3) Competitors must declare their weight and display it next to their front number so that the scale person can easily see it.

4) The bore will be measured with dial calipers and the stroke with a two or three inch travel dial indicator. The following formula will be used to figure displacement;
BORE X BORE X STROKE X .7854 X 16.39 = CC OF ENGINE

5) The driver is the official entry. He/she can switch karts between heats or before the feature, but not during a race. The kart MUST carry the same number that the driver signed in with.

6) All host track rules and regulations will be adhered to by drivers in the Unlimited All-Stars. The show will be run according to their normal track procedures.
