Its a good frame. Small kinks here and there.
Easily iron out. My take is this, these chinese chaps has come a long way. Had my cn frame as far back as 10 yrs ago. Some friends gave me the "look", didnt really care.
Long story short, Its my 3rd chinese frame over the decade.
All of 3 of it still works not a crack, but abit dated tho.
I can only forsee more cn frame with modern geo.
With each supplier having its own mold capability (frame capabililty) .. Eg carbonda.. And trifox...and this Am831 (not revealing the supplier but search and you will find ) Etc etc.
They will only get better and matured.
As far as i can tell this am831 and 830 is pretty spot on.
As someone mentioned, if only they could make a ripley dwlink type 140mm frame.

As for your question.
What i usually do is:
1.teardown and regrease/repack everything
2.workaround what is needed.
3. Tighten up everything.
--------------------------------------------
I could have waited abit more.. For them to iron out the kinks. If its a popular frame.. Get it earlier before the carbon mould wears out..
It is what it is, for the price & its good value
This am831 rear swingarm is laterally real stiff..
Only question mark i have is the bearing longevity, however i am a pretty light guy.
