Checking the spark plugsThe spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion 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 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.
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.
Specified spark plug:
NGK/LMAR9E-J
1. Spark plug gapSpark plug gap: 0.6–0.7 mm (0.024–0.028 in)
Tightening torque: Spark plug (new):18 N·m (1.8 kgf·m, 13 lb·ft)
Spark plug (after checking):
13 N·m (1.3 kgf·m, 9.6 lb·ft)

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-left side of the crank-
case.TIPThe engine oil should be between theminimum and maximum level marks. 4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
TIPCheck the oil filler cap O-ring for dam-age, and replace it if necessary.
To change the engine oil (with or
without oil filter cartridge replace-
ment)1. Remove cowling A and panel B. (See page 7-8.)
2. Start the engine, warm it up for
1. To fuel tank
2. To atmosphere
3. Throttle body
4. Charcoal canister
5. Canister breather

damage, and replace it if neces-
sary.
11. Install and tighten the oil filler 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 oil pres-
sure and coolant temperature warning
light should go off if the oil level is suffi-cient.
NOTICE
ECA22490
If the oil pressure and coolant tem-
perature warning light flickers or re-
mains on even if the oil level is
correct, immediately turn the engine
off and have a Yamaha dealer checkthe 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.
14. Install the cowling and panel.
EAUS1203
CoolantThe coolant level should be checked
regularly. In addition, the coolant must
be changed at the intervals specified in
the periodic maintenance chart.TIPIf genuine Yamaha coolant is not avail-
able, use an ethylene glycol antifreeze
containing corrosion inhibitors for alu-
minum engines and mix with distilledwater at a 1:1 ratio.
EAU20097
To check the coolant level
Since the coolant level varies with en-
gine temperature, check when the en-
gine is cold. 1. Park the vehicle on a level surface.
2. With the vehicle in an upright posi- tion, look at the coolant level in the
1. Engine oil filler cap
2. O-ring

Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (max level mark):0.25 L (0.26 US qt, 0.22 Imp.qt)
Radiator (including all routes): 2.25 L (2.38 US qt, 1.98 Imp.qt)
