5. If the engine oil is at or below the
minimum level mark, remove the
oil filler cap, and then add suffi-
cient oil of the recommended type
to raise it to the correct level. 6. Insert and tighten the engine oil
dipstick, and then install and tight-
en the oil filler cap.
To chan ge the en gine oil (with or
without oil filter cartri dge replace-
ment) 1. Remove cowling A. (See page 6-8.)
2. Start the engine, warm it up for several minutes, and then turn it
off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler cap, the engine oil drain bolt and its
gasket to drain the oil from the
crankcase.

for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
TIPAfter the engine is started, the engine
oil level warning light should go off if
the oil level is sufficient.NOTICE

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU47561
To check the coolant level 1. Place the vehicle on the center- stand.TIPThe coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.2. Check the coolant level in the
coolant reservoir.TIPThe coolant should be between the
minimum and maximum level marks.
3. If the coolant is at or below theminimum level mark, remove the
coolant reservoir breather hose
from the guide, and then remove

Replacing the air filter ele-
mentThe air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See page 3-18.)
2. Remove panels B and C. (See page 6-8.)
3. Remove the fuel tank bolts, and then lift the fuel tank away from
the air filter case.
4. Remove the air filter case cover by removing the screws. NOTICE:
When removin g the air filter case cover,
be careful not to al-
low forei gn o bjects to drop into
the air intake manifold .
[ECA12882]
5. Pull the air filter element out. 6. Insert a new air filter element into
the air filter case. NOTICE: Make
sure that the air filter element is
properly seated in the air filter
case. The en gine shoul d never
b e operated without the air filter
element installed , otherwise the
piston(s) an d/or cylin der(s) may
b ecome excessively worn.
[ECA10482]
7. Install the air filter case cover by
installing the screws.
8. Place the fuel tank in its original position. Make sure that the fuel
hoses are properly connected and
routed, and are not pinched. Be
sure to place the hoses in their
original position. WARNING! Be-
fore placin g the fuel tank in the
ori ginal position, make sure that
all hoses (i.e., fuel hose, fuel
tank breather hose, fuel tank
overflow hose) are not dam-
a g ed , that they are properly
connected and route d, an d that
they are not pinche d. If any hose
is damag ed , have a Yamaha
d ealer replace the hose before

The engine should be warm before
making this adjustment.
Check the engine idling speed and, if
necessary, adjust it to specification by
turning the idle adjusting screw. To in-

the engine idling speed, turn the screw
in direction (b).
