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 oil filler cap and drain
bolt to drain the oil from the trans-
mission.4. Install the transmission oil drain
bolt, and then tighten it to the spec-
ified 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.
