I think some issues come with using different lifting plates. Some have a very coarse thread so 3/4 turn is about half a lever in movement. I think the original items were a fine thread? The BNR clutch I have is a coarse thread, at best it’s a 1/4 turn out and that buys about 8mm of play at the bar lever before the slack is taken up. I can adjust at the bar to increase that if needs be or reduce it, I give myself about 1.5 full turns of the bar adjuster before I start. This is with the early style on the A65
Where possible and most important when using the 3 ball ramp is disconnect the cable. Remove the inspection cover on the timing side for the clutch cable make the adjustment to the rod and with a finger in the inspection hole, screw the clutch plate screw in until you can no longer apply finger movement to the 3 ball ramp, then screw it back off until you can feel just enough play. Then attach the cable and make the adjustment to remove the cable slack, however still retaining about 8mm at the bar as with the other setup.
Having run both clutch setups (albeit with aftermarket clutch lifting plates, SRM and BNR, I find this way works best for me, it’s always been fool proof and never had any clicking with it which often comes by one of two ways.
The balls are over greased and don’t roll cleanly and evenly against the ramp and thus slip. Or you’ve over extended its lift capability, the pressure from the pressure plate causes the ramp to cockle to one side and a ball drops into its start position. Least this is what I have found. Some people have had no issue with greased balls (no pun intended) but I find something like WD40 works best on mine
