Break-in
There is never a more important period in the life of your
snowmobile than the break-in period. For the first
10 hours, approximately 200 km (125 mi), do not put an
excessive load on the engine. Avoid prolonged full throt-
tle operation.
Also avoid lugging the engine, such as laborious opera-
tion in wet snow. If any abnormal condition is noticed,
such as excessive vibration or noise, consult a Yamaha
dealer.
TIP
@
To ensure proper engine break-in, use a 50:1 gasoline/oil
mixture when filling the fuel tank of a new snowmobile for
the first time.
For example:
10 L of gasoline per 0.2 L of oil (1 gal of gasoline per
2.6 oz of oil) equals a 50:1 mixing ratio.
(See pages 6-1–6-2 for the recommended gasoline and
oil.)
