Thanks for the info. It is definitely worthwhile learning about the myriad of possibilities.

One problem facing us JH600'rs is that our bikes are "under warranty" (well, ok, take that at face value). We can't yet rip the things apart. At present, we must rely on the expertise & willingness of Jialing to address this serious issue.

In fairness to the Beijing Service Centre, it appears to have tried everything possible to help me out. But it, as well, is constrained by what options it has.

Jialing (Chongqing) needs to step up to the plate. We'll see what happens in the coming week, or so.
