We will also be looking at adding some sort of "modified" classes as well. I'm not exactly sure how we will do it for sure yet, but we will. Maybe start a "amature stock" (bone stock), stock (clutching, cdi, slip on muffler), then "modified" (porting, cams, big bores), and then the "unlimited" section. You can get air pumps that screw into the spark plug hole and tell you how much "volume" the cylinder has which in turn can tell you how large it is. Just ideas....but something that will be considered in the very near future. (Open to suggestions!)
