and ending in December.  During August the race track will not have point races unless a makeup race is needed.

All drivers must register and complete the appropriate track forms prior to entering the track.  If the driver is a minor, a birth certificate and a Parent or Legal Guardian consent form must also be submitted.  All drivers must be signed in: meaning , registered and paid for all classes entered, prior to entering the track.


MCS will run practice, 2-10 lap heats and a 15 lap feature. (Rookies will be 2-5 lap heats and an 8 lap feature and JR 1 will run 2-5 lap heats and a 10 lap feature)  When you sign in for your class, you will draw a pill for the 1st heat lineup.  The 2nd heat will be a reverse of the 1st drawing.  The finishing order of each heat will be awarded points that will determine where you line up in the feature ONLY! Trophies will be awarded in the feature only. Points awarded in the heat do NOT count towards your points total. Championships will be based off of point from features ONLY! The 2 heats are to determine the line up for the feature & give the racers more racing for their money.


Any classes having over 15 entries will be split into 2 groups (A & B).

All karts must be safety inspected and have an inspection sticker visible before entering the track.

Wolf plates MUST be installed & safety wired.

WKA mufflers are mandatory

FKA carburetors are legal

Rookie & JR 1 must have loop bumper


All weights on kart must be painted white with the kart’s racing number on each weight.  The weight must be securely bolted to the kart frame or the seat.  Weight may NOT be bolted or tied to the kart body work.

Numbers must be displayed on 3 out of the four sides of the kart. The front is optional but rear and both sides are mandatory.  The numbers must be in contrasting color and be visible for scoring purposes.  If the scorekeeper cannot read your numbers you will not be scored.

No overhead spoilers permitted.

All karts must have rear bumpers.  Please see “classes” section of this rule book for additional information.

All karts with driver must meet minimum class weight and kart requirements after the heats and feature race or will be disqualified.

The driver should have the following safety equipment:   Snell 2010 24.1 or higher approved helmet ( DOT only is not legal), abrasion jacket, racing jacket or nomex suit, gloves, closed toed shoes, neck support or brace while on the track at all times.

Know all the flags of racing.  If you don’t understand them, ASK someone.

Racers are to line up on the starting grid in the order that is posted on the line up board at the score tower.

All kart stands must be put in the designated area & not left in the traffic areas.

If a kart is late or had mechanical difficulties on the grid, a maximum of 2 parade laps will be given .  If the kart cannot make it on the track during this time, they are ineligible to compete in that race.  No hot laps are permitted.

Any kart causing 3 intentional cautions in one race will be asked to leave the track surface for that race.

If the leader is taken out by a lapped kart, the leader may get his/her position back.  This is a race director call.

The flagman and/or race director have the right to single file the field if the race cannot be started after 2 attempts.  If the same driver(s) are causing the restarts, the flagman has the right to send the driver(s) to the rear.  All positions will be moved forward.

If there is an accident or debris on the track, a yellow (caution) flag will be displayed, all drivers must slow down to a pace speed.

Following a caution, all racers should line up in single file so the proper order can be confirmed by the scorekeeper.  The restart will be determined by the order of the last completed lap and the racer(s) who brought out the caution will restart in the rear of the field.

The lead kart is responsible for setting a reasonable pace for the rest of the field.  Restarts will be in single file IF deemed necessary by the officials.  Anyone caught jumping the start will be sent to the rear of the field.

Once a kart leaves the track and enters the “off ramp”/pit road/the infield they cannot return to that race.

Any racer who is considered by either the flagman or race director to be driving in an inappropriate unsafe manner, will be shown the black flag and must exit the track immediately for that race.   The driver will be given 0 points for that race.  If the racer is black flagged for equipment problems, the racer will be given last place points for that race.

Aggressive driving will not be tolerated.  Anyone who intentionally “takes out” any other racer will be sent to the rear of the field or be black flagged.  Disqualifications due to not making weight, being black flagged due to rough driving, intentionally rear ending other drivers during and/or at the end of the race or technical disqualifications will receive zero (0) points for that race.

In the event of an accident, we realize that family and friends are concerned, however, please do not enter the track until instructed to do so by the track officials.  This helps us to prevent other accidents from happening and getting the proper medical attention to the racers.  Only immediate family will be permitted on the track when the track official signals the “ALL CLEAR”.

If you have mechanical problems and can’t maintain a safe speed exit immediately to the pit area.  If you are unable to reach pit road, take your kart to the infield.  

After the heat & feature races all drivers are to report to the scale area.  After the feature the top 3 karts must report to the designated tech area immediately after being weighed at the scales.

General MCS Officials will use flags, as set forth in this section, for the purpose of providing drivers with information. MCS Officials may use light signals in addition to or in lieu of flag signals.

Green Flag (Start of Race) At the beginning of the race, when the starter gives the green flag, karts must maintain position as designated by MCS Officials until they have crossed the starting line. On restarts, all passing will be to the right until after passing the starting line.

Blue Flag with Diagonal Yellow Stripe (Passing Flag) The blue flag with a diagonal yellow stripe signifies that faster traffic is overtaking the karts being signaled. Karts being given this flag must prepare to yield to overtaking traffic and give 1 full lane to allow safe passage of karts racing for position.

Yellow Flag (Caution) A. The yellow flag signifies caution and this flag will be given by the flagman immediately following the occurrence of the cause for caution. When the yellow flag is displayed, all karts, regardless of their location on the track, will slow down and maintain position with respect to other karts. Restart order will be determined by the last green lap scored and karts causing caution incident will line up at the rear of the field. The MCS Officials have complete discretion to determine the positions of the karts at the time the yellow flag was displayed and to reposition the karts in accordance with their determination. B. Karts must slow down to a cautious pace on all yellow flags. C. In the event a caution kart is used, no kart may pass the caution kart unless directed to do so by an Official. Any karts illegally passing the caution kart will be penalized. D. The starter will signify one (1) lap before the green flag will again be displayed. E. Pit attendants and mechanics shall not go on the race track for any reason, while the karts are racing, or while they are running under the yellow flag. The only time drivers or karts may receive such services is when they are completely stopped and off and outside the race track. F. No pit crews may service or repair any wrecked or damaged kart until the kart has been removed from the racetrack and safely removed from race track.

Red Flag (Race Stop) A. The red flag means that the race must be stopped immediately regardless of the position of the karts on the track. The red flag shall be used if, in the opinion of MCS Officials, the track is unsafe to continue the race. Karts should be brought to a stop in an area designated by MCS Officials. No repairs or service of any nature will be permitted on any kart on the racetrack. B. Drivers are to stay in their karts at all times unless directed otherwise.

Black Flag (Leave Race Track Immediately) A. A black flag means to immediately exit race track and report to the MCS Official at the tech shed. It does not mean automatic disqualification. At the discretion of the MCS Officials, if the driver does not obey the black flag directive, the driver may then be given the black flag with a white cross to inform the driver that scoring of his or her kart has been discontinued until further notice. B. In lieu of a black flag, MCS Officials may use a blackboard or black flag number indicator in full view of the Competitor on which the number of the kart being black flagged.

White Flag (One lap to go) A. When the white flag is displayed, it means the leader has started his or her last lap. B. No kart may receive any assistance after the white flag has been displayed. Checkered Flag (End of Race) A. When a checkered flag is displayed it means the race is completed. When the lead kart has completed the required race distance, the race will be declared “official” regardless of flag being displayed. B. When the checkered flag is given to the leader, the balance of the field receives the checkered flag in the same lap. Finishing positions will be scored according to most laps traveled, whether the kart is still running or not. C. The driver receiving the checkered flag first in any feature race must bring his/her kart to the starting line or designated area and remain there until released by MCS Officials. Race Track Lights A. When the red light is displayed, it means all movement on the track is to cease. B. When the yellow light is displayed, it means caution is in effect.




The kart must start the feature event to receive points for that race.  The registered driver of the kart will earn points, no switching of drivers or switching of karts during the night of racing will be permitted, i.e.; the registered driver must race the heats and feature in the same kart, the driver cannot race a kart in the heat  and switch to another kart in the feature event.  Please discuss any concerns with the Race Director.


The break down for points are as follows:



10 points awarded per position for each kart in that class. (Example: 7 karts in the class 1st place will receive 70 points, 2nd place will receive 60 points, 3rd place will receive 50 points, 4th place will receive 40 points, etc.)

Same points rule applies to the 2nd heat race as the first.

Heat race points DO NOT count towards your points total. They are for the sole purpose of determining your starting position in the feature.

In case of a tie in points in the heat races to determine the starting positions for the feature race, the winner or higher point earner in the 1st heat race will be given the more forward starting position.



1st place-200 points plus the number of entries in the class. (Example: 200 points + 10 karts in class=210 points)

2nd place – 175 points plus the # of entries

3rd place – 155 points plus the # of entries

4th place – 140 points plus the # of entries

5th place – 130 points plus the # of entries

6th place – 120 points plus the # of entries

7th place – 110 points plus the # of entries

8th place – 100 points plus the # of entries

9th place –    90 points plus the # of entries

10th place –  80 points plus the # of entries

11th place – 75 points plus the # of entries

12th place – 70 points plus the # of entries

13th place –  65 points plus the # of entries

14th place – 60 points plus the # of entries

15th place – 55 points plus the # of entries]

And so forth


In the event of a tie for year end points, the championship will be broken by the number of feature wins for the season.  If there is still a tie, the winner will be determined by the last completed race finish of each competitor.
