MAINTENANCE
Extended Storage
Engine and Carburetor Protection
Using a fuel stabilizer and topping off the fuel tank eliminates the need
to drain the fuel system. If you prefer to drain the fuel tank, use the
following procedure:
1. Transfer unused fuel from the fuel tank to an approved fuel container
using a siphon pump. Do not re-use fuel after storage.
2. Securely support the front of the snowmobile with a jack stand so the
machine is elevated and the engine is tilted rearward.
3. Remove the spark plug(s).
4. Rotate the engine slowly, watching the piston until it’s at bottom dead
center (BDC), the lowest position in the cylinder. On twin cylinder
models, the opposite piston will be up.
5. Pour approximately two ounces of Polaris injector oil into the spark
plug hole.
6. Wait one to two minutes and perform steps 3 to 5 on remaining
cylinders.
7. Replace the spark plugs and lower the machine to the floor.
Electrical Connections
Separate electrical connector blocks and clean corrosive build-up from
connectors. Lubricate or pack connector blocks with dielectric grease
and re-connect. See page 112 for the part numbers of Polaris products.
Replace worn or frayed electrical wire and connectors. Be sure wiring
harness is properly secured away from sharp edges, steering linkage,
moving parts, and hot exhaust parts.
