TIP
The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.

its new gasket, and then tighten
the bolt to the specified torque.
5. Refill with the specified amount of
the recommended engine oil, and
then install and tighten the engine
oil filler cap.
NOTICE
ECA11620
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-
rial enters the crankcase.
6. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
7. Turn the engine off, wait a few min-
utes until the oil settles, and then
check the oil level and correct it if
necessary.
EAU37123
Cleaning the air filter element The air filter element should be cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
Clean or, if necessary, replace the air
filter element more frequently if you are
riding in unusually wet or dusty areas.
1. Remove panel A. (See page 6-6.)
2. Remove the air filter case cover by
removing the screws.
3. Remove the air filter element.

the air filter element.
5. Lightly tap the air filter element to
remove most of the dust and dirt,
and then blow the remaining dirt
out with compressed air on the
mesh side as shown. If the air filter
element is damaged, replace it.6. Clean the sponge material with
solvent, then squeeze the remain-
ing solvent out, and be sure to let
the sponge material dry before in-
stalling it into the air filter element.
If the sponge material is damaged,
replace it. WARNING! Use only a
dedicated parts cleaning sol-
vent. To avoid the risk of fire or
explosion, do not use gasoline
or solvents with a low flash
point.
[EWA10431]
NOTICE: To avoid
damaging the sponge material,
handle it gently and carefully,
and do not twist it.
[ECA15101]
7. Install the sponge material into the
air filter element, and then install
the air filter element into the air fil-
ter 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]
8. Install the air filter case cover by in-
stalling the screws.
9. Check the hose at the bottom of
the air filter case for accumulated
dust or water, and if necessary,
drain it by removing the clamp, and
then removing the plug.

Checking the throttle cable
free play The throttle cable free play should mea-
sure 3.0–7.0 mm (0.12–0.28 in) at the
inner edge of the throttle grip. Periodi-
cally check the throttle cable free play
and, if necessary, have a Yamaha deal-
er adjust it.
