Changing the coolant
The coolant must be changed at the in-
tervals specified in the periodic mainte-
nance and lubrication chart. Have a
Yamaha dealer change the coolant.
WARNING! Never attempt to remove
the radiator cap when the engine is
hot.
[EWA10381]EAUM1642
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 air filter case cover by
removing the screws.
2. Pull the air filter element out, clean
it with solvent, and then squeeze
the remaining solvent out.
WARNING! Use only a dedicat-
ed parts cleaning solvent. To
avoid the risk of fire or explo-
sion, do not use gasoline or sol-
vents with a low flash point.
[EWA10431]
NOTICE: To avoid dam-
aging the foam material, handle
it gently and carefully, and do
not twist or wring it.
[ECA10511]
3. Apply oil of the recommended type
to the entire surface of the ele-
ment, and then squeeze the ex-
cess oil out.

4. Insert the element into the air filter
case. NOTICE: Make sure that
the air filter element is properly
seated in the air filter case. The
engine should never be operat-
ed without the air filter element
installed, otherwise the pis-
ton(s) and/or cylinder(s) may
become excessively worn.
[ECA10481]
5. Install the air filter case cover by in-
stalling the screws.

Adjusting the carburetor The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, all carbu-
retor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience.
EAU21382
Checking the throttle cable
free play The throttle cable free play should mea-
sure 1.5–3.0 mm (0.06–0.12 in) at the
throttle grip. Periodically check the
throttle cable free play and, if neces-
sary, have a Yamaha dealer adjust it.
