BREAkING IN THE ENGINE
The first 600 Miles of operation should be considered the “Break-in” period and
special attention should be paid to the following points:
1. Take special care not to increase the RPM’s of engine while climbing steep
slopes. Never drive your dirt bike continuously for more than 30 miles without
increasing and decreasing the throttle.
2. The engine should be warmed up for 3-5 minutes prior to operation so all
components are lubricated sufficiently.
3. The driving speed shall not be over 25 MPH maximum during the first 300
miles of operation and not over 35 MPH maximum during the remaining 300
miles of the “Break-In” period.
