Clutch Adjustment Battle

Could it be that you have no threads of the stud exposed after you tighten the nut?
This means the tool hit and turned the nut, and did not bottom on the threaded stud.

On my bike, I don't have the washer between the nut and the lock washer. It came that way.
My guess is that when previous owner (very capable) adjusted the aligned the primary chain
and put shims behind the clutch assembly, he decided to not use the lock washer as the clutch assembly was moved out away from the centrline of bike

Ying, thanks, and I will indeed will be setting mine up just as you show here next time I use it. The more I think about it, the more I believe it was the cause of my clutch fixing nut coming loose.

That is one of the reasons why I modify the spring centers.
It allows inspection and evt tightening of the nut if it comes loose while on the road.
