Engine Break-In; Muffler - Yamaha SnoScoot SXR2NJ Operator's Manual

Since gasoline expands as its temperature
increases, the gas tank must be filled to
its rated capacity only. Expansion room
must be maintained in the tank particu-
larly if the tank is filled with cold gaso-
line and then moved to a warm area.
! WARNING
Always fill the gas tank in a well-ven-
tilated area. Never add gasoline to
the gas tank near any open flames or
with the engine running. DO NOT
SMOKE while filling the gas tank.
Recommended Oil

NOTE: This snowmobile comes
from the factory with SAE 0W-40
synthetic oil installed.
The recommended oil to use in the
engine is 0W-40 Synthetic oil. See the
viscosity chart for details.
CAUTION
Any oil used in place of the recom-
mended oil may cause serious
engine damage.

Engine Break-In

The engine requires a short break-in
period (approximately
hours) before being subjected to heavy
load conditions or full-throttle operation.
Strict adherence to the break-in proce-
dure will contribute to optimum perfor-
mance and longevity of the engine.
During break-in, a maximum of 1/2
throttle is recommended; however, brief
full-throttle accelerations and variations
in driving speeds contribute to good
engine break-in. After the 10 hour break-
in period, the snowmobile may be taken
to an authorized Yamaha Snowmobile
dealer for a checkup and oil change. This
service is at the discretion and expense of
the snowmobile owner.

Muffler

The muffler is designed to reduce engine
noise and improve the total performance
of the engine. If the engine is run without
the muffler installed, severe engine dam-
age will result.
