Break In Procedure

A new ATV and an overhauled ATV engine require a "break-in" period. The first 10 hours
(or 200 miles) are 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 10 hours (or 200 miles) 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 components 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. Do not pull a trailer or carry heavy loads during
the 10-hour break-in period.
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.
During the break-in period, 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 completion of the break-in period, the engine oil and oil filter should be changed.
Other maintenance after break-in should include checking of all prescribed adjustments
and tightening of all fasteners.
