still fails to start, check for spark. If 
there's no spark, SEE YOUR 
DEALER.

No fuel to engine

• Make sure the fuel valve is on.
• Make sure the fuel tank contains 

fuel.

• Ice may be in the fuel line, filter or 

pump. Add isopropyl alcohol to the 
fuel system.

Poor engine 
compression

• This indicates a major engine 

problem that must be repaired before 
operating. SEE YOUR DEALER.

Engine lacks power

Fouled or defective 
spark plug(s)

• Replace the plug(s).

Fuel filter (loss of 
high RPM power)

Engine continually 
backfires

Faulty plug(s)

TROUBLESHOOTING

Suspension Troubleshooting

Problem

Solution

Rear suspension 
bottoms too easily 

• Set static sag (see page 48). Adjust torsion spring blocks or 

install optional torsion springs to achieve correct sag 
dimensions.

Rides too stiff in rear

• Check for binding suspension components and grease all 

pivot points.

• Set static sag (see page 48). Adjust torsion spring blocks or 

install optional torsion springs to achieve correct sag 
dimensions.

Too much weight 
transfer when 
climbing

• Set static sag (see page 48). Adjust torsion spring blocks or 

install optional torsion springs to achieve correct sag.

• Move limiter strap to high position (see page 50).

Too little weight 
transfer when 
climbing

• Set static sag (see page 48). Adjust torsion spring blocks or 

install optional torsion springs to achieve correct sag.

• Move limiter strap to low position (see page 50).

Front end pushes

• Check for worn skags.
• Check for binding front suspension shafts/steering 

components, grease all pivot points (elevate front of 
machine).

• Set static sag (see page 48). Adjust torsion spring blocks or 

install optional torsion springs to achieve correct sag.

• Increase IFS preload (if equipped) (see page 46).
• Move limiter strap to high position (see page 50).

Steering is heavy

• Make sure spindles and all steering components turn freely.
• See your dealer for ski alignment inspection.
• Check skags and skis for damage.
• Set static sag (see page 48).

Machine darts from 
side to side

• See your dealer for ski alignment inspection.
• Check for binding front suspension shafts/steering 

components, grease all pivot points (elevate front of 
machine).

• Check for excessive play in steering assembly (see dealer).
• Ensure skags are straight on skis.
• Set static sag (see page 48).
• Check rail slide/replace if worn (see page 104).

TROUBLESHOOTING

Drive Belt Wear/Burn

Cause

Solution 

Driving at low RPM

Drive at higher RPM. Gear the machine down. Check belt 
deflection.

Insufficient warm-up

Warm the engine at least five minutes. Take the drive belt 
off the machine in extremely cold weather and warm it up. 
Break machine loose from the snow.

Towing at low RPM

Do not tow in high gear. Do not tow in deep snow. Use fast, 
aggressive throttle to engage clutch.

Riding with high RPM 
and slow speed (8000 
RPM at 10 MPH/16 
km/h)

Lower the gear ratio. Reduce RPM. Avoid riding in high 
ambient temperatures. Check for snow ingestion.

Ice and snow build-up 
between track and 
tunnel

Warm the engine at least five minutes. Take the drive belt 
off the machine in extremely cold weather and warm it up. 
Break machine loose from the snow.

Poor engine 
performance

Check for fouled plugs or water, ice, or dirt in the gas tank 
or fuel line.

Loading machines onto 
trailers

Skis may gouge into trailers and prevent the drivetrain from 
spinning properly. Use enough speed to drive the machine 
completely onto the trailer. Push and pull it to finish 
loading if necessary.

Clutch malfunction

Inspect clutch components. See your dealer.

Slow, easy clutch 
engagement

Use fast, aggressive throttle to engage clutch.

Wrong or missing belt

Always use the recommended belt.

Improper break-in

Always break in a new belt and/or clutch by avoiding 
aggressive or high speed operation during the break-in 
period.
