6 2. Check the coolant level in the
coolant reservoir.
NOTE:@ The coolant should be between the
minimum and maximum level marks. @
3. If the coolant is at or below the
minimum level mark, remove the
seat (See page 3-11 for seat re-
moval and installation proce-
dures.), and then open the coolant
reservoir cap.
4. Add coolant or distilled water to
raise the coolant to the specified
level, close the coolant reservoir
cap, and then install the seat.

CAUTION:l
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.
l
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the engine may not be
sufficiently cooled and the cool-
ing system will not be protected
against frost and corrosion.
l
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,
otherwise the effectiveness of
the coolant will be reduced.

Never attempt to remove the radia-
tor cap when the engine is hot.

@15. Install the radiator cap, start the
engine, let it idle for several min-
utes, and then turn it off.
16. Remove the radiator cap to check
the coolant level in the radiator. If
necessary, add sufficient coolant
until it reaches the top of the radia-
tor, and then install the radiator
cap and the cap retaining bolt.
17. Check the coolant level in the res-
ervoir. If necessary, remove the
coolant reservoir cap, add coolant
to the maximum level mark, and
then install the cap.
18. Install the panel, the cowling, and
the seat.
19. Start the engine, and then check
the vehicle for coolant leakage. If
coolant is leaking, have a Yamaha
dealer check the cooling system.

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. Antifreeze/water mixture ratio:
1:1
Recommended antifreeze:
High-quality ethylene glycol
antifreeze containing corrosion
inhibitors for aluminum engines
