Causes
Solutions
Driving at low RPM
• Drive at higher RPMs. Gear the machine down. Check
belt deflection.
Insufficient warm-up
• Warm the engine at least five minutes. Take the drive
belt off the snowmobile in extremely cold weather and
warm it up. Break snowmobile loose from the snow.
Towing at low RPM
• Do not tow in deep snow. Use fast, aggressive throttle
to engage clutch.
Riding with high RPM
and slow speed (8000
RPM/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 snowmobile in extremely cold weather and
warm it up. Break snowmobile loose from the snow.
Poor engine performance
• Check for fouled plugs and water, ice or dirt in the fuel
tank or fuel line.
Loading snowmobiles
onto trailers
• Skis may gouge into trailers and prevent the drivetrain
from spinning properly. Use enough speed to drive the
snowmobile 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.
