Fuel: Premium Unleaded Fuel purchased from the Hi-Lo Gas Station located at: 475 N. Bedford Street, East Bridgewater, MA. Or VP MS98L Race Fuel.


Only standard center mounted fuel tanks can be used and can have a maximum capacity of 9 liters.  Only standard refueling jugs can be used, no quick filling systems.  Driver must be out of the kart and the engine off if any type of work is to be done on the karts.  During a pit stop, the driver and one other person are allowed on the hot pit.  Tools, fuel, chain lube, driver refreshments, etc. may be handed over the fence to the competitors and the mechanic.  Tools, fuel or any type of equipment that the competitors or the mechanics use may not be kept on Pit Lane. 

If a kart is involved in an accident, necessary repairs may be made and the kart will be allowed to re-enter the race.  


Communication with the drivers:  No radio communication is allowed between the driver and anyone in the pits. Drivers and crew can use pit boards to communicate with their drivers. Crews will have a designated area on Pit Lane where they may signal their driver. The only time a crew member may be on Pit Road is to communicate with a driver or to perform a pit stop.  Other than that, all crew/family/friends must stay behind the fence. This includes the concrete pad.  There will be no exceptions to this.


Entry speed to pit lane will be controlled either with a chicane or a narrow opening for entry to Pit Lane.  After the entry to Pit Lane, the drivers will have to maintain a safe and slow speed throughout Pit Lane.  Excessive speed and penalties for excessive Pit Lane speed will be determined by the track staff and race director. 


Refueling: Refueling must take place on the concrete pad only, not on the asphalt.  If there is to be more work done on the kart, the kart has to be moved to the East end of Pit Lane. Only refueling will take place on the concrete pad.  Two karts will fit on the pad at a time, if the pad is full and another competitor wants to refuel, they will have to wait for a spot on the pad. 


Driver changes Driver/crew conversations/kart adjustments must take place on the eastern/western portion of the Pit Lane, down past the concrete refueling pad.  


Yellow Flags

The Pits are closed during a Local Yellow and Full Course Yellow Flag Condition.  This is done to eliminate the congestion on pit lane. 


Local Yellow: A local yellow will be indicated by a non-waving yellow flag.  Passing is not allowed under a local yellow flag.  Drivers will maintain their position on the track and will drive at a reasonable reduced speed until they have passed the hazard on the track.  They will be allowed to return to normal race conditions once they have cleared the yellow flag areas.    


Full Course Yellow: A full course yellow flag condition will be indicated by a waving yellow flag at each corner worker location. The track staff will decide when a Full Course Yellow flag is needed and it usually will require the removal of the kart from the race track. Once the track is cleared, the staff will throw the green flag to resume racing. Drivers will maintain single file until the green flag is thrown and racing is resumed.


Starting Positions: Starting positions will be determined by a blind draw during the drivers meeting. The number picked will be the starting position for the race. The start will be a standing semi “LeMans” style start.  The karts will be lined up diagonally along the front straight.  They will be lined up by the number drawn during the drivers meeting. The endurance class drivers will be lined up ahead of the Sportsman class.  Drivers will be given the command to start engines and then shortly thereafter the green flag will be given.


Sportsman Competitors

Minimum Age is 15 Years old.

Much of what has been written will apply to this class with the following exceptions:


The Sportsman class will be doing driver changes and pit stops. The teams will determine how long their stints will be in the kart.


The Sportsman class will be using an equalized weight formula on their karts.  Each driver will be weighed, and the weight of the team will be averaged.  The average weight and the weight of the kart will be subtracted from 385 lbs. to determine how much, if any, weight will be added to the kart. Drivers will be weighed in their street clothes.  We will be using a kart weight of 180 lbs. For example, driver #1 weighs 165 lbs. and driver #2 weighs 185 lbs. Total driver weight is 350 lbs., which when divided by the number of drivers which in this case is (2), the average driver weight is 175 lbs.  Combined with the kart weight, this team weighs 355 lbs. and they will require an additional 30 lbs. of lead. Drivers in this class not renting a kart will have to present their kart at the starting grid with the proper amount of lead affixed to the kart. The weight has to be mounted on the kart using double nuts or single nuts w/cotter pins.  The weight cannot be on the driver.
