the purchase of oil that does not meet the require-
ments will affect the vehicle warranty]. Please visit
QJMOTOR dealers to buy the special engine oil for
this motorcycle. The oil viscosity should be deter-
mined according to the air temperature in the driving
area.
Running-in
Maximum speed
For any new motorcycle, during the initial 1500km
running-in period, do not allow the engine speed to
exceed the maximum speed during the running-in
period, do not suddenly accelerate, turn or brake,
and do not allow the engine speed at any gear
position to exceed 80% of the maximum speed; do
not operate with the throttle fully open.
Engine speed changes
The speed of the engine should not be kept fixed, but
should be changed from time to time to facilitate the
matching of the parts.
During the break-in period, it is necessary to apply
proper pressure to the parts of the engine to ensure
a perfect fit. But not to place excessive load on that
engine.
Avoid continuous operation at a low speed
Continued operation of the engine at a low speed
(light load) will cause excessive wear on the parts,
resulting in a poor fit. Engage all gears to accelerate
the engine as long as the recommended maximum
speed limit is not exceeded, but do not increase the
throttle to the maximum during the running-in period.
The following table lists the maximum engine
speeds during break-in
Initial 800km
Reaching 1500km
Over 1500km
Circulate the oil before driving
Before driving the motorcycle in the high tempera-
ture state and the low temperature state after the
engine is running, the engine should have sufficient
idle running time to make the oil flow to all lubricating
parts.
