Maintenance

Engine

Proper off-season preparation of the engine and fuel system is vital to

the prevention of rust and corrosion formation on precision engine

parts during storage.
Without proper storage, jet restriction can cause lean conditions and

very poor slow speed driving quality.
When preparing your snowmobile for off-season storage, we

recommend that you add fuel conditioner/stabilizer or Premium Carbon

Clean (PN2871326) to the fuel tank. Follow the instructions on the

can. Run the engine for five minutes to get additives through the entire

fuel system. Then top off the tank with fresh fuel.

NOTE:

This procedure is performed best when the front of the

machine is elevated and the engine is tilted rearward.

Storage

Off season or extended storage of your snowmobile requires you to

take preventative measures to aid against deterioration and to prolong

the useful life of many components.
Your snowmobile should be stored in a dry garage or shed, out of

direct sunlight, and covered with a fabric snowmobile cover. Plastic

tarp can cause condensation to form and may damage some

snowmobile components.
