Adjusting the carburetor
The carburetor is an important part of
the engine and its emission control sys-
tem, which requires very sophisticated
adjustment. Therefore, carburetor ad-
justments should be left to Yamaha
dealer, who has the necessary profes-
sional knowledge and experience.

Adjusting the throttle cable
free play
The throttle cable free play should
measure 0.16–0.24 in (4–6 mm) at the
throttle grip. Periodically check the
throttle cable free play and, if neces-
sary, have a Yamaha dealer adjust it.
EAU00637
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.
