Adjusting the carburetor The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in
the following section, however, may be
serviced by the owner as part of routine
maintenance.
EC000094
CAUTION:_ The carburetor has been set and ex-
tensively tested at the Yamaha fac-
tory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine. _

CAUTION:Be sure to use motor oils that do not contain anti-fric-
tion modifiers. Passenger car motor oils (often labeled
“ENERGY CONSERVING II”) contain anti-friction addi-
tives which will cause clutch and/or starter clutch slip-
page, resulting in reduced component life and poor
engine performance.
