1. Oil level measurement
a. Place the motorcycle on the center-
stand. Warm up the engine for several
minutes.
EUU03901
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, wait a few
minutes and then remove the oil level
gauge.
c. Wipe the oil level gauge off with a
clean rag and insert it in the filler hole
without screwing it in.

Spark plug inspection
The spark plug is an important engine
component and is easy to inspect. The con-
dition of the spark plug can indicate the
condition of the engine. The ideal color on
the white insulator around the center elec-
trode 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 re-
move and inspect the spark plug because
heat and deposits will cause the spark plug
to slowly break down and erode. If elec-
trode erosion becomes excessive, or if car-
bon and other deposits are excessive, you
should replace the spark plug with the
specified plug.

Brake light switch adjustment
The brake light switch is operated by
movement of the brake pedal. To adjust,
hold the main body of the switch so it does
not rotate and turn the adjusting nut.
Proper adjustment is achieved when the
brake light comes on just before the brake
begins to take effect.
EAH81601
Checking the brake shoes
A wear indicator is provided on each brake.
This indicator allows checking of shoe
wear without disassembling the brake.
Apply the brake and check the position of
the indicator. If the indicator reaches to the
wear limit line, ask a Yamaha dealer to re-
place the shoes.

3. Remove the drive chain. Thoroughly
clean the chain with solvent and lubri-
cate it. Reinstall the chain or store it in
a plastic bag (tied to frame for safe-
keeping).
4. Lubricate all control cables.
5. Block up the frame to raise both
wheels off the ground.
6. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from enter-
ing.
7. If storing in a humid or salt-air atmos-
phere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil
to any rubber parts or the seat cover.
8. Remove the battery and charge it.
Store it in a dry place and recharge it
once a month. Do not store the bat-
tery in an excessively warm or cold
place (less than 0°C (32°F) or more
