Just been through all this myself. As the FZX is a hydraulic clutch it will def cause you issues if there is air in the line. find out where its leaking first and address that. I had to rebuild both the master and slave cylinders. kits are cheap and not too difficult to do. On these bikes its common for the bleed nipple to leak over time (put teflon tape around it, on the thread only, dont block it, and dont over tighten!) if it looks damaged at the base, then buy a new one. Bleed the line thoroughly and you should feel a good resistance on the lever. Has the bike been sitting for a while? - It maybe that the clutch plates are stuck together.
