The engine operating temperature
will vary with changes in weather and
engine load. If the needle points to
the red zone or higher, stop your
motorcycle and let the engine cool.

9 Owners are personally responsible for their vehicleÕs condition. Your motorcycleÕs vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid
leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thor-
ough visual inspection, you check the following points before each ride.
EAU00340

Cooling system1.Remove panel D. (See page 6-9
for panel removal and installation
procedures.)
2.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 maximum and minimum
marks.
3.If the level is low, add coolant or
distilled water to raise it to the
specified level.4.Install the panel.
EC000080
cCHard water or salt water is harmful
to the engine. You may use dis-
tilled water if you canÕt get soft
water.NOTE:
If water is added, have a Yamaha
dealer check the antifreeze content of
the coolant as soon as possible.If your motorcycle overheats, see
page 6-41 for details.
