I have always used avgas in my SFC, first for the octane and then for the lead for the valves. Being a pilot, I have always had access and there are no questions about the quality and composition. Can't run it in any of the newer bikes, but it works well for the old ones. Just keep the oil changed to prevent lead buildup in the oil. Only issue I have ever had was fiberglass slivers stopping up the small filter on the fuel inlet spigot on the side of the carb.
