Since I got the problem, I replaced the spark plug, engine oil, clean the air filter, and the problem still remained, so I decide to replace the coil and the clutch.
I order the clutch kit and the coil from partshark on the early of May, and I received it on 2021-06-07, and I am living in Hong Kong.πΏπ€
After viewing the video on youtube, it is quite simple to conduct the replacement.
And now, I feel the clutch level is lighter than the original one for a lot!!!π²π²π²
The engagement of clutch is precise. The noise from the clutch also disappear.
The main point is, the problem was solved!!!βοΈ
I'll keep update you guys after replacing the clutch, I hope the problem never happen again.π
