formed instead.
• From 50,000 km, repeat the maintenance intervals starting from 10,000 km.
• The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
• Hydraulic brake system:
• Check the brake fluid level regularly and fill as required.
• Replace the oil seals on the inner parts of the master cylinder and caliper cylinder every two years.
• Replace the brake hoses every four years or if cracked or damaged.

SPARK PLUG INSPECTION
3-9
SPARK PLUG INSPECTION
1. Remove:
•Seat
•Fuel tank
See section “SEAT, FUEL TANK AND
REAR COWLING”.
2. Disconnect:
•Spark plug cap
3. Remove:
•Spark plug (1)
Before removing the spark plug, use com-
pressed air to blow away any dirt accumulat-
ed in the spark plug wells to prevent it from
falling into the cylinder.
When removing the spark plug, be careful not
to drop foreign objects inside the engine.
4. Inspect:
•Type of spark plug
Incorrect ➔Replace.
CAUTION:
CAUTION:
Standard spark plug:
DPR8EA-9 (N.G.K.) or DPR9EA-9 (N.G.K.)
5. Inspect:
•Electrodes (1)
Wear and tear/damage ➔Replace.
•Insulator (2)
Normal insulator (2) colour is light tan.
6. Clean the spark plug with a suitable tool and a
steel brush.
7. Measure:
•Spark plug electrode gap (a)
Use a wire or thickness gauge.
Out of specification ➔Regap.
Electrode gap:
0.8 ~ 0.9 mm

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:

CHECKING AND CHARGING THE BATTERY
ELECTRICAL SYSTEM
CHECKING AND CHARGING THE BATTERY
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
•Wear protective eye gear when handling or
working near batteries.
•Charge batteries in a well-ventilated area.
•Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
•DO NOT SMOKE when charging or han-
dling batteries.
•KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
•Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
First aid in case of bodily contact:
External
•SKIN – Wash with water.
•EYES – Flush with water for 15 minutes
and get immediate medical attention.
Internal
Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.
•This is a sealed battery. Never remove the
sealing caps because the balance
between cells will not be maintained and
battery performance will deteriorate.
•Charging time, charging amperage and
charging voltage for a MF battery are dif-
ferent from those of conventional batter-
ies. The MF battery should be charged as
explained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charg-
ing the battery.
CAUTION:

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.

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.
