8Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
8Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up
any spilled fuel immediately.
8Do not refuel right after the engine has
been running and is still very hot.
8Be sure the fuel tank cap is closed secure-
ly.

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
