Checked these yet Loz? Start with the clutch lever pivot pin (h/bar end). I've had this before, the pin gets flats worn on it, giving you the jerkiness you describe. My money's on this, so it's probably cheap and easy to deal with.

Being of the female variety I have not got a clue :lol I will ask OH when he gets in from flying, and answer this, I am sure it's one of the things he said but in this house it's definitely a 'blue' job :rolleyes Will get back to you within the hour
Re: Clutch judder - Loz - 01-07-13
Ok, he has returned.... He is actually quite excited, he hadn't actually thought of that, so thanks I will let you know if it works :thumbup
Re: Clutch judder - nick crisp - 01-07-13
Oh, just checked the full thread, Mike has already mentioned this, so credit to him if it works! Sorry Mike!
Re: Clutch judder - Loz - 02-07-13
I am sorry too, I must have missed that one ! Oh is going to look after work tonight
Re: Clutch judder - Falcon 269 - 02-07-13
No apology needed, guys. I wasn't aware of the thing about flats getting worn on the pivot so that's a good call and one worth looking at more closely.
Re: Clutch judder - Loz - 03-07-13
Pivot pin is fine, still searching, maybe the clutch itself?, not causing any problem at the moment just annoying not knowing lol
Re: Clutch judder - nick crisp - 03-07-13
When I first tried just lubing the pivot pin, it made little difference but wear can be minor and difficult to see. Used a bit of wet & dry to clean it up, was much better. Also look to see if there is any "oval-ing" going on in the lever bracket where the pin goes through. I would still replace the pin first before going to the clutch end of things, as it's cheap and may still fix the problem. If this is all OK, don't jump straight to clutch internals just yet. Look at the clutch actuator shaft in the clutch cover as also suggested in this thread, including bearing and seal. If you have the facilities, you can get the bike over on it's side to remove the clutch cover (saves draining the oil at this stage). Don't do this whilst on centre stand tho', you'll over-stress the stand. You should get a new clutch cover gasket before you remove the cover tho', just in case it gets damaged during removal.

Thanks Nick, yes clutch actuator shaft is what my OH meant just couldnt think of the name! but if you disconnect the clutch cable from the actuator shaft and using force with both hands it feels perfectly smooth in operation which makes him wonder? maybe its when the clutch cable is atatched to it which sends the judder to the lever.
It has got a brand new clutch lever but looked tonight and the bushing and the pin felt and looked like new. Its not that bad just a bit annoying maybe i am being over fussy lol, i will wait until i have another FZS in front of me and play with their clutch :rolleyes Thanks for all your help much appreciated
