FEATURES AND CONTROLS

Features

Detonation Elimination Technology (D.E.T.)

Some Polaris snowmobiles are equipped with a

detonation sensor that monitors the engine and

responds to detonation by automatically reducing

the engine timing. When activated, the

“DETONATION FLASH” indicator (A)

will flash in the lower right-hand area of

the tachometer. The activated sensor

reduces engine detonation by retarding

the ignition timing. This results in

decreased engine RPM and performance.

D.E.T. Troubleshooting

Use this chart to determine causes and solutions for detonation. If

none of these conditions exists and the sensor remains activated, see

your Polaris dealer.

Possible Cause

Solution

Poor quality fuel

Replace with higher quality fuel

Improper jetting

Verify and adjust per jetting chart

Improper engine modifications

Do not modify the engine

THE PERFECT FIT

Front Suspension Adjustments

Break in the suspension for approximately 150 miles (240 km) and

re-grease all suspension parts before fine-tuning adjustments are made.
Settings will vary from rider to rider, depending on rider weight,

vehicle speed, riding style, and trail conditions. We recommend

starting with factory settings and then customizing each adjustment

individually to suit rider preference. The machine should be

methodically tested under the same conditions after each adjustment

(trail and snow conditions, vehicle speed, riding position, etc.) until the

best ride is achieved. Adjustments should be made to one area at a

time in order to properly evaluate the change.
All snowmobile suspensions have a front and a rear suspension, each

of which has adjustment options.

Independent Front Suspension (IFS)

The IFS is made up of the skis (1),

front shocks and springs (2), and the

components that connect these

parts to both the steering, such

as the tie rods (3), and to the

machine itself, such as the

trailing arms (4). Front

suspension adjustments include

shocks, springs, toe, and

camber.
NOTE: Although the front

suspension on your machine

may not look exactly like the

illustration, it will have the

same parts and functions as

those illustrated.

IFS Adjustment Options

Shock damping (if equipped with RydeFX SOLO shocks)

Front shock spring preload

Optional springs

Optional valving (if equipped with RYDE FX

shocks)

Indy Select (if equipped)

THE PERFECT FIT

Front Suspension Adjustments

The tension at which the shock coil spring is set is called spring

preload. For the best ride, the spring preload should be set as low as

possible to use the full travel of the ski shock, with occasional light

bottoming. To determine if your machine is using full travel of the ski

shock, push the jounce bumper down as far as it will go on the shock

rod and test ride the machine. The bumper will move up on the rod in

direct relation to the amount of travel. If the shock travel is full, the

bumper will be seated at the top of the shock.

Shock Absorber Components

1. Retainer

2. Shock Rod

3. Jounce Bumper

4. Body

5. Threaded Spring Preload Adjuster Nut

Always verify ski alignment before making adjustments to the

IFS. See page 101 to check alignment. If the skis are misaligned,

see your dealer, as the camber adjustment may also be affected.
