Way back in the dim and distant past, on theforumthatshouldnotbenamed, I posted a thread about some tank breathers I was getting from Italy. A couple of people helpfully suggested that I make up a kit comprising the breather, valve, tubing and the bottle. Apologies for taking so long, but I now have a few of the kits available on my blog. They're not cheap (at £125, posted, to mainland UK) but the price reflects what I had to pay for the breathers and Sharpy tells me they were over £400 from Ducati
