Adjusting The Carburetor; Adjusting The Throttle Cable Free Play; Adjusting The Valve Clearance - Yamaha TT-R230V 2005 Owner's Manual

Adjusting the carburetor

The carburetor is an important part of
the engine and requires very
sophisticated adjustment. Therefore,
most carburetor adjustments should be
left to a Yamaha dealer, who has the
necessary professional knowledge and
experience. However, the following may
be serviced by the owner as part of
routine maintenance.
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient
knowledge may result in poor
performance of or damage to the
engine.
PERIODIC MAINTENANCE AND MINOR REPAIR

free play
1.Throttle cable free play
The throttle cable free play should
measure 3 ~ 5.0 mm (0.12 ~ 0,20 in) at
the throttle grip. Periodically check the
throttle cable free play and, if necessary,
technical
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.
