RUN-IN PROCESS
Motorcycle engines have a lot of relative moving parts, such as pistons, piston rings, cylinder
blocks, meshing transmission gears, etc. Therefore, in the initial stage of use, the engine must be
standardized. 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: Using under the throttle level of 50% ~ 75%, the speed should be changed
frequently to avoid the motorcycle working at the same condition for a long time,
Let the engine rest and cool down for 5 ~ 10 minutes after each 1-hour work.
Do not accelerate suddenly to protect your throttle.
2. 2.5-4h stage: Using under the throttle level of 50% ~ 75% throttle and work for a long time at
the same condition.
In actual working, the throttle can be up to full level, but not more than 5 ~ 10 seconds;
3. 4-5h stage: Using under the throttle level of 75% ~ 100%
4. More than 5h: increase the speed to 50 ~ 60km/h, until the engine performance can be fully
played.
