EAU00464
Periodic inspection, adjustment and lu-
brication will keep your motorcycle in
the safest and most efficient condition
possible. Safety is an obligation of the
motorcycle owner. The maintenance
and lubrication schedule chart should
be considered strictly as a guide to
general maintenance and lubrication
intervals. YOU MUST TAKE INTO
CONSIDERATION THAT WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TIONS, AND A VARIETY OF INDIVID-
UAL USES ALL TEND TO DEMAND
THAT EACH OWNER ALTER THIS
TIME SCHEDULE TO SHORTER IN-
TERVALS TO MATCH THE ENVI-
RONMENT. The most important points
of motorcycle inspection, adjustment,
and lubrication are explained in the fol-
lowing pages.

1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plugs and tighten
them to the specified torque.
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 tightened to the specified
torque as soon as possible. @4. Install the spark plug caps.
5. Install the cowlings.

Drive chain slack checkNOTE:@ Spin the wheel several times and find
the tightest position of the chain. Check
and/or adjust the chain slack while it’s
in this tightest position. @To check the chain slack the motor-
cycle must be held straight up with both
wheels on the ground and without rider.
Check the slack at the position shown
in the illustration. Normal slack is ap-
proximately 20 ~ 35 mm. If the slack
exceeds 35 mm, adjust.

Drive chain slack adjustment1. Loosen the axle nut.
2. Loosen the locknuts on each side.
To tighten the chain, turn the chain
adjusting bolts in direction a
. To
loosen the chain, turn the adjust-
ing bolts in direction b
and push
the wheel forward. Turn each ad-
justing bolt exactly the same
amount to maintain correct axle
alignment. There are marks oneach side of the swingarm. Use
these marks to align the rear
wheel.
EC000096
CAUTION:@ Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits. @3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
