AKRA/AKS Caged Classes
The intent of this rulebook is to provide a set of rules and procedures to race by that make it as fair as possible for all to race and be competitive. This rulebook will help establish the legality of karts and engines used at Atwater Karting Speedway. Included in the following pages will be the rules to follow during the 2019 racing season.
If at any time it is determined that these rules need modification, they may be amended to incorporate these rules. It is the hope of the Atwater Karting Speedway staff that all who participate in the karting program be there to have fun and enjoy kart racing. If a modification or an item of optional equipment is not listed specifically, it will be considered illegal and will not be allowed.
RESERVED PARTICIPATION RIGHT: Atwater Karting Speedway (AKS) reserves the right to refuse to accept the entry of any kart or participant. Furthermore AKS reserves the right to revoke or cancel any entry, or any participants claimed right to be on the track premises, if it is felt or determined that a participant or pit crew’s presence or conduct is not in the best interest of the sport of kart racing, the competitors, the spectators, and the board members of AKS.
AKS board members reserve the right to call any event if they consider it unsafe for drivers or spectators or track personnel. Board members also reserve the right to decide or change any item not covered in the rule book if it is deemed necessary.
Raceway officials will decide if your kart or the operation of said kart is legal.
All karts/drivers must go through a pre-tech inspection the first time they race at AKS. Any safety issues must be corrected and re-teched before the kart or driver will be allowed on the track. Once a kart has passed a pre-tech inspection the driver/owner is responsible for maintaining the kart in the same manner as it was inspected. Should any infraction be found at any time the driver/kart will be disqualified with a loss of awards and points for that race.
Remember, this is a family sport, be sure to involve fun and respect in your racing program.

AKRA/AKS Caged Classes engine specs will be as per IKF rule book. If any engine replacement or any engine component such as a carb is necessary, it must be with prior tech approval and both engines subject to tech. Replaced motor must be turned into tech personnel until race is over.
Engine tear downs will be done at the tech inspector’s discretion. An engine may be protested upon the deposit of $50 cash. The protester must be a driver or a crew member of the kart in the same class and have raced that event. The protester must file a written protest with a Tech official within 10 minutes of the conclusion for the feature race. The written request must be on a “Protest Request Form” and include $50 cash as a deposit. Protest request forms will be available from the track tech official. Protest forms include 10 different items that can be checked. Protester may select any 3 items that they would like checked. If in checking a motor another infraction is found but was not one of the items chosen the tech official may still rule on that item. Example: Protest Includes checking the carb bore, in taking off the carb the tech official discovers the restrictor plate has obviously been drilled out. The tech official will DQ that motor. Only the tech official and one member of the protester and protested team may enter the tech area during the tear down process if no discrepancies are found, the deposit will be forfeited to the kart owner being protested. If the protest is upheld, the deposit will be returned to the protester and all awards and points will be lost for that event. Any kart being protested must not leave the pit area until instructed to leave by the tech official. Any protested kart may deny a tear down, thus acting as a upheld protest and will lose all awards and points for that event. A protested kart must begin the tear down within 10 minutes of being notified of the protest, failure to do so will be considered an upheld protest!

The official scorer must be notified if someone other than the driver at check-in is driving the kart. This must be done prior to the start of the race. Failure to do so will result in loss of points for the night.
Total points for each scheduled event will be accumulated towards season points. We are scheduled to race 10 events. When a driver competes in all 10 events, the driver's highest 9 event scores, with the driver's lowest event score thrown out, will be used to determine the class champions.
Any driver who receives a black flag will not receive points or a trophy for that race, unless the black flag was for safety reasons. A DQ score cannot be used as a throw out night for season points thus will be counted as one of the 9 event totals.
