Owner’s manual and tool kit
You are recommended to put this owner’s man-
ual and low-pressure tire gauge in the vinyl bag
and always carry them along with the owner’s
tool kit under the seat. The service information
included in this manual is intended to provide
you, the owner, with the necessary information
for completing your own preventive maintenance
and minor repairs. The tools provided in the
owner’s tool kit are sufficient for this purpose,
except that a torque wrench is also necessary to
properly tighten nuts and bolts.
NOTE:
If you do not have a torque wrench available
during a service operation requiring one, take
your machine to a Yamaha dealer to check the
torque settings and adjust them as necessary.

Final transmission oil
The final transmission case must be checked for
oil leakage before each ride. If any leakage is
found, have a Yamaha dealer check and repair
the machine. In addition, the final transmission
oil must be changed at the intervals specified in
the periodic maintenance and lubrication chart.
Final transmission oil measurement
1. Place the machine on a level surface.
2. Remove the screw and check the oil level. It
should be up to the brim of the hole. If the
oil level is low, remove the oil filler bolt, and
then add sufficient oil of the recommended
type to raise it to the proper level.
3. Install the screw and oil filler bolt, and then
tighten them to their specified torques.we
