Each of those is a different size with the largest being 360 CCs. It's a pretty mean little engine. They are raced in unlimited opens. Most all are running 460 CC motor cycle engines or 2 strokes. Guys here certainly wouldn't consider me a purist but Kart racing is supposed to be flatheads. Lol I guess that's my rule. He's quit running the flatheads this year but at their biggest race at thanksgiving his dad called and wanted to know if I had another intake manifold as theirs broke. He said the little flatty was flying against the others buy they were on a slick indoor track and all of the horse power in the world won't help if it doesn't hook up. I still love kart racing but I'm way too old.
