• When disassembling the master cylinder or caliper cylinder, always replace the brake fluid. 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.

several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.
11. After the engine is started, the oil
level indicator light should go off if
the oil is at the specified level.

CAUTION:@ If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer. @12. Install the cowling.

Cooling system1. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.2. If the level is low, remove the res-
ervoir tank cover by removing the
bolts.
3. Add coolant or distilled water to
raise it to the specified level.
4. Install the reservoir tank cover and
bolts.1. Maximum level mark

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ If water is added, have a Yamaha deal-
er check the antifreeze content of the
coolant as soon as possible.
The radiator fan operation is complete-
ly automatic. It is switched on or off ac-
cording to the coolant temperature in
the radiator. @5. If your motorcycle overheats, see
page 6-42 for details.

Changing the coolant1. Remove panel C, cowling A and
cowling B. (See page 6-6 for re-
moval and installation proce-
dures.)
2. Place a container under the en-
gine.
3. Remove the radiator cap.4. Remove the water pump drain bolt
and drain the coolant from the wa-
ter pump housing.
5. Disconnect the radiator hose by
loosening the clamp and drain the
coolant completely.
6. Thoroughly flush the cooling sys-
tem with clean tap water.1. Radiator cap

67. Connect the radiator hose and
tighten the clamp.
8. Retighten the drain bolt to the
specified torque. If the gasket is
damaged, replace it.
9. Remove the reservoir tank cover
by removing the bolts.10. Remove the reservoir tank by re-
moving the bolts.
11. Remove the reservoir tank cap
and turn the tank upside down to
empty it.
12. Install the reservoir tank.
13. Fill the reservoir tank with coolant
up to the maximum level, then in-
stall the cap and cover.

16. Run the engine several minutes to
recheck the coolant level in the ra-
diator. If it is low, fill with more
coolant until it reaches the top of
the radiator.17. Check for coolant leakage.
NOTE:@ If you find any leaks, ask a Yamaha
dealer to inspect. @18. Install the panel and the cowling. Recommended anti-freeze:
High quality ethylene glycol

EW000070
WARNING
@ 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 counterclockwise 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 recom-
mended coolant as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.
