TIPBe sure to wipe off spilled oil on any
parts after the engine and exhaust sys-tem have cooled down.NOTICE
ECA11621

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.

Adjusting the clutch lever free
playThe clutch lever free play should mea-
sure 8.0–13.0 mm (0.31–0.51 in) as
shown. Periodically check the clutch le-
ver free play and, if necessary, adjust it
as follows.
1. To increase the clutch lever free play, turn the clutch lever free play
adjusting bolt in direction (a). To
decrease the clutch lever free play,
turn the adjusting bolt in direction
(b).TIPIf the specified clutch lever free play could be obtained as described above,
skip steps 2–5.
2. Fully turn the adjusting bolt in di- rection (a) to loosen the clutch ca-
ble.
3. Slide the rubber cover back further down the clutch cable, and then
loosen the locknut.
4. To increase the clutch lever free play, turn the clutch lever free play
adjusting nut in direction (a). To
decrease the clutch lever free play,
turn the adjusting nut in direction
(b).

Checking the brak e lever free
playThere should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re- sult in loss of control and an acci-
dent.
1. No brake lever free play

Checking and lubricating the
throttle grip and cableThe operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
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.
EAU23144
Checking and lubr icating the
brake and clutch leversThe operation of the brake and clutch
levers should be checked before each
ride, and the lever pivots should be lu-
bricated if necessary.
