saturday and if that dosent work then it looks like its going to be the long trip back down to tts any help would be great thanks..

I have fitted a TTS jet kit and that has worked well although I have only done 500 miles with it.
Check for air leaks between the carbs and the engine. I was told to spray a bit of WD40 round the seals with the engine idling. if the revs go up,
it means that it is sucking air (and wd40) through a gap somewhere.
R1s naturally are a bit flat around 6000 so if you have a slight problem, it is likely to be around that speed.

Are all of your slides moving freely? As my carbs protrude above my bonnet slightly, I occasionally get the front carb freezing up on me!
It would also occasionally stick, but a bit of slide-swapping soon sorted that, plus the occaional squirt of WD40 around the slide can help. Give it a
try - it costs nowt! 
Spin 'er off Well...
