1. Engine oil drain bolt B4. Clean the oil strainer with solvent,
and then check it for damage and
replace it if necessary.
5. Check the O-ring for damage and
replace it if necessary.
6. Install the oil strainer, spring,
O-ring and engine oil drain bolts,
and then tighten the drain bolts to
the specifi ed torque.Tightening torque:
Engine oil drain bolt A:
20 Nm (2.0 m·kgf, 14.5 ft·lbf)
Engine oil drain bolt B:
20 Nm (2.0 m·kgf, 14.5 ft·lbf)TIPMake sure that the O-ring is properly
seated.
7. Refi ll with the specifi ed amount of
the recommended engine oil, and
then install and tighten the engine
oil fi ller cap.Recommended engine oil:
See page 8-1.
Oil change quantity:
0.9 L (0.95 US qt, 0.79 Imp.qt)
ECA11670
NOTICE● Do not use oils with a diesel
speci cation of “CD” or oils of
a higher quality than speci ed.
In addition, do not use oils la-
beled “ENERGY CONSERVING
II” or higher.
● Be sure no foreign material en-
ters the crankcase.
8. Start the engine, and then let
it idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the en-
gine off and check for the cause.
9. Turn the engine off, and then
check the oil level and correct it if
necessary.
10. Reset the oil change tripmeter.
(See page 3-3 for reset proce-
dures.)
TIPIf the engine oil is changed before
the oil change indicator flashes (i.e.
before the periodic oil change interval
has been reached), the oil change
tripmeter must be reset after the
oil change for the next periodic oil
change to be indicated at the correct
time.

PERIODIC MAINTENANCE AND ADJUSTMENTTIPThe air filter element should be wet
but not dripping.Recommended oil:
Yamaha foam air filter oil or other
quality foam air fi lter oil5. Insert the element into the air fi l-
ter case.
6. Install the fi lter element holder by
installing the screw.
7. Install the V-belt air filter case
cover by installing the screws.
EAU21401
Valve clearanceThe valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clear-
ance must be adjusted by a Yamaha
dealer at the intervals specifi ed in the
periodic maintenance and lubrication
chart.
EAU21384
Checking the throttle grip
free playThe throttle grip free play should mea-
sure 3 ~ 5 mm (0.12 ~ 0.20 in) at the
inner edge of the throttle grip. Periodi-
cally check the throttle grip free play
and, if necessary, have a Yamaha
dealer adjust it.ZAUM00**

Lubricating the front and rear
brake leversZAUM00**ZAUM00**
The pivoting points of the front and
rear brake levers must be lubricated
at the intervals specifi ed in the period-
ic maintenance and lubrication chart.
EAU23095
Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables should
be checked before each ride, and
the cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it.
WARNING! Damage to the outer
housing of cables may result in
internal rusting and cause inter-
ference with cable movement.
Replace damaged cables as soon
as possible to prevent unsafe
conditions.
[EWA10711]
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
EAU23114
Checking and lubricating the
throttle grip and cableThe operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specified in the periodic mainte-
nance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cov-
er is securely installed. Even though
the cover is installed correctly, it does
not completely protect the cable from
water entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.

Checking the front forkThe condition and operation of the
front fork must be checked as follows
at the intervals specifi ed in the period-
ic maintenance and lubrication chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the vehicle on a level sur-
face and hold it in an upright
position. WARNING! To avoid
injury, securely support the ve-
hicle so there is no danger of it
falling over.
[EWA10751]
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.

fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it.
EAU45511

cause danger. Therefore, the opera-
tion of the steering must be checked
as follows at the intervals specifi ed in
the periodic maintenance and lubrica-
tion chart.
1. Place the vehicle on the cen-
terstand. WARNING! To avoid
injury, securely support the ve-
hicle so there is no danger of it
falling over.
[EWA10751]
2. Hold the lower ends of the front
fork legs and try to move them
forward and backward. If any free
play can be felt, have a Yamaha
dealer check or repair the steer-
ing.
