Break-In Procedure

A new ATV and an overhauled ATV engine require a
"break-in" period. The first month is most critical to the
life of this ATV. Proper operation during this break-in
period will help assure maximum life and performance
from the ATV.
During the first three hours of operation, always use less
than 1/2 throttle. Varying the engine RPM during the
break-in period allows the components to "load" (aiding
the mating process) and then "unload" (allowing compo-
nents to cool). Although it is essential to place some
stress on the engine components during break-in, care
should be taken not to overload the engine too often.
When the engine starts, allow it to warm up properly. Idle
the engine several minutes until the engine has reached
normal operating temperature. Do not idle the engine for
excessively long periods of time.
After the completion of the break-in period, the engine
lubricant should be changed. Other maintenance after
break-in should include checking of all prescribed adjust-
ments and tightening of all fasteners.
