4-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.

WARNING
_

Before installing the fuel tank,
make sure that the fuel hoses
are not damaged. If any fuel
hose is damaged, do not start
the engine but have a Yamaha

wise fuel may leak.


Make sure that the fuel hoses
are properly connected and
routed, and not pinched.


Be sure to place the fuel tank
breather hose in the original po-
sition.
_19. Install the panel, the cowling, and
the seat.
20. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.
EAU04431*
Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean the air filter element more fre-
quently if you are riding in unusually
wet or dusty areas.
1. Remove the seat. (See page 3-11
for seat removal and installation
procedures.)
2. Remove cowlings A and B as well
as panels A and B. (See pages 6-5
and 6-6 for cowling and panel re-
moval and installation proce-
dures.)3. Remove the fuel tank bolts, and

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. Be sure to wait until the engine has cooled.


After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hiss-
ing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
_CT-2AENOTE:@ If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again,
have a
Yamaha dealer check
and repair the cooling system.
