Nice. I really want a setup like that. The Goldwing flat four is absolutely perfect for a setup like that. I am so tired of dealing with FI and multiple carbs. I remember how simple my air cooled bugs with a single carb were. Not highly tuned, but dead reliable. I was about to ask if you modified the cams, I was told the stock cams had too much duration to run a single carb. From the way it runs, it is obvious you got it right.
