BREAK-IN (RUNNING-IN)
The first month is the most important
in the life of your vehicle. Proper oper-
ation during this break-in period will
help assure maximum life and perfor-
mance from your new vehicle. The fol-
lowing guidelines explain proper
break-in procedures.
Maximum Throttle Opening
Recommendation
During the first 10 hours of operation,
you should always use less than 1/2
throttle.
Vary the Engine Speed
Vary the engine speed during the
break-in period. This allows the parts
to “load” (aiding the mating process)
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 Speed
Operating the engine at constant low
speed (light load) can cause parts to
glaze and not seat properly. Allow the
engine to accelerate freely through
the gears, without exceeding the max-
imum recommended throttle opening.
Allow the Engine Oil to Circulate
Before Riding
Allow enough idling time after warm
or cold engine starting before revving
the engine. This allows time for the
lubricating oil to reach all critical
engine components.
Observe Your Initial and Most
Critical Service
The initial service (break-in mainte-
nance) is the most important service
your vehicle will receive. During
break-in operation, all of the engine
components will have mated together
and seated. Maintenance required as
part of the initial service includes cor-
rection of all adjustments, tightening
of all fasteners and replacement of
dirty oil. Timely performance of this
service will help make sure you get
the best service life and performance
from the engine.
