NOTICE
This manual was written by the Yamaha Motor Company primarily for use by Yamaha dealers and
their qualified mechanics. It is not possible to put an entire mechanic’s education into one manual,
so it is assumed that persons using this book to perform maintenance and repairs on Yamaha
snowmobiles have a basic understanding of the mechanical concepts and procedures inherent in
snowmobile repair. Without such knowledge, attempted repairs or service to this model may render
it unfit and/or unsafe to use.
This model has been designed and manufactured to perform within certain specifications in regard
to performance and emissions. Proper service with the correct tools is necessary to ensure that the
vehicle will operate as designed. If there is any question about a service procedure, it is imperative
that you contact a Yamaha dealer for any service information changes that apply to this model. This
policy is intended to provide the customer with the most satisfaction from his vehicle and to conform
to federal environmental quality objectives.
Yamaha Motor Company, Ltd. is continually striving to improve all models manufactured by
Yamaha. Modifications and significant changes in specifications or procedures will be forwarded to
all authorized Yamaha dealers and will, where applicable, appear in future editions of this manual.
HOW TO USE THIS MANUAL
Particularly important information is distinguished in this manual by the following notations:
The Safety Alert Symbol means ATTENTION! BE ALERT! YOUR SAFETY IS
INVOLVED!
Failure to follow WARNING instructions could result in severe injury or death to
the snowmobile operator, a bystander, or a person inspecting or repairing the
snowmobile.
A CAUTION indicates special precautions that must be taken to avoid damage
to the snowmobile.
A NOTE provides key information that can make procedures easier or clearer.
MANUAL FORMAT
All of the procedures in this manual are organized in a sequential, step-by-step format. The informa-
tion has been compiled to provide the mechanic with an easy to read, handy reference that contains
comprehensive explanations of all inspection, repair, assembly, and disassembly operations.
In this revised format, the condition of a faulty component will precede an arrow symbol and the
course of action required to correct the problem will follow the symbol, e.g.,
•Bearings
Pitting/damage →Replace.
EXPLODED DIAGRAM
Each chapter provides exploded diagrams before each disassembly section to facilitate correct dis-
assembly and assembly procedures.

TUNING
CARBURETOR TUNING
The carburetors are set at the factory to run at tem-
peratures of 0 °C ~ –20 °C (32 °F ~ –4 °F) at sea
level. If the machine is to be operated under condi-
tions other than those specified above, the carbure-
tors must be properly adjusted. Special care should
be taken in carburetor setting so that the pistons
will not be damaged or will not seize.
CAUTION:
Before performing the carburetor tuning, make
sure that the following items are set to specifi-
cation.
•Engine idle speed
•Throttle cable free play
•Carburetor synchronization

Mid-range and high speed tuning
Adjustments are normally not required, but may
sometimes be necessary, depending on tempera-
tures, altitude or both.
Mid-range speed and high speed tuning (from 1/4
to full-throttle) can be done by adjusting the main
jet.
CAUTION:
Never run the engine without the air filter case
installed. Severe engine damage may result.
1. Start the engine and operate the machine under
normal conditions to make sure that the engine
operates smoothly. Stop the engine.
2. Remove:
•Spark plugs

3. Check:
•Spark plug insulator 1color
A medium to light tan color indicates normal
conditions.
Distinctly different color →Replace the main
jet.
4. The main jet should be adjusted on the basis of
the “Main jet selection chart”.
NOTE:
By checking the condition of the spark plugs, it is
easy to get some idea of the condition of the
engine. This may diagnose potential problems
before engine damage occurs.
High altitude tuning
Use the chart in CHAPTER 9 to select main jets
according to variations in elevation and tempera-
ture.
NOTE:
These jetting specifications are subject to change.
Consult the latest technical information from
Yamaha to be sure you have the most up-to-date
jetting specifications.

CMain jet whose diameter is 10% larger than standard
CAUTION:
If the air filter case is removed from the carbu-
retors, the change in pressure in the intake will
create a lean mixture that may cause severe
engine damage. The air filter case has no effect
on performance characteristics and must be
secured to the carburetors during carburetor
tuning and adjustment. Also, it must always be
in place when the engine is operated. Regularly
clean the air filter and keep it free from obstruc-
tions.
Low-speed tuning
The carburetors are built so that low speed tuning
can be done by adjusting the throttle stop screw 1.
CAUTION:
Never run the engine without the air filter case
installed. Severe engine damage may result.
1. Set the engine idle speed by turning the throttle
stop screw 1in (to increase engine speed) or
out (to decrease engine speed).
2. If low-speed performance is still poor at higher
elevations under extreme conditions, the stan-
dard pilot jets may need to be replaced. In this
way, the proper air/fuel mixture is obtained.
NOTE:
In this case, use a larger numbered pilot jet to
enrich the air/fuel mixture.

Check the cooling system, gasoline octane rating
and ignition timing. After replacing the spark plug
with a colder type, tune the carburetors again.
