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 compo-
nents to “load” (aiding the mating process) and then
“unload” (allowing components to cool). Although it
is essential to place some stress on the engine compo-
nents 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.
During the break-in period, a maximum of 1/2 throttle
is recommended; however, brief full-throttle accelera-
tions and variations in driving speeds contribute to
good engine break-in.
