Adjusting the carburetor

NOTICE
@
● It is advisable to have a Yamaha dealer make this
adjustment.
● Make sure that the carburetor silencer is installed
before starting the engine to prevent engine dam-
age.
@
The carburetor settings may have to be changed due to
changes in air temperature and elevation, and use of
oxygenated fuels such as gasohol.
NOTICE
@
The drive chain gears and V-belt clutch must also be
adjusted when operating at altitudes above 900 m
(3,000 ft). See "Adjusting the high altitude settings"
for details.
@
Replacing the main jet
Replace the main jet according to the setting chart which
is available at a Yamaha dealer.
WARNING
@
● Never remove the drain plug or the float chamber
while the engine is hot.
Fuel will flow out from the float chamber, and could
ignite and cause injury.
● Place a rag under the carburetor before removing
the drain plug or the float chamber to catch any
spilled fuel.
●
Handle fuel with care: it is HIGHLY FLAMMABLE.
