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-

dealer, who has the necessary profes-
sional knowledge and experience.

1. Throttle cable free play
The throttle cable free play should mea-
sure 3.0–5.0 mm (0.12–0.20 in) at 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.
