9When disassembling the master cylinder or caliper, always replace the brake fluid. Check the brake fluid level
regularly and fill as required.
9Replace the oil seals on the inner parts of the master cylinder and caliper every two years.
9Replace the brake hoses every four years or if cracked or damaged.

Do not put in any chemical
additives. Transmission oil
also lubricates the clutch and
additives could cause clutch
slippage.

Be sure no foreign material
enters the crankcase.
6. Start the engine and warm up for
a few minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for
cause.

EAU01621*Cooling system
1. Check the coolant level in the
reservoir tank when the engine is
cold as the coolant level will vary
with engine temperature. The
coolant level should be between
the minimum and maximum
marks on the tank.
2. If the coolant level is at or below
the minimum mark, fill with tap
water (soft water) to bring the
level up to the specified level.
Change the coolant every two
years.
3. If your motorcycle overheats, see
page 6-38 for details.

Hard water or salt water is harmful
to the engine. You may use dis-
tilled water if you can’t get soft
water.

reaches the top of the radiator.
13. Fill the reservoir tank with
coolant up to specified level.
14. Install the reservoir tank cap and
check for coolant leakage.
NOTE:
If any leakage is found, ask a
Yamaha dealer to inspect the cooling
sytem.

EAU01476*Air filter
The air filter should be cleaned at the
specified intervals. It should be
cleaned more frequently if you are
riding in unusually wet or dusty
areas.
1. Remove the seat.
2. Remove cowling A and B. (See
page 6-7 for cowling removal
and installation steps.)
3. Remove the fuel tank bolt.
4. Lift the front of the fuel tank
upward and position it away from
the air filter case. (Do not
remove the fuel hoses.)

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the
engine has cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over
the radiator cap and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual
pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclock-
wise and remove it.
NOTE:
If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the rec-
ommended coolant as soon as possible.
Level is OK.
Wait until the engine
has cooled.
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system. Check the coolant level in the
reservoir tank and/or radiator.
Add coolant (See NOTE.)
Level is low, check thecooling system for leakage.Leakage.No
leakage.Ask a Yamaha dealer to inspect
and repair the cooling system.
