TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. 16. Install and tighten the engine oil tank fillercap.
17. Start the engine and let it idle for several minutes. During this time, check for oil
leakage. If any oil leaks are found, stop
the engine and check for the cause.
18. Stop the engine, wait at least ten minutes, and then check the oil level one last time.
19. Install the engine oil tank cover by install- ing the bolts.
20. Install the panel.
To change the engine oil and oil filter
1. Park the vehicle on a level surface.
2. Loosen the left and right side panels by removing the bolt as shown. 3. Remove the rear bottom panel by remov-
ing the bolts.

4. Remove the bolts, and then slide the cen-ter bottom panel rearward to remove it. 5. Follow steps 2–9 of the “To change the
engine oil” section for the oil draining pro-
cedure.
6. Remove the oil filter cartridge with an oil filter wrench. Make sure the O-ring is re-
moved together with the oil filter car-
tridge. If the O-ring remains attached to
the crankcase, oil leakage may occur.1. Rear bottom panel

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.EBU36053Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication 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. TIPIf the recommended gear oil is not available,
SAE 80W-90 API GL-4 or GL-5 hypoid gear
oil may be used instead. Checking the final gear oil level1. Park the vehicle on a level surface.
Tightening torque: Transmission oil drain bolt:20 N·m (2.0 kgf·m, 15 lb·ft)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.47 L (0.50 US qt, 0.41 Imp.qt)

EBU35112CoolantThe coolant level should be checked regular-
ly. In addition, the coolant must be changed
at the intervals specified in the periodic main-
tenance chart.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.
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.56 L (0.59 US qt, 0.49 Imp.qt)
Radiator (including all routes): 3.78 L (4.00 US qt, 3.33 Imp.qt)

4. If the coolant is at or below the minimumlevel mark, remove panel C. (See page
8-11.)
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.

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.

Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.
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.Clean the surface of the spark plug gasket
and its mating surface, and then wipe off any
grime from the spark plug threads.Specified spark plug:
