Before installing a spark plug, the spark
plug gap should be measured with a
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.NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because 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, twistit back and forth while pushing it in.

CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:
Check each hose connection.

Check each hose and canister for
cracks or damage. Replace if dam-
aged.

Make sure that the canister breath-
er is not blocked, and if necessary,
clean it.

Engine oil and oil filter
cartridgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication 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, and then check the oil level
through the check window located
at the bottom-right side of the
crankcase.TIPThe engine oil should be between theminimum and maximum level marks. 4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
TIPCheck the O-ring for damage, and re-place it if necessary. To change the engine oil (with or
without oil filter cartridge 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 oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.1. Engine oil filler cap

TIPSkip steps 5–7 if the oil filter cartridge isnot being replaced. 5. Remove the oil filter cartridge with an oil filter wrench.
TIPAn oil filter wrench is available at aYamaha dealer.
6. Apply a thin coat of clean engine oil to the O-ring of the new oil filter
cartridge.
TIPMake sure that the O-ring is properlyseated.
7. Install the new oil filter cartridge with an oil filter wrench, and then
tighten it to the specified torque
with a torque wrench.

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.
10. Check the O-ring for damage, and replace it if necessary. 11. Install and tighten the engine oil fill-
er cap.
12. 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.
TIPAfter the engine is started, the engine
oil level warning light should go off if theoil level is sufficient.NOTICE

off and have a Yamaha dealer check
the vehicle.
13. Turn the engine off, wait a few min- utes until the oil settles, and then
check the oil level and correct it if
necessary.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU20095
To check the coolant level1. Place the vehicle on a level sur- face and hold it in an upright posi-
tion.TIP
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.

Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to theside can result in a false reading.
2. Check the coolant level in the cool- ant reservoir.
TIPThe coolant should be between theminimum and maximum level marks. 3. If the coolant is at or below the
minimum level mark, remove the
reservoir cap. WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.

mark, and then install the reservoir
cap. NOTICE: If coolant is not
available, use distilled water or
soft tap water instead. Do not
use hard water or salt water
since it is harmful to the engine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion. If water has been
added to the coolant, have a
Yamaha dealer check the anti-
freeze content of the coolant as
soon as possible, otherwise the effectiveness of the coolant will
be reduced.

To change the coolant1. Place the vehicle on a level sur- face and let the engine cool if nec-
essary.
2. Remove panel B. (See page 7-9.)
3. Place a container under the engine to collect the used coolant.
4. Remove the radiator cap retaining bolt, radiator cap retainer and radi-
ator cap. WARNING! Never at-
tempt to remove the radiator
cap when the engine is
hot.

the cooling system.
10. After the coolant is completely drained, thoroughly flush the cool-
ing system with clean tap water.
11. Install the coolant drain bolt and its new gasket, and then tighten the
bolt to the specified torque. 12. Pour the specified amount of the
recommended coolant into the ra-
diator and reservoir.
13. Install the coolant reservoir cap.
14. Install the radiator cap.
15. Start the engine, let it idle for sev- eral minutes, and then turn it off.
16. Remove the radiator cap to check the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap, radiator cap retainer and radi-
ator cap retaining bolt.
17. Check the coolant level in the res- ervoir. If necessary, remove the
