COMPRESSION INSPECTION
Inspection:
•Turn the main switch to "ON".
•With the throttle wide open, crank the engine
until the reading on the compression gauge
stabilized.
WARNING
While operating the starter, disconnect the
spark plug cap to avoid sparks.
•Compare the pressure reading with those in
the table.
Pressure under compression:
Standard
1,100 kPa (11 kg/cm
2, 156 psi)
Minimum
900 kPa (9 kg/cm
2, 128 psi)
Maximum
1.200 kPa (12 kg/cm
2, 171 psi)
8. Check:
•Pressure under compression
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
•If the pressure reading is lower than minimum:
1) Add a few drops of oil to the cylinder through
the hole in the spark plug.
2) Measure the compression again.
3) Compare the new reading with the first, then
proceed according to the indications in the
table.

ENGINE OIL LEVEL CHECK
ENGINE OIL LEVEL CHECK
Do not put additives into the engine oil. The
latter also lubricates the clutch and additives
might cause it to slide.
WARNING
Never remove the oil tank cap when the
engine is hot. The boiling oil might spill over,
causing burns. Wait for the oil to cool to at
least 60°C (140°F) or thereabouts.
This model is fitted with a dry crankcase lubrica-
tion system. A feed pump delivers oil to the en-
gine; after fully lubricating the latter, the oil is re-
turned to the tank by a scavenge pump. The oil
level must therefore be checked in the oil tank.
1. Start the engine and warm up until the oil tem-
perature rises to approximately 60°C (140°F).
2. Idle the engine for at least 10 seconds while
keeping the motorcycle upright. After stop the
engine and check the oil level through the
level window (3) located on the left side of the
oil tank assy and(or) by oil level gauge.
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.
3. The oil level should be between the maximum
(1) and minimum (2) marks.

CHASSIS
ADJUSTING THE FRONT BRAKE
1. Adjust:
• Brake lever position
(distance abetween the brake lever and
the handlebar grip)
a. Turn the adjusting dial 1while holding the
lever pushed away from the handlebar grip
NOTE:
Align the setting on the adjusting dial with the
arrow mark 2
WARNING
After adjusting the brake lever position, make
sure the pin on the brake lever holder is firm-
ly inserted in the hole in the adjusting dial.
WARNING
A soft or spongy feeling in the brake lever can
indicate the presence of air in the brake sys-
tem. Before the vehicle is operated, the air
must be removed by bleeding the brake sys-
tem. Air in the brake system will considerably
reduce braking performance and could result
in loss of control and possibly an accident.
Therefore, inspect and, if necessary, bleed the
brake system. After adjusting the brake lever
free play, make sure that there is no brake
drag.
