wire thickness 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.
TIPIf 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.

Engine oil and oil filter
elementThe 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 vehicle on a level sur- face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Wait a few minutes until the oil set- tles, remove the engine oil tank
cap, wipe the dipstick clean, insert
it back into the oil tank (without
screwing it in), and then remove it
again to check the oil level.
WARNING! Never remove the
engine oil tank cap after
high-speed operation, other-
wise hot engine oil could spout
out and cause damage or injury.

8. Install the engine oil check bolt and gasket, and then tighten the bolt to
the specified torque.
9. Start the engine and warm it up for a few minutes. Then turn the en-
gine off and wait a few minutes to
allow the oil to settle. Use the en-
gine oil tank cap and dipstick to
confirm that the engine oil level is
correct.
To change the engine oil (with or
without oil filter element replace-
ment) 1. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine guard by re- moving the bolts. 5. Remove the engine oil tank cap
and the engine oil filler cap.
6. Remove the engine oil drain bolts and their gasket to drain the oil from the oil tank and crankcase.
7. Remove the engine oil filter ele- ment drain bolt and its gasket to
drain the oil from the oil filter ele-

TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.NOTICE


In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.

Make sure that no foreign mate-rial enters the crankcase.
13. Start the engine, and then let it idle for several minutes while checking it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
14. Turn the engine off and wait a few minutes to allow the oil to settle.
Use the engine oil tank cap and
dipstick to confirm that the engine
oil level is correct.
15. Install the engine guard by install- ing the bolts.
NOTICE
ECA11232
After changing the engine oil, make
sure to check the oil pressure as de-
scribed below.
Loosen the bleed bolt.

Start the engine and keep it
idling until oil flows out. If no oil
comes out after one minute,
turn the engine off immediately
so it will not seize. If this occurs,
have a Yamaha dealer repair the
vehicle.

After checking the oil pressure, tighten the bleed bolt to the
specified torque.
Recommended engine oil:
See page 8-1.

ment:
