Well, there is a simple problem. The transmission rear lever must NEVER
touch the back of the transmission case. If it does, your clutch throw
action stops right there, right now! You can do whatever you want with
cable adjustment or hand lever adjustment, but you won't get the clutch
to release any further. You will just overstress all of the other
elements in the clutch. Make sure there is daylight between the lever
and the back of the transmission. If not, then adjust that little pin
near the inboard end of the transmisson lever. Careful, this is a VERY
AGRESSIVE adjustment. There is something on the order of and 8:1 ratio
between the contact pin near the pivot of the lever and the cable
attachment out at the end. As in 1 mm of adjustment at the pin leads to
nearly a cm of change out at the lever tip. This adjustment will
probably only take half a turn or so. Search the manuals. There is
probably a specification as to how far the lever should be from the
transmission housing in an unloaded position.

Hmmm. Looser, quickly, over a few days? That sounds a lot like the
cable. What is your cable status? It is made up of a helically wound
group of strands. If you break just one strand, the entire bundle then
tries to slightly unwind and it grows in length by a few mm. The cable
still works and may for a long time, but it quickly grows in length over
a few days. Eventually you break another strand and it grows some more.
Leads to a rapid increas in slack. Sound familiar?
It is a lot cheaper to experiment with a new, quality cable than to muck
around inside the gearbox.
