The only race fuel I remember for 2-strokes, specifically, is Sunoco GP2R. There are a number of fuels for both two and four stroke engines. The gasolines blended for go-karts are interesting.
The race gas manufacturers websites have a lot of info. "Race Gas WA" out of Western Australia is good. What I learned was that fuel, like cams and everything else, needs to have the right properties to make everything work at its optimum. There is no substitute for asking the experts at the fuel companies.
