, if necessary, adjusted to
specification.1. Rear axle boot

EBU38320Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
The primary air filter is easily accessed and
should be cleaned and oiled every 300–600
km (200–400 mi).
The secondary air filter is more difficult to ac-
cess, cannot be cleaned, and should be re-
placed by a Yamaha dealer every 2000–5000
km (1200–3000 mi).
TIPService the air filters more frequently when
operating in wet or dusty environments. Whenever air filter maintenance is performed:
check the air inlet for obstructions and the
air filter case for dirt and foreign matter.
 check the air filter case check hoses for dirt
or water and clean as necessary.
 check the air filter cas e joints and the rub-
ber joints to and from the throttle body for
proper fit and sealing.
 tighten all fittings securely to avoid the pos-
sibility of unfiltered air entering the engine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.
