Being a race bike it will probably have a dynojet kit in it and also the tickover will have been increased, and that is a sympton of a hot bike with a high initial tickover.

Thanks Chris. Yes been slipping every session through all the gears when hard on the gas. I have just been reading about clutch slipping issues related to the hydraulic system and there seems to be a couple of things I can check relating to that seems as though I did change the clutch fluid at the weekend and I'm no mechanic by any means.

I'm from Yorkshire so wouldn't spend on fully synth oil unless i really had too!! I only use semi synth ( rock oil 10w / 40 ) and its never given me an problems on the DD bike. I did have really bad clutch slip once on my Cbr but that was down to clutch plates bring worn out and probably the wrong stack height. I don't know about the oil for the Ducati 600s but wouldn't see that as the problem. Might be worth checking the manual for recommended oil and stack height.

If you have an adjustable clutch lever make sure you have enough free play. Even the coffin shaped master cylinders have room for adjustment in the lever.

I will have a play with the clutch lever 1st then that sounds like the most simple thing to check 1st. I have 996 levers on it.

Could be the same problem that Banger San (Andy) maybe suffering, we were discussing it at the bike night on Monday. He suffered clutch slip at Oulton and one of his winter upgrades was to fit a later master cylinder.
These are often smaller than the original dropping the piston diameter from the original 13mm down to 12mm. Andy was saying he was getting more clutch drag when the bike was in gear with the clutch disengaged. This may well cause more heat to get into the clutch and could effect the steel drive plates, check to see if they signs of hot spots (brown patches)

I think my clutch problem my be just the free play in the lever issue as there is no play whatsoever. Anyone know how to adjust the free play on the brembo 996 type levers? I've tried ajusting the round dial on top of the lever through numbers 1-4 but not sure if this just alters the distance between the lever and the bars or if it is to adjust free play. Is there somewhere else to adjust free play? Thanks in advance

As you have found the Dial is just a span adjuster
The 996 Clutch master uses a bush that screws on to the push rod and has a small hex socket grub screw holding it in position.
Need to loosen the grub screw and screw the bush further on to the push rod
