Adjusting The Carburetors; Adjusting The Throttle Cable Free Play; Adjusting The Valve Clearance - Yamaha VMAX VMX12P Owner's Manual

Adjusting the carburetors

The carburetors are important parts of
the engine and emission control sys-
tem, which require very sophisticated
adjustment. Therefore, all carburetor
adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience.

Adjusting the throttle cable
free play
The throttle cable free play should
measure 3–5 mm (0.12–0.20 in) at the
throttle grip. Periodically check the
throttle cable free play and, if neces-
sary, have a Yamaha dealer adjust it.

Adjusting the valve clearance

The valve clearance changes with use,
resulting in improper air-fuel mixture
and/or engine noise. To prevent this
from occurring, the valve clearance
must be adjusted by a Yamaha dealer
at the intervals specified in the periodic
maintenance and lubrication chart.
