Carburetor adjustment
The carburetor is a vital part of the engine and
requires  very  sophisticated  adjustment.  Most
adjusting  should  be  left  to  a  Yamaha  dealer
who has the professional knowledge and expe-
rience to do so. However, the idling speed may
be  performed  by  the  owner  as  a  part  of  the
usual maintenance routine.
CAUTION:
The carburetor was set at the Yamaha factory
after  many  tests.  If  the  settings  are  disturbed
by  someone  without  sufficient  technical
knowledge,  poor  engine  performance  and
damage may result.
