They have been runing on 10% ethanol for a while in the USA, and a couple of my friends over there are having all sorts of problems with their 1998-spec R1s. It doesn't seem to cause such obvious problems with injected motors, but they both find that their carbs get messed up if they leave their bikes to stand for any length of time and their bikes won't start. I know that one of them (and he's pretty mechanically competent - he's recently built his own aeroplane) has had to take his R1 into a professional workshop at least twice to get it sorted.
