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-
rience. The adjustment described in the
following section, however, may be ser-
viced by the owner as part of routine
maintenance.NOTICE
ECA10550
The carburetor has been set and ex-
tensively tested at the Yamaha fac-
tory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
EAU21362
Adjusting the engine idling
speed The engine idling speed must be
checked and, if necessary, adjusted as
follows at the intervals specified in the
periodic maintenance and lubrication
chart.TIPA diagnostic tachometer is needed to
make this adjustment.1. Attach the tachometer to the spark plug lead.
2. Start the engine and warm it up for several minutes at 1000 –2000
r/min while occasionally revving it
to 4000 –5000 r/min.TIPThe engine is warm when it quickly re-
sponds to the throttle.3. Check the engine idling speed
and, if necessary, adjust it to spec-
ification by turning the throttle stop
screw. To increase the engine
idling speed, turn the screw in di- rection (a). To decrease the en-
gine idling speed, turn the screw in
