If it's a cable operated clutch rather than a hydraulic one ( sorry, I'm not that well up on info about the CBR600F ) the first thing I would do would be to lubricate the cable.
There are a few ways to do this but the cheapest and easiest way is to get a small plastic bag ( one of those smallish resealable food bags is ideal ) and a thick elastic band.
Undo the clutch cable from the lever on the bars and cut or poke a small hole in the plastic bag at the bottom. Push the cable through, "nipple" first and then wrap the elastic band around the cable inside the bag around the outer plastic cable sheeth so it forms a seal. Pour oil of your choice into the top of the bag and work out a way to suspend the bag on the bars so the oil doesn't pour out. Leave overnight for best results.
If it is just a case of a "dry" clutch cable, you will be amazed at the difference carrying out the above procedure makes to the clutch lever feel.
Oh....and congrats on the ride.....nice looking Hurricane.
