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.
CAUTION:

ENGINE OIL LEVEL CHECK
If the oil level is below minimum ➔Add oil up
to maximum level.
Recommended oil:
SAE20W40SE or SAE10W30SE
Refer to the chart for selection of
the oils suited to the atmospheric
temperature.
API Standard:
API SE, SF, SG or higher grade
•Do not put in any chemical additives or use
oils with a grade of CD (a) or higher.
•Be sure not to use oils labeled “ENERGY
CONSERVING II” (b) or higher. Engine oil
also lubricates the clutch and additives
could cause clutch slippage.
•Be sure no foreign material enters the
crankcase.
4. Reassemble the oil tank cap.
Never start the engine when the oil tank is
empty.
