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 ex-
perience 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 fac-
tory after many tests. If the settings are
disturbed by someone without sufficient
technical knowledge, poor engine perfor-
mance and damage may result.
