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-
3
rience. The adjustment described in the
following section, however, may be ser-
viced by the owner as part of routine
maintenance.
CAUTION:
The carburetor has been set and ex-
tensively tested at the Yamaha fac-
tory. Changing
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
