Carburetor adjustment

The carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Most adjustments
should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.
CAUTION:
@
The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-
EC000082
formance and damage may result.
