Notchy clutch engagement slip/grip

[Z2TT]

Hi.

I'm wondering what could cause this, it happens during lower revs not giving it much gas when letting off the clutch. It will grip then do like a yoyo type of thing, lurch a bit, stop then lurch a bit more then get going normally, feels like it slips/grips and then it drives fine. It's hard to explain in words. Under all other conditions it doesn't appear to slip or give any issues, just the engagement is notchy on low throttle unless your getting off the clutch very slowly.

Normally if you give it more revs and get off the clutch smoother it wont do it.

Just wondering could a worn clutch cause this or air in the lines, or pressure plate issues?

Thanks.
