method is to remove the intake silencer
(RST90TF / RST90TFL / RST90TFY) or air fil-
ter case (RST90), and squirt oil into the throt-
tle bodies (RST90TF /
RST90TFY) or carburetor throats (RST90)
while the engine is running. NOTICE: Do not
simply start the engine when in storage,
starting the engine occasionally during the
storage period can cause more harm than
good. Moisture and acids form during
combustion which can actually increase
the chance for corrosion damage during
the storage period.
Surface protection
Apply a coat of wax to painted surfaces. Ap-
ply suitable protectants to the exterior of the
engine, drive track, and to other metal, plas-
tic, and rubber parts.
Battery
Remove the battery from the snowmobile.
Store it in a cool, dry place that is above 0 °C
(32 °F), but less than 30 °C (90 °F). Check the
condition of the battery once a month, and
charge it as necessary. NOTICE: Always
keep the battery charged. Storing a dis-
charged battery can cause permanent
battery damage.

Drive track
Loosen the drive track and block up the
chassis so that the track is suspended above
the ground.
V-belt
Remove the V-belt and store separately.
Storage
Store the snowmobile in a dry, well-ventilated
place out of direct sunlight. Put a fabric cover
over the snowmobile, preferably one that is
designed for it. Do not use a plastic or vinyl

cover—condensation could be trapped un-
derneath which could increase the chances
of rusting.
Returning to service after storage
When returning your snowmobile to service,
install the V-belt and battery and adjust the
drive track.
Remove the spark plugs and clean or replace
them if necessary. Perform all other pre-oper-
ation and seasonal maintenance checks list-
ed in the periodic maintenance chart.
TIP
Before installing the battery, have a Yamaha
dealer inspect and fully charge it.
For peak performance, it is recommended
that you have your snowmobile checked and
tuned by a Yamaha dealer. The dealer has
the experience and training to help you get
the maximum performance and use out of
your Yamaha snowmobile.
