The running-in process
Motorcycle engines have a lot of relatively moving parts, such as pistons, piston rings,
cylinder blocks, and transmission gears that mesh with each other. Therefore, at the initial
stage of use, the engine must be run-in to a standard. The running-in can make the moving
parts adapt to each other, correct the working gap, and form a good smooth friction surface
that can withstand larger loads. Only after standard running-in can the engine have
excellent performance and reliability.
The recommended running-in steps are as follows:
1
、
0
～
2.5h stage
：
when the motorcycle is used at 50% ~ 75% throttle, the speed should be
changed frequently to avoid the motorcycle running for a long time at the same
throttle; After working for 1 hour, let the engine cool for 5 ~ 10 minutes; Avoid rapid
acceleration, throttle can not be sudden and small.
2
、
2.5
～
4h stage
：
at 50% ~ 75% throttle, the motorcycle can run for a long time at the same
throttle. In the working process, the throttle can reach 100%, but the duration is not higher
than 5 ~ 10 seconds;
3
、
4
～
5h stage
：
use the motorcycle at 75% ~ 100% throttle.
4
、
More than 5h
：
increase the speed to 60 ~ 80km/h, until the engine performance can be
fully played.
Danger
：
When driving a motorcycle, please do not speed up regardless of the
consequences, this behavior is easy to cause engine damage, thus causing safety
accidents.Therefore, please pay attention to certain driving skills when using motorcycles.
Drive Guide
Check items before driving
1.Check the tank level
2.Check the liquid level of the hand brake oil cup
3.Check the liquid level of the foot brake oil cup
4.Check the hand brake clamp system dynamic friction plate
5.Check the foot brake clamp system dynamic friction plate
6.Check braking effect of braking system
7.Check the chain
8.Inspect rear sprocket, engine sprocket and chain guide structure
9.Check the chain guider
