Break-In - Baja motorsports WD250UR Owner's Manual

BREAK-IN

The first month is the most important in the life of your vehicle. Proper
operation during this break-in period will be helpful for assuring maximum
life and performance of your new vehicle. The following guidelines explain
proper break-in procedures.
Maximum Throttle Opening Recommendation
During the first 10 hours of operation, you should always use less than ½
throttle opening.
Vary the Engine Rotating Speed
Vary the engine rotating speed during the break-in period. This allows the
parts to "load" and then "unload" (allowing the parts to cool). Although it is
essential to place some stress on the engine components during break-in,
you must be careful not to load the engine too much.
Avoid Constant Low Rotating Speed
Operating the engine at constant low rotating speed (light load) can cause
parts to glaze and not seal properly. Allow the engine to accelerate freely
without exceeding the maximum throttle limit.
Allow the Engine Oil to Circulate Before Riding
Allow enough idling time after warm or cold engine starting. This allows the
lubricating oil to reach all critical engine components.
Observe Your Initial and Most Critical Service
The initial service (break-in maintenance) is the most important service that
your vehicle will receive. Observing a proper break-in operation, will help
engine components seal properly. Maintenance required as part of the initial
service includes proper adjustments, tightening of all bolts & nuts, and
replacement of dirty oil. Timely performance of this service will help you get
the best service life and performance of the engine.
