Fuel cock
1. Fuel cock
The fuel cock supplies fuel from the
tank to the carburetor while filtering it
also.
The fuel cock has three positions:
OFF
With the lever in this position, fuel will
not flow. Always return the lever to
this position when the engine is not
running.
ON
With the lever in this position, fuel
flows to the carburetor. Normal riding
is done with the lever in this position.RES
This indicates reserve. If you run out
of fuel while riding, move the lever to
this position. Fill the tank at the first
opportunity. Be sure to set the lever
back to “ON” after refueling!

Starter (choke) lever “q”
1. Starter (choke) lever
Starting a cold engine requires a
richer air-fuel mixture, which is sup-
plied by the starter (choke).
Move the lever in direction (a) to turn
on the starter (choke).
Move the lever in direction (b) to turn
off the starter (choke).

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.

Air filter element
The air filter element must be cleaned
and replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart. Have a Yamaha dealer

Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most
carburetor adjustments should be left
to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment des-
cribed in the following section, howe-
ver, may be serviced by the owner as
part of routine maintenance.
ECA10550
CAUTION:
The carburetor has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical know-
ledge may result in poor perfor-
mance of or damage to the engine.
EAU21370
Adjusting the throttle cable
free play
The throttle cable free play should
measure 4 ~ 6 mm (0.15 ~ 0.23 in) at
the throttle grip. Periodically check
the throttle cable free play and, if
necessary, adjust it as follows.
1. Throttle cable free play
NOTE:
The engine idling speed must be
correctly adjusted before checking
and adjusting the throttle cable free
play.
