Did anyone actually disassemble a KDSS ram to see what's inside and what is the clunk

    I know Dr. kdss is working on a replacement system, but outside of a vague writeup, has anyone actually cut a ram open and looked what is inside, and how it works?

    Yes, yes, I'm well aware of the theory and the speculation, but I'm looking for actual analysis, like this for the KDSS valve housing: https://forum.ih8mud.com/threads/anatomy-of-a-kdss-valve.1230554/
