I don't think the 360 has a ball, but check to make sure. Sounds like the throw out mechanism may have issues. It has three steel balls trapped between 2 plates with recesses for the balls. When you rotate one plate, the balls climb out of their pockets and push on the clutch rod. There is a short threaded rod with a lock nut that needs to be adjusted to remove the slack between the rod and the throw out. If there is clicking from the throw out there is a problem. Make sure all of this is correctly assembled. Make sure the left cover is correctly assembled with all the correct fasteners. If it is loose or has missing bolts, the throw out can push the cover away from the case instead of pushing the pressure plate away from the clutch stack. Remember that he actual distance the throw out traverses is fairly small, and even a small deflection in the components will impact the operation of the clutch. The crank arm has to be correctly orientated to the cable so it will be pulled through its full rotation. Keep in mind that the adjuster at the hand lever is only to adjust slack in the cable and its housing, and has nothing whatever to do with how the clutch works. If you bought new clutch plates, make sure their is the correct number of each, are all the correct thickness, and are in the right order. Non factory plates are often not the same thickness as OEM, though most clutch packs have a fair bit of tolerance for stack height. Sometimes it is helpful to have the right cover off to look at the clutch while you operate it.
