I like the safety rules. Pretty much what we run in drag racing and oval racing in my area. Many of us down here don't have clutches. Therefore, we cannot rev engines up at launch, which gives us a slower but safer start. Throwing it in gear with engine revved would be, well let's just say stupid! We do require good working brakes. We allow 10-16 yr olds on the singles, and above 16 in twin classes. We start most of our kids in the single flathead class. If they have enough experience, we let them in the single OHV class. Our drag racing was designed to get these younger kids on mowers, learn the feel and handling of them, before getting to race on an oval at 17 yrs old. Glad to see this section on the site - Thanks!
