As a postscript I've obtained some waterwetter (without any instructions !!!) but am going for a recommended 5% cooling solution along with using the minimum concentration of anti-freeze that I can get away with - since my bike is only for trackdays.
Here are a couple of links to go with the thread:
Waterwetter - RedLineoils Website: http://www.redlineoil.com/products_c...p?productID=53 (Some nice video's on there as well - including one on synthetic oils).
