EBU35107Transmission oilCheck the oil level and change the transmis-
sion oil at the intervals specified in the general
maintenance and lubrication chart.
NOTICEECB02910When checking or changing the transmis-
sion oil, make sure that no foreign material
enters the transmission. If necessary,
clean the filler cap and surrounding area. To check the transmission oil level1. Park the vehicle on a level surface.
2. Remove panel B. (See page 8-11.)
3. Remove the transmission oil filler cap, wipe the dipstick clean, insert it back into
the transmission case (without screwing
it in), and then remove it again.

TIPOil will flow out immediately when the drain
bolt is loosened. Take care not to lose the
bolt. 4. After draining the oil, install the transmis-sion oil drain bolt with a new gasket.
5. Tighten the drain bolt to the specified torque. 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.

8. Check for oil leakage. If oil leakage isfound, check for the cause.EBU36061Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.
Checking the differential gear oil level 1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt
and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole.
3. If the level is low, add sufficient oil of the recommended type to raise it to the
specified level.

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.
Specified spark plug:
NGK/CR9EB1. Spark plug gap

Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.TIPIf a torque wrench is not available when in-
stalling the 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. NOTICEECB02900Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler may be damaged. The spark
plug cap may be difficult to remove be- cause the rubber seal on the end of the cap
fits tightly. To remove the spark plug cap,
simply twist it back and forth while pulling
it out; to install it, twist it back and forth
while pushing it in.
EBU35423Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
