Break-in recommendations
The first 600 miles (1,000 km) of riding 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 ma-
chined surfaces to polish each other and mate smoothly.
Your scooter’s 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 should be followed during the break-
in period:
Maximum throttle operation:
Initial 300 miles (600 km): ............... Less than 1/2 throttle
Up to 600 miles (1,000 km): ............ Less than 3/4 throttle
Vary the engine speed:
The engine speed should be varied and not held at a constant
rate for long periods of time. This allows the parts to be "loaded"
with pressure, and then unloaded, allowing the parts to cool.
This aids in the mating process of the engine and transmis-
sion components. It is essential that some stress be placed
on these components during break-in to ensure this mating
process. Do not, however, apply excessive load on the scooter's
drive line.
Avoid constant low speed:
Operating the engine at constant low speed (light load) can
cause parts to glaze and not seat in properly. Allow the engine
to accelerate freely through the gears, without exceeding the
recommended throttle openings.
Avoid using full throttle for the first 300 miles (500 km).
The initial service:
Observe your first and most critical service. The 200 mile (300
km) initial service is the most important service your scooter
will receive. During the break-in period all of the engine com-
ponents will have worn in and all of the other parts will have
seated in, so adjustments will be required. All fasteners will be
tightened, and the contaminated engine oil will be replaced.
NOTE: Completion of the 200 mile (300 km) initial service
will ensure optimum service life and performance from
your scooter. Do not delay in having this service performed
once your scooter reaches this mileage.
