1. Oil level measurement
a. Place the motorcycle on a level place and hold it in an
upright position. Warm up the engine for several
minutes.
NOTE:
Be sure the motorcycle is positioned straight up when
checking the oil level. A slight tilt toward the side can result
in false readings.
b. With the engine stopped, with the engine stopped,
unscrew the oil filler cap/ dispstick and rest it on the
threads of the ok.
NOTE:
Wait a few minutes until the oil level settles before checking.
c. remove the oil filler cap/ dispstick, clean it with a dry
cloth and check the oil level.
NOTE:
To check the oil level the oil filler cap/ dispstick can not be
screwed, just lightly seated in place.
d. The oil level should be between the maximum and
minimum marks. If the level is low, add oil to raise it to
the indicated level, check for oil leakage. Engine oil

turn off the engine immediately so it will not seize. In
such a case go to the nearest Yamaha dealer or other
qualified mechanic for repairs.
3. After checking, tighten the check bolt to the specified
torque.
