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.
