BREAK-IN (RUNNING-IN)
Maximum throttle operation
recommendation
Initial 800 km (500 miles):
less than 1/2 throttle
Up to 1600 km (1000 miles):
less than 3/4 throttle
The first 1600 km (1000 miles) are the most
important in the life of your scooter. Proper
break-in operation during this time will help
ensure maximum life and performance from
your new scooter. Proper break-in operation
allows the machined surfaces to polish each
other and mate smoothly.
Scooter reliability and performance depend on
special care and restraint exercised during the
break-in period. It is especially important that
you avoid operating the engine in a manner
which could expose the engine parts to
excessive heat.
The following guidelines explain proper break-in
procedures.
The maximum recommended throttle operation
during the break-in period:
Vary the engine speed
Avoid constant low speed
The engine speed should be varied and not
held at a constant speed. This allows the parts
to be "loaded" with pressure, and then
unloaded, allowing the parts to cool. This aids
the mating process of the parts. It is essential
that some stress be placed on the engine
components during break-in to ensure this
mating process. Do not, though, apply
excessive load on the engine.
Operating the engine at constant low speed
(light load) can cause parts to glaze and not
seat in. Allow the engine to accelerate freely
through the gears, without exceeding the
recommended maximum limits. Do not,
however, use full throttle for the first 1600 km
(1000 miles).
