4-4 If brake fluid leakage is found, ask a Yamaha dealer or
other qualified mechanic for immediate repairs. Such
leakage could indicate a hazardous condition.
CAUTION:
Brake fluid may deteriorate painted surfaces or plastic
parts. Never spill any fluid. If spilled, clean it up
immediately.

Apply the brake for several seconds. Check to see if any
brake fluid leaks out from the pipe joints or the master
cylinder.
WARNING:
CAUTION:
OIL QUANTITY:

1.0 L ( 0.220 Imp gal, 0.264 US gal)
Engine oil (See page 6-6 for details)
Make sure the engine oil is at the specified level. Add oil as
necessary.
Check the oil level in a daily manner and top it up if
necessary.

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
