That's a joke before anyone gets their pantys in a bunch.
I've debated going to premix and so far haven't done it mostly for the hassle of riding on the street and carrying around oil. Plus the fact of the oil pump always injecting oil even when you run it out of fuel. I was wide open the other day coming home and didn't realize that I was low on fuel and was glad I had the injector and not premix when I had to go on reserve.
I just did the rear to front head conversion using the stock plug, cap and most of the stock hose and the fairing is in place with nothing sticking out past it to contact the wheel. It is possible so if you want some pics NSR-lover send me a PM and I'll send them to you.
