Unless the z-bar is bent, it's not your problem. I'm assuming you have adjusted the clutch linkage as far as it will go, and still have the problem?
There are two different throw-out bearings....if you have the shorter one, and it takes the longer one, that could be the problem. The pivot ball for the fork on the bellhousing may have been changed to a shorter one, also. Either one of these can cause what you are describing.
These problems start when replacing the original Borg-Beck/Long type clutches with a diaphragm type clutch. They are not the same, geometrically, and if the parts are not matched, you run into this issue....no disengagement. The diaphragm type pressure plates are a lot easier on your legs/knees, but getting all of the correct parts in a kit can be tough.
Since you dint replace the clutch yourself, there's no telling what the heck it's got in it...
