We will follow the same rules as the adult HR class being an unrestricted engine. Here are the following rules:
Age 9-14. .. open clutch
19 / 56 clutch and gear rule ( no skip tooth )
 250 lb weight.
Maxxis open tires
RPM rule on the governor.
4500 RPM max
 To get to the rpm you adjust the throttle stop screw to come in before the required rpm rule. You may remove the spring on that screw and replace it with a nut so that you can keep it locked into the desired rpm.
RPM will be checked with a tach of tracks choosing
4500 RPM max.
An engine that is over the rpm mark will be disqualified. Arguing with us over what’s legal and what’s not will not be tolerated. The governors must kick in when checked.
