TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-
tem have cooled down.NOTICE
ECA11621
In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-
er quality than specifie d. In
a ddition, do not use oils lab eled
“ENERGY CONSERVING II” or
hi gher.
Make sure that no forei gn mate-
rial enters the crankcase.
11. Check the O-ring for damage, and replace it if necessary.
12. Install and tighten the engine oil filler cap.
13. Install the cowling A.
14. Start the engine, and then let it idle for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.TIPAfter the engine is started, the engine
oil pressure warning light should go off.
NOTICE
ECA20860
If the oil pressure warnin g li ght flick-
ers or remains on even if the oil level
is correct, imme diately turn the en-
g ine off an d have a Yamaha dealer
check the vehicle.15. Turn the engine off, wait a few minutes for the oil level to settle for
an accurate reading, and then
check the oil level and correct it if
necessary.

Why Yamalu beYAMALUBE oil is a Genuine YAMAHA
Part born of the engineers’ passion
and belief that engine oil is an impor-
tant liquid engine component. We form
teams of specialists in the fields of me-
chanical engineering, chemistry, elec-
tronics and track testing, and have
them develop the engine together with
the oil it will use. Yamalube oils take full
advantage of the base oil’s qualities
and blend in the ideal balance of addi-
tives to make sure the final oil clears
our performance standards. Thus,
Yamalube mineral, semisynthetic and synthetic oils have their own distinct
characters and value. Yamaha’s expe-
rience gained over many years of re-
search and development into oil since
the 1960’s helps make Yamalube the
best choice for your Yamaha engine.

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 distilled
water 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
reservoir.
3. If the coolant is at or below the minimum level mark, remove the
coolant reservoir cap. WARNING!
Remove only the coolant reser-
voir cap. Never attempt to re-
move the ra diator cap when the
en gine is hot.

use har d water or salt water
since it is harmful to the en gine.
If water has been used instead
of coolant, replace it with cool-
ant as soon as possi ble, other-
wise the coolin g system will not

corrosion. If water has been
a dde d to the coolant, have a

Valve clearanceThe valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine
noise, and eventually engine damage.
To prevent this from occurring, have
your Yamaha dealer check and adjust
the valve clearance at regular intervals.TIPThis service must be performed when
the engine is cold.

TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.

Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be

their suitability for further use.

Spoke wheelsTo maximize the performance, durabil-
ity, and safe operation of the vehicle,
note the following points.
Check each wheel for cracks, de-
formation and other damage. If
any damage is found, have the
wheel inspected by your Yamaha
dealer. Do not attempt to repair or
straighten a bent or damaged
wheel.
Check the spokes for looseness. If
any loose spokes are found, have
the wheel adjusted by your
Yamaha dealer. Improperly tight-
ened spokes can cause wheel
misalignment.
Have the wheel balanced whenev-
er the tire or tube has been re-
placed. An unbalanced wheel can
result in adverse handling charac-
teristics and shortened tire life.
