Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate, and
the engine will return to an idle any time the
hand is removed from the throttle lever.
Before starting the engine, check the throttle to
be sure it is operating smoothly. Make sure it
returns to the idle position as soon as the lever
is released.
w
Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you
need to. This could cause an accident.
Check the operation of the throttle lever
before you start the engine. If the throttle
does not work smoothly, check for the
cause. Correct the problem before riding the
ATV or consult a Yamaha dealer.

Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke) should
not be used. The throttle should be opened
slightly.
EBU00182
Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke) turned
off.

Engine oil
The engine oil level should be checked before
each ride. In addition, the oil must be changed
at the intervals specified in the periodic mainte-
nance and lubrication chart.
Engine oil level measurement
1. Place the machine on a level surface.
2. Warm up the engine for several minutes and
stop it.
3. Wait a few minutes until the oil level settles,
remove the oil filler cap, wipe off the dipstick
clean. Insert the dipstick in the filler hole
without screwing it in.
NOTE:
Wait a few minutes until the oil level settles
before checking.
4. Remove the dipstick and inspect the oil
level.
5. The oil level should be between the maxi-
mum and minimum marks. If the level is low,
add oil to raise it to the proper level.

Be sure no foreign material enters the
crankcase.
9. Warm up the engine for several minutes at
idle speed. Check for oil leakage while
warming up.
cC
If oil leakage is found, stop the engine imme-
diately and check for the cause.

Engine air filter element and V-belt case air
filter element cleaning
Both air filter elements should be cleaned at the
specified intervals in the periodic maintenance
chart.
Engine air filter element
NOTE:
There is a check hose at the bottom of the air fil-
ter case. If dust or water collects in this hose,
empty the hose and clean the air filter element
and air filter case.
1. Remove the seat.
2. Remove the breather hose, and then loosen
the clamp screw.
3. Remove the air filter case cover by remov-
ing the screws.

NOTE:
The air filter element should be cleaned every
20-40 hours. It should be cleaned and lubricated
more often if the machine is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions. Check
the air filter case rubber joint to the carburetor
and manifold fittings for an airtight seal. Tighten
all fittings securely to avoid the possibility of
unfiltered air entering the engine.
cC
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, opera-
tion without the air filter element will affect
carburetor jetting with subsequent poor per-
formance and possible engine overheating.
