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.

CHECKING THE BRAKE FLUID LEVEL
3-32
INSP
ADJ
CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.
NOTE:
•Place the motorcycle on a suitable stand.
•Make sure that the motorcycle is upright.
2. Check:
•Brake fluid level
Below the minimum level mark a➔Add
the recommended brake fluid to the prop-
er level.
[A] Front brake
[B] Rear brake
WARNING
•Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
•Refill with the same type of brake fluid that
is already in the system. Mixing brake flu-
ids may result in a harmful chemical reac-
tion, leading to poor brake performance.
•When refilling, be careful that water does
not enter the reservoir. Water will signifi-
cantly lower the boiling point of the brake
fluid and could cause vapor lock.
Brake fluid may damage painted surfaces and
plastic parts. Therefore, always clean up any
spilt brake fluid immediately.
NOTE:
In order to ensure a correct reading of the brake
fluid level, make sure that the top of the reservoir
is horizontal.
CAUTION:
Recommended brake fluid:

ADJUSTING THE FRONT FORK
This front fork is equipped with spring pre-load ad-
justing bolts.
WARNING0
Always adjust both fork legs equally, other-
wise poor handling and loss of stability may
result.
Adjust the spring preload as follows.
To increase the spring preload and thereby hard-
en the suspension, turn the adjusting bolt on each
fork leg in direction a. To decrease the spring
preload and thereby soften the suspension, turn
the adjusting bolt on each fork leg in direction b.
