Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the nec-
essary professional knowledge and ex-
perience. The adjustment described in
the following section, however, may be
serviced by the owner as part of rou-
tine maintenance.
NOTICE
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.
