Carburetor Adjustment; Idle Speed Adjustment - Yamaha 2001 YZF-R6M Owner's Manual

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-
formance and damage may result.

Idle speed adjustment

1. Start the engine and warm it up for
a few minutes at approximately
1,000 to 2,000 r/min. Occasionally
rev the engine to 4,000 to
5,000 r/min. The engine is warm
when it quickly responds to the
throttle.
2. Set the idle to the specified engine
speed by adjusting the throttle
stop screw. Turn the screw in di-
rection a to increase engine
speed and in direction b to de-
crease engine speed.
NOTE:
@
If the specified idle speed cannot be
obtained by performing the above ad-
justment, consult a Yamaha dealer.
