I modified the Z bar and the linkage to the clutch fork. The welds holding the short arm of the z-bar was carefully ground down until they it came free from the bar, then it was flipped around so it was offset the opposite direction and welded back on. The link from the z-bar to the clutch fork was then fabricated in a z-pattern as well. Worked for many years without a problem. The clearance was tight, but it worked without any interferance. I also reinforced the top part of the z-bar to prevent it from bending under higher clutch loads from a stronger clutch.
