I'm sure it's a rep
The same deal with the cag clutches applies with the clone rep parts aswell.A new C1 clone clutch is $20 or less. You can put Blata or Polini springs on your clone clutch
I found it takes a keen balance to dial them in...the next step in the modification of the china clutch, is to cut a m 4 thread in the base plate at the side of the arms of the clutch in order to install small m 4 worm screws there. So you can adjust the distance of the coupling arms. The diameter of the Chinaclutches is usually 75-77mm and that is not enough for a good function. The best performance is achieved with 0.5 - 1mm distance to the bell and it can also be compensated for the wear without a small bell.
