EAU40893
Transmission oil The transmission oil must be checked
for oil leakage before each ride. If any
leakage is found, have a Yamaha deal-
er check and repair the motorcycle. In
addition, the transmission oil must be
changed at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Place the motorcycle on the cen-
terstand.
2. Place an oil pan under the trans-
mission to collect the used oil.
3. Remove the transmission oil filler
cap, the transmission oil drain bolt
and its gasket to drain the oil from
the transmission.4. Install the transmission oil drain
bolt and its new gasket, and then
tighten the bolt to the specified
torque.
5. Refill with the specified amount of
the recommended transmission
oil, and then install and tighten the
oil filler cap.
NOTICE
ECA10452


In order to prevent clutch slip-
page (since the transmission oil
also lubricates the clutch), do
not mix any chemical additives.
Do not use oils with a diesel
specification of “CD” or oils of a
higher quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.


Make sure that no foreign mate-
rial enters the transmission.
6. Start the engine, and then let it idle
for several minutes while checking
the transmission for oil leakage. If
oil is leaking, immediately turn the
engine off and check for the cause.

If the lining thickness of a brake shoe is
less than 1.5 mm (0.06 in), have a
Yamaha dealer replace the brake
shoes as a set.
TIPBe sure to measure the brake lining at
the thinnest portion.
EAU41842
Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe conditions.[EWA10711]Recommended lubricant:
