TIP
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.

6. Refill with the specified amount
of the recommended final trans-
mission oil, and then install and
tighten the oil filler cap. WAR-
NING! Make sure that no
foreign material enters the final
transmission case. Make sure
that no oil gets on the tire or
wheel.
[EWA11311]
7. Check the final transmission case
for oil leakage. If oil is leaking,
check for the cause.
EAUS1200
Coolant (CS50Z)
The coolant level should be checked
before each ride. In addition, the coo-
lant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAUM2102
To check the coolant level
1. Place the vehicle on a level surfa-
ce and hold it in an upright posi-
tion.
TIP
The coolant level must be chec-
ked on a cold engine since the
level varies with engine tempera-
ture.
Make sure that the vehicle is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
2. Check the coolant level through
the check window.
TIP
The coolant should be between the
minimum and maximum level marks.
1. Coolant level check window
2. Maximum level mark
3. Minimum level mark
3. If the coolant is at or below the
minimum level mark, remove the
cowling A. (See page 6-5).
4. Open the reservoir cap, and then
add coolant to the maximum
level mark. WARNING! Remove
only the coolant reservoir cap.
Never attempt to remove the
radiator cap when the engine is
hot.
[EWA15161]. NOTICE: If coolant
is not available, use distilled

water or soft tap water instead. Do
not use hard water or salt water
since it is harmful to the engine. If
water has been used instead of
coolant, replace it with coolant as
soon as possible, otherwise the
cooling system will not be protec-
ted against frost and corrosion. If
water has been added to the coo-
lant, have a Yamaha dealer check
the antifreeze content of the coo-
lant as soon as possible, otherwise
the effectiveness of the coolant will
be reduced.

Changing the coolant
The coolant must be changed at the
intervals specified in the periodic
maintenance and lubrication chart.
Have a Yamaha dealer change the
coolant. WARNING! Never attempt
