under any circumstances, contain-
ing more than 5% Methanol, doing

oil is not available, any of the oils on
the chart below will work. Note the
temperature requirements for each
of the oils.

maximum life of your Dirt Bike
engine.

tion, do not apply more than 1/2
throttle.
2. During the next 5 hours of
operation do not apply more the
3/4 throttle
Vary the engine speed:
Make sure to vary the engine speed
during the break in period, this
allows the engine to load and un-
load which helps the parts to seat
properly. It is essential to place
some stress on the engine during
the break in process, however, too
much stress could cause damage to
the engine components. Be careful
not to load the engine too much.
Break in period
Allow oil to circulate
before riding.
Allow the Dirt Bike engine to warm
up before riding. This allows the oil
to circulate throughout the engine
which lubricates the components.
Observe your initial and
most critical mainte-
nance service

tenance ) is the most important
service for your Dirt Bike. During
the break-in time frame, all of the
engine components will have mated

ments, tightening of all fasteners
and replacement of dirty oil. Timely
performance of this maintenance
will help make sure your Dirt Bike
will have the best service life and
performance of the engine.
