Clutch problems?

You can get away with using a 10mm socket as well - that's what I used

You're right, it's an angled ring spanner. 


My money's firmly on the unbalanced carbs though, i had the same issue with mine last year so i know the exact symptoms.
Mine misbehaved in a jerky manner between 2000 and 3000rpm, above that and it was fine.
But as i ride a lot in traffic it was a bloody nightmare!

Well guys there has been a breakthrough and it's good news!    Salanair, thank you very much you absolutely nailed it. Totally slackened the cable adjusters at the lever then took off the rubber bung at the front sprocket preload adjuster to look at it. Was immensely tight, a struggle to even undo. So I put it to the spec suggested, re adjusted at the cable and my God it feels amazing now. Didn't realise how bad it was until now, felt like it was doing what I wanted not trying to fight against me. The carbs will still need to be balanced though but as for the actual problem, it was indeed the preload adjuster. Very glad it isn't the actual clutch that's the issue though. Thanks again for all the help everyone.
