6. Align:
•Reference mark “T” on the flywheel (1)
with the fixed reference mark on the
crankcase (2).
NOTE:
Check that the piston is under compression at top
dead centre (T.D.C.).
(3) Ignition timing reference mark
7. Check:
•Valve clearance
Out of specification ➔Adjust.
Valve clearance (cold):
Intake:
0.05 ~ 0.10 mm
Exhaust:
0.12 ~ 0.17 mm
8. Adjust:
•Valve clearance
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
Adjustment:
•Loosen the lock nut (1).
•Fit a thickness gauge (2) between the rocker
arm and the valve stem.
•Turn the adjuster (1) clockwise or anticlock-
wise using the special tool (2) to obtain the
required clearance.
Special tool:
P/N. 90890-01311
•Holding the adjuster firmly in place, lock tight-
en lock nut.
Lock nut:
14 Nm (1.4 mkg)
•Measure valve clearance.
If the clearance is incorrect, repeat the previ-
ous stages to achieve the required value.

•Heat engine and let it run to the number of
revs required.
Engine idle speed:
1,150 ~ 1,450 rpm
•Check that reference (1) is in the mobile field
of reference (2) on the flywheel.
Incorrect ignition timing ➔ Check the ignition
coil unit.
NOTE:
Ignition timing cannot be adjusted.

CHECKING THE FUSES
3-53
CHECKING THE FUSES
To avoid a short circuit, always turn the main
switch to "OFF" when checking or replacing a
fuse.
1. Remove:
•Seat
•Panel 1
2. Check:
•Fuse
CAUTION:
a. Connect the pocket tester to the fuse and
check it for continuity.
NOTE:
Set the pocket tester selector to “Ω
1”.
b. If the pocket tester indicates "∞", replace the
fuse.
3. Replace:
•Blown fuse
a. Turn off the ignition.
b. Install a new fuse of the correct amperage rat-
ing.
c. Turn on the switches to verify if the electrical
circuit is operational.
d. If the fuse immediately blows again, check the
electrical circuit.

WARNING
Never use a fuse with an amperage rating
other than that specified. Improvising or using
a fuse with the wrong amperage rating may
cause extensive damage to the electrical sys-
tem, cause the lighting and ignition systems
to malfunction and could possibly cause a fire.
4. Install:
•Pannel
•Seat
REPLACING THE HEADLIGHT BULBS
Low beam/high beam
1. Remove:
•Cowling screws (1)
2. Remove:
•Cowling (from the meter bracket)
NOTE:
Remove the cowling from the meter bracket by
lowering it to disengage it, and then lifting it up.
3. Remove:
•Headlight (2)
4. Disconnect:
•Headlight coupler (3)
5. Remove:
•Headlight bulb cover (4)
6. Remove:
•Headlight bulb holder (5) (by turning it
counterclockwise (a))
•Headlight bulb
WARNING
Headlight bulbs get very hot. Therefore, keep
flammable products away from a lit headlight
bulb, and do not touch the bulb until it has
cooled down.
