If you pick the revs up and then try to let the clutch out gently what does it actually do. What I mean is, does it get very lumpy (missing on 1 cylinder), not want to rev cleanly, or rev but the clutch not engage properly ?

It could also be a plug lead breaking down under load.
My 998 did this, and the 996 before it. Both times it was the front lead.
The bike started and ticked over just fine, but would not pull at all.

Hi and thanks for the replies. It gets lumpy and pops and farts etc and just won't pull. The clutch is engaging fine. I have used injection cleaner in the past and it sorted it out but this is a different thing altogether. It used to just loose power at about 7000 rpm. A drop of redex done the trick. I think and hope that it is the plug lead as it runs fine stationary but just won't go under load. They are the original leads too and are 13 years old. I'm going to have a look at it later when i get home. Thank's to you both for the help. let you know what happens, Cheers, Dan

Should be, but if its been sitting around, I'm thinking that there may be some crud in the fuel that could've been sucked through. ???

I may just have the answer for that one. Took Nelly and me the best part of a month to find out a similar problem on my track 916 some time ago.
The issue was a small split in one of the fuel hoses inside the tank. Anytime I was winding the throttle on the engine was about to die and would not pick up the revs. Because the fuel was being spat back in the tank, there was no tail-tail sign of what the issue could be.

If you are sitting in neutral and blip the throttle do you get any rise in revs at all?
I think my 998 would pull away and run to about 15 mph without any throttle and therefore it could be the TPS not detecting the throttle movement.
