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

a. Warm up the engine for a few minutes.
b. Stop the engine. Place an oil pan under the engine and
remove the dipstick.
c. Remove the drain plug and drain the oil.
d. Reinstall the drain plug, check if the gasket is damaged
and lighten it to the specified torque.

6-15Before installing the spark plug, measure the electrode gap
with a wire thickness gauge and adjust the gap to
specification as necessary.
Standard spark plug:
CR7HSA (NGK) and U22FSR-U (DENSO)


Spark plug gap:
0.7 mm ( 0.028 in) Spark plug inspection
The spark plug is an important engine component and is
easy to inspect. The condition of the spark plug can indicate
the condition of the engine.
The ideal color on the white porcelain insulator around the
center electrode is a medium to light tan color for a
motorcycle that is being ridden normally. Do not attempt to
diagnose any problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You should periodically
remove and inspect the spark plug because heat and
deposits will cause the spark plug to slowly break down
and erode.
If electrode erosion becomes excessive, or if carbon and
other deposits are excessive, you should replace the spark
plug with the specified plug.NOTE:
If a torque wrench is not available when you are installing a
spark plug, a good estimate of the correct torque is 1/4 to
1/2 turn past finger tight. Have the spark plug torqued to
the correct value as soon as possible with a torque wrench.
When installing the plug, always clean the gasket surface
and use a new gasket. Wipe off any grime from the threads,
and torque the spark plug properly.
Spark plug torque:
12.5 N.m (1.25 Kgf.m, 9 lbf.ft)

After adjusting the pedal height adjust brake pedal free
play.
2. Freeplay.
The rear brake pedal free play should be adjusted to
20 ~ 30 mm (0.8 ~ 1.2 in) at the brake pedal end. Turn
the adjuster on the brake rod clockwise to reduce play
or counterclockwise to increase play.
ADVERTENCIA
Brake pedal free play should be checked whenever the
chain is adjusted or the rear wheel is removed and then
reinstalled.
If it is impossible to make proper adjustment, consult
a Yamaha dealer.
Check the operation of the brake light after adjusting
the rear brake.

Brake light switch adjustment
The rear brake light switch is activated by the brake pedal
and is properly adjusted when the brake light comes on
just before braking takes effect. To adjust the rear brake
light switch, hold the switchbody so it does not rotate while
turning the adjusting nut.
Turn the adjusting nut in direction
to make the brake
light come on earlier.
Turn the adjusting nut in direction  to make the brake
light come on later.Checking the front brake pads and rear brake shoes
A wear indicator is provided on each brake. This indicator
allows checking of brake pad/shoe wear without
disassembling the brake.
