Thanks - don't know about the tank yet as it is not yet running. At the moment it is being wired and generally finished off. I imagine that the tank will be like a lot of Government projects - too expensive to fail! Though all the reports of similar setups have been very favourable. Tony Foale advised the design was probably better than the oil in frame on the original setup - apparently he used to race with an oil section at the rear of the petrol tank, and it made the bike go incredibly fast because the heat of the oil came through the skin of the tank and if he didn't finish the race as fast as possible he risked cooking the family jewels! My oil section sits a little further forward I am pleased to say. Will update fully, and not before long I hope.
