13. Install and tighten the engine oil tank fillercap and the cylinder head cap.
14. Start the engine, warm it up for several minutes, and then turn it off.
15. Remove the engine oil tank filler cap, and then add sufficient oil of the recommend-
ed type to raise it to the maximum level
mark on the dipstick.
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.

5. Follow steps 2–9 of the “To change theengine 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.
TIPAn oil filter wrench is available from a Yamaha
dealer. 7. Apply a light coat of clean engine oil to
the O-ring of the new oil filter cartridge.TIPMake sure that the O-ring is properly seated.

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.

TIPGL-4 is a quality and additive rating; GL-5
rated hypoid gear oils may also be used.
 If desired, an SAE 80W-90 hypoid gear oil
may be used instead. 6. Check the oil filler bolt gasket for dam-
age, and replace it if necessary.
7. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.
EBU35111CoolantThe 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.
Tightening torque:Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.31 L (0.33 US qt, 0.28 Imp.qt)
Radiator (including all routes): 3.75 L (3.96 US qt, 3.30 Imp.qt)

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. Remove the hood. (See page 8-11.)
3. Wait for the engine to cool for an accurate reading.
4. Look at the coolant level in the coolant
reservoir. 5. If the coolant is at or below the minimum
level mark, remove the coolant reservoir
cap and add coolant to the maximum lev-
el mark. NOTICE: If coolant is not avail-
able, 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 in-
stead of coolant, replace it with cool-
ant as soon as possible, otherwise the
cooling system will not be protected

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:
