On the other Hyper forum someone reported that some Loctite can erode plastic. Just reporting, have no idea is true.I guess you mean the heads, rather than the stems? I have one that often shifts but haven't worked out any way to tighten it. My only thought is to try and infuse some Loctite 601 into the ball-joint but I doubt it would last even if it worked.
Keep us posted...I'll have to try a drop of Loctite on the plastic and see. Only problem with teflon tape is I assume you'd need to actually get it into the ball-joint. Just winding it around the outside wouldn't help much if at all, though if some jammed into the gap it might work.
Well done and to Ducati for designing that in.Finally got around to pulling the rubber boots back on the stalks and right there are nuts that when tightened toward the mirror push the socket against the ball and voila the mirror adjustment is tightened up.
