Re: UK parts etc
As above, you'll struggle to find new headlights easily, replace the stock breathers with something called 'duck bill valves' it cured my misting problem, you might find an old post of mine on here somewhere with a photo of the rubber duck bill valves, but if not just google them.
I found mine in an odds and ends box at work, but you should be able to get them for a few pence on the net.
