Foreword
This 2006 Arctic Cat High Altitude Guidebook is
designed to reflect the most up-to-date high altitude
operation information for Model Year 2006 Arctic Cat
Snowmobiles.
Since operating a snowmobile at varying altitudes
requires changes in carburetion (carbureted models) and
in drive train components, it is very important to follow
the recommended calibration changes.
Also on carbureted models, it is important to carefully
follow the Main Jet Chart recommendations (found on a
decal beneath the hood of the snowmobile and in this
guidebook) for proper main jet selection for altitude,
temperature, and gasoline being used.

High Altitude Basic
Theory of Operation
Following are basic high altitude theories for clutching,
engine, suspension, and track.
Clutching
As altitudes changes, engine horsepower changes with it.
As you go up in altitude, the engine loses horsepower.
Because of this, the constant velocity transmission
(CVT) system needs to be changed to compensate for the
horsepower loss.
At altitudes above 5000 ft, clutch engagement RPM is
normally higher than the standard setting. This is due to
the horsepower loss at altitude as opposed to what would
be seen for horsepower at sea level. The engine will lose
peak horsepower but will also lose horsepower at
engagement speed. For this reason, higher engagement
speeds are usually needed at altitude in order to attain
acceptable acceleration. This higher engagement speed
can be attained several ways. Some of the methods will
affect other characteristics of CVT operation, so you
must be careful what you change. Drive clutch springs
are the most common way to increase engagement
speed; however, by simply changing the cam arms to a
lighter weight from the heavier sea level cam arm, you
will gain some engagement speed.
Then there are other more complicated methods such as
engagement notches and changing the position of the
cam arm center of gravity in relation to the roller. This is
called “tucking the weight” and can be used, but, like the
engagement notch, it can hurt belt life.
The driven clutch will also play a part in CVT tuning for
high altitude operation. A steeper helix angle in the
driven clutch will mean a quicker up-shift. A shallower
angle will mean a slower up-shift. If the up-shift is too
quick, due to a very steep helix, RPM will be pulled
down under the peak operating RPM of the engine
(where the horsepower is) and performance will suffer.
The engine may even bog. If you have a helix that is too
shallow, the engine may over-rev or have poor acceleration. Usually, angles shallower than the sea level calibrations work best. The driven spring will also affect driven
clutch tuning. Tighten the spring, and RPM will
increase. Loosen the spring, and RPM will decrease. The
spring should be used to fine-tune and complement the
helix selection.
Keep in mind that carburetor calibration changes for
high altitude operation will have an effect on the CVT
system and how it operates. It is important that you
understand the basics of CVT operation in order to make
the correct high altitude CVT calibration changes.

Engine
Engines generate more horsepower at sea level than they
do at higher altitudes. There are many reasons for this,
but the biggest reason is that the higher you go, less oxygen is available for the engine to use during its combustion process. Less oxygen means it needs less fuel to
obtain the correct air/fuel ratio to operate properly. This
is why carburetion changes. Less oxygen and less fuel
means that the engine is not as efficient at higher altitudes. A less efficient engine generates less horsepower.
High altitude engines operate as though they have a
lower compression ratio. The carburetors on a carbureted
model also have lower pressure applied to the float
chamber because of pressure changes in the atmosphere
between high altitude and sea level. All of these characteristics will become more evident the higher the altitude.
It will be necessary to make changes to many of the systems that support engine operation as altitude changes.
Suspension
There are many different opinions on suspension tuning
at high altitude. The different riding styles of the individual operator, the varying snow conditions, and the type
of terrain are all factors that affect the suspension. Trail
riding versus powder riding versus combination riding
will all require different suspension settings.
The normal setting for front ski suspension is as little
spring pre-load tension as possible for powder snow
riding. This will allow the skis to float across the snow
with the least amount of resistance. Trail riding will
require more spring tension to carry the varying load
more effectively. There are many different settings and
spring tensions to consider when adjusting for riding
style and snow conditions.
The rear suspension has a number of spring settings that
produce different riding characteristics.
The front arm spring and shock will also affect the ride
and handling when either on a trail or in powder snow. A
strong spring setting on this shock will cause the snowmobile to tend to “dig” more when riding in the powder
rather than climbing up on top of the snow. But, it will
work more effectively when riding on a trail. A softer
spring setting will allow the front of the rear suspension
to collapse much quicker and change the angle of the
track to the snow. A more gradual angle will tend to raise
the snowmobile up on the snow rather than digging into
it.
Track
Durometer is a measurement of how hard a rubber is.
The lugs on most tracks range between 60 and 80
durometer. On the durometer scale, the higher the number, the harder the lugs. For riding in deep powder, a
softer 60 durometer track works best. The softer rubber
allows the track to “give” a little and pack the snow creating lift rather than digging its way straight down.
When hill-climbing, the harder lug of an 80 durometer
track works the best due to penetrating the hard snow
creating more bite.
The finest tuned engine in the world is useless if it cannot convert its power potential into motion. Carefully
matching the riding requirements to the type of track will
ensure the maximum use of all available engine power.
Lug height and track durometer are the two main concerns when selecting a track for various riding styles.
Some tracks come with a dual durometer rating, such as
Arctic Cat Track (p/n 1602-137) with its 80/60 durometer rating. The lugs on this track are 80% 80 durometer
rubber, and the top 20% is made of the softer 60 durometer rubber. This track is designed to be a good all-around
track for riding mostly in deep powder but can climb the
occasional hard snow hill.
There are many variables and adjustments that are possible to the rear suspension depending on snow conditions,
riding style, and type of terrain. These adjustments can
be made to individualize the snowmobile to the riding
style of the operator.
There are tracks with lug heights from 0.750 in. up to
2.25 in. to accommodate various snow conditions. Generally, the deeper the snow, the taller the lug. It must be
noted that the installation of any deep-lug track may
reduce top end speed and promote premature wear strip
wear in marginal snow conditions.

MAJOR TUNING COMPONENTS
To assist you in selecting four major tuning components of the VM-style and TM-style carburetors, listed
below are the jet needles, needle jets, pilot jets, and piston/throttle valves (slides) on charts according to
their size.
PILOT
TUNING1
„ NOTE: The above needle jets may come in different types; for example, (159) - (166) - (480) - (224).
When selecting a new needle jet, use the correct
series or type.
JET
„ NOTE: The above chart shows the average performance of a given needle between 1/4 and 3/4 throttle. Needles are constructed in such a way that at
any given point, the needle could be richer or leaner
than the rating it has.

M-Series/King Cat
Suspension
As snow cover and riding conditions change, there are
several different adjustments that can be made to change
the ride and handling characteristics for operator preference. Located on the front suspension arm are limiter
straps. They limit the amount of “fallout” the front arm
can have. These straps may be adjusted in or out due to
conditions and riding style. The more the straps are
brought up, the more steering power the operator has due
to the amount of ski pressure.
Another adjustment that can be made on the rear suspension is the front shock spring tension. As trail conditions
change, the spring pre-load may be used to decrease the
chance of the front end “bottoming out.” With a stiffer
spring pre-load, the ride of the snowmobile will improve
on the trail but will affect the performance in the deep
powder snow. In deep powder snow, the stiffer spring
pre-load will cause the front-end to “dig” and possibly
take longer for it to plane off. There are several differentrate springs available for different riding styles and terrain conditions.
One last adjustment of note is that the ski shock spring
pre-load may be adjusted also. The ski shock springs on
most snowmobiles are set at the factory to the lightest
pre-load setting. This is due to the fact that most conditions tested are better handled with the spring pre-load
on the lightest setting. Again, there are springs with different spring rates available for operator choice and
snow conditions. If trail conditions get rough, an
increase in spring pre-load would be recommended for
both comfort and control. There is a limit as to how far
you can pre-load the springs before “coil bind” takes
effect. This is when the wire on the spring actually runs
into itself and causes binding. It would be beneficial to
refer to the Arctic Cat Service Manual for more specific
information on the settings.
Finally, track tension should be looked at to make sure
that it is not too tight to affect the efficiency of the snowmobile. With the torque sensing link, the track is actually
tightening as the suspension moves through its range of
motion causing the track to sag in the middle and rub on
the top part of the rear suspension arm. The operator
needs to experiment as to how tight the track needs to be
by first leaving it too loose and causing it to skip and
then tightening it until it does not skip any more. At this
point, you have adequate track tension, and this setting
should be used for further reference.
