Running-in of a new motorcycle
The importance of correctly running in a new vehicle was mentioned in the
Foreword. The correct running-in method is as follows.
Maximum speed
The maximum speed during running-in period is shown in the table.
First 800 km
Maxi 70% of the throttle grip
< 80 Km/h
800km to 1600 km
Maxi 70% of the throttle grip
< 90 Km/h
After 1600 km
End of running-in
End of running-in
Changes of engine speed
Do not drive at a constant engine speed for a long time. For a better run-in,
increase and decrease the throttle opening frequently. Change engine speed
from time to time to let various engine parts get "bearing" pressure. When the
pressure is "unloaded", the engine parts will cool down, helping the fitting of
different parts. During the running-in period, engine load may be progressively
increased. Apply some load to engine parts to guarantee good fitting. This is
very important, but do not apply excessive load to the engine.
Avoid driving at a low speed
Running at a low engine speed (with light load) can only polish the parts
but cannot get a good running-in. So long as the upper limit of recommended
throttle opening is not exceeded, drive the vehicle in various gears with
necessary acceleration. However, never drive at the maximum throttle during
the first 1600 km.
Oil circulation before driving
After starting a warm or cold engine and before applying load or driving, let
the engine run at idle speed for an adequate time. This allows lubricant to flow
to all important engine parts, so as to reduce wearing and increase the service
life. This also helps the engine to warm-up sufficiently.
First maintenance inspection
The maintenance at the first 1000 km is the most important. During the
running-in period, all engine parts have been run-in and other parts engaged.
Then, all parts shall be adjusted, all fasteners be tightened, contaminated
engine oil be replaced and filter element be replaced.
Performing the initial service at the recommended 1000 km can guarantee
a long engine life and the best engine performance.
