Periodic maintenance and lubrication chart
NOTE:
The annual checks must be performed every year, except if a kilometer-based maintenance is performed
instead.
From 30000 km, repeat the maintenance intervals starting from 6000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

the engine and requires very sophisti-
cated adjustment. Therefore, all car-
buretor adjustments should be left to
a Yamaha dealer, who has the neces-
sary professional knowledge and
experience.
EAU21370

measure 4 ~ 6 mm (0.15 ~ 0.24 in) at
the throttle grip. Periodically check
the throttle cable free play and, if
necessary, adjust it as follows.
NOTE:
The engine idling speed must be
correctly adjusted before checking and
adjusting the throttle cable free play.
