Changing the carburetor settings
In extremely cold weather, it is necessary to
change the carburetor settings to maintain opti-

damage.
WARNING

EWB01990

Improperly servicing or adjusting the carbu-
retors could cause them to malfunction with
the possibility of an accident, or the carbure-
tors could leak fuel, which would be a fire
hazard.

Carburetor adjustments should only be per-
formed by a Yamaha dealer. Do not attempt
to perform these procedures unless you
have mechanical knowledge and the neces-sary tools.

Do not perform this procedure while the en-
gine is hot. Place a rag under each carbure-
tor to catch any fuel. Wipe up any spilled fuel
completely.

After servicing the carburetors, always
check the throttle lever operation before op-
erating the ATV to make sure it is working
correctly.
