Cleaning the air filter caps and
check hose
1. Check each cap at the bottom left
side of the air filter case and the
hose at the bottom of the V-belt
case for accumulated dirt or water.
2. If dirt or water is visible, remove
the hose or caps from their clamp.
3. Drain dirt or water into a proper
container.
4. Install the air filter check hose or
caps to the original position.
TIP
_
The air filter check hose or caps need
more frequent cleaning after riding in
the rain, washing the vehicle, or in case
of overturn. If the check hose or caps
are clogged, have a Yamaha dealer
service the vehicle.

Adjusting the carburetor
The carburetor is an important part of
the engine and requires very sophisti-
cated adjustment. Therefore, most car-
buretor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in
the following section, however, may be
serviced by the owner as part of routine
maintenance.

NOTICE
_
The carburetor has been set and ex-
tensively tested at the Yamaha fac-
tory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
