Right then so ive had a bash now...
I was right all along lol as i first suspected all the locknuts really do is take up the slack of the cable and i can imagine aid in replacing the cable.
1st thing i tried was to slacken the nuts a little which in essence ment the cable was less taught. At first the clutch feels super light ...however as common sense kicks in you realise all you are doing is taking up the slack and only engaging the the clutch a part of the way so i dont think that would benifit the clutch but only aid in slipping it. However i do wonder if your bite point is quiet high then it may give your leg a easyer time because you are using the clutch peddle to take up the slack and only the neccesery clutch point needed. Im not sure? My point is about midway and when i engage the clutch peddle i push it all the way in just seems easyer then hovering your leg etc
2nd attempt i tightened up the locknuts just to the point where the pivot arm is engaging the clutch arm. I think this is a winner. Although its not actually made the clutch any easyer...it has made it feel smoother. I think the clicks people are experiencing is the cable 1st taking up the slack..and then engaging the clutch which i can imagine gives 2 types of resistance...and being a pain lol
Other tips i can add are to make sure the path of the clutch cable are free. Mine had a hose fouling the cable path a little and also there are bracket like cable guides holding the cable. One of mine was slightly bent because of access to the coolent bottle so i straightened it up and made sure visually it was in a nice straight line (path of less resistance etc) oh and might aswell lube it up hilst your there.
Also whilst i was fettling i did that cheapo Tape/Ipod mod which involved removing cover etc by a user called Ibiza125 cheers ....

It really does only take a few mins and you will prob spend more time cleaning oily marks from the facia if you did it AFTER fettling the engine bay like i did haha. Just a tip if you are not keen on the white tape device and lead etc i got a Maplins unit which was black and i thought looked better blended in with the black etc
oh yea and i realise ive just wrote a bloody essay haha
