TROUBLESHOOTING

This troubleshooting guide is pro-
vided to help you find the cause of
some common complaints.

COMPLAINT:
Engine is hard to start or does not
start at all.

Something is probably wrong with
the fuel system or ignition system.

FUEL SYSTEM CHECK

1. Make sure there is adequate

fuel in the fuel tank.

2. Make sure there is enough fuel

reaching the carburetor from
the fuel tank.
a. Turn the fuel valve lever to

the “ON” position.

b. Loosen the drain screw

which is located under the
carburetor. Drain the fuel
from the carburetor into a
container.

CAUTION

Failure to troubleshoot a prob-
lem correctly can damage your
ATV.

Improper repairs or adjust-
ments may damage the vehicle
instead of fixing it. Such dam-
age may not be covered under
warranty.

If you are not sure about the
proper action, consult your
Suzuki dealer about the prob-
lem.



WARNING

Draining fuel from the carbure-
tor can be hazardous.

Fuel can catch on fire if you do
not handle it properly.

When draining the carburetor,
always shut the engine off. Do
not smoke, and never drain or
refuel in an area where there
are open flames or sparks. Do
not spill the fuel or you may
create a fire hazard. Dispose of
drained fuel properly.
