Nope, that is the Road Demon Jr. The Road Demon is a 4150 style carb with seperate inlets for each bowl.
When I was having trouble getting mine sorted out the only differnce I could see (other than main jet sizes) between a 725 Road Demon and a 750 Speed Demon was the electric choke assembly. The difference between the 725 and 650 Speed Demon was the size of the venturi in the main body.
I was quite disappointed in BG when they refused to sell the 650 main body.
