Safety is an obligation of the owner. Peri-
odic inspection, adjustment and lubrication
will keep your vehicle in the safest and
most efficient condition possible. The most
important points of inspection, adjustment,
and lubrication are explained on the fol-
lowing pages.
The intervals given in the periodic mainte-
nance and lubrication chart should be sim-
ply considered as a general guide under
normal riding conditions. However, DE-
PENDING ON THE WEATHER, TER-
RAIN, GEOGRAPHICAL LOCATION,
AND INDIVIDUAL USE, THE MAINTE-
NANCE INTERVALS MAY NEED TO BE
SHORTENED.

Adjusting the carburetors
The carburetors are important parts of the
engine and require very sophisticated ad-
justment. Therefore, most carburetor ad-
justments should be left to a Yamaha deal-
er, who has the necessary professional
knowledge and experience. The adjust-
ment described in the following section,
however, may be serviced by the owner as
part of routine maintenance.
EC000095
The carburetors have been set and
extensively tested at the Yamaha facto-
ry. Changing these settings without
sufficient technical knowledge may
result in poor performance of or dam-
age to the engine.
CAUTION:

Adjusting the engine idling
speed
The engine idling speed must be checked
and, if necessary, adjusted as follows at
the intervals specified in the periodic main-
tenance and lubrication chart.
NOTE:
A diagnostic tachometer is needed to
make this adjustment.
1. Attach the tachometer to the spark
plug lead.
2. Start the engine and warm it up for
several minutes at 1,000-2,000 r/min
while occasionally revving it to
4,000-5,000 r/min.
NOTE:
The engine is warm when it quickly
responds to the throttle.

erly connected and routed, and not
pinched.
Be sure to place the fuel tank breather
