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

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.
