I recently had my fork pivotball and slave cylinder replaced because my clutch pedal went straight to the floor, i thought it was the slave cylinder and the shop tells me its the pivot ball. I got the pivot ball and clutch line combo from czp. Before the switch/fix, the clutch would start to disengage (release from pressure plate) at around 1/3rd way down (clutch pedal) and it would catch like 1/3rd coming up from the floor. Now I push down on the clutch not even an inch and I can change gears.

The problem Im really having, is that after I shift, and have my foot completely off of the clutch pedal, and for example, going from third to fourth, with my foot completely off of the clutch pedal, i can slam down on the gas and the engine will rev higher than the transmission is going. like the clutch is slipping... but ive never had this problem before. its like the clutch isnt completely on the pressure plate. not completely engaging? :confused:

I would come up to a lil mustang and his dumba** wants to take my z head on. and I failed miserably because when i would shift, i guess it wasnt grabbing like it used to :tisk: what can I do to fix this? I know the clutch didnt go bad because sometimes its like normal where it doesnt do this, but sometimes it doesnt fully catch.

Thanks in advance!!

Clutch pedal adjustment is required. Is there any free play on the pedal? Free play on the pedal ensures the full engagement/clamping of the clutch.
