Andyb,
Think I know where the 57mm system is coming from, spoke to Johnny Hackett about all this, and he had a few recommendations with the way to go, what I didn't realise was the 03 and 04 exhausts are different because of the s/arm, so quite a few 57mm system coming up for the 03 model at the moment.
T/day fairings, spoke to a friend of mine who has a 999S he bought a kit from up near me (slingshot racing I think) which was somewhere in the region of 250 quid coloured, and fits fine, so that could be sorted there.
And the new record is 156Bhp from John.... crikey!
