1 SAFETY AND COMPETITION RULES OF THE TEXAS SPRINT RACING SERIES, INC. FOR 2015 The Rules of the Texas Sprint Racing Series, Inc. (TSRS) follow. All participants in TSRS and all persons affiliated with them in any way, no matter how slight, shall be subject to these rules. By entering TSRS each participant and all those affiliated with them agree to be bound by these rules. 1. SAFETY DISCLAIMER 1.1. Kart racing has certain inherent risks. Each competitor assumes that risk when he/she participates in an event. While everyone involved, including officers, officials, and members of TSRS, drivers and crew members, can and have taken measures to reduce the risk of serious injury, the risk cannot be eliminated and, in fact, will always be present at a high level. Although safety is everyone s concern, The Texas Sprint Racing Series, Inc., its officers, officials and members cannot be, and are not, responsible for all or even most aspects of the safety effort. That responsibility rests with the various participants in the event(s) as follows: Competitors are closer to the racing facilities, track conditions, safety personnel and equipment, than are TSRS, its officers, officials and members, and are, therefore, better able to monitor track conditions on a continuing basis. Competitors are thus obligated to inspect, observe, and promptly report to the race officials any inadequacy in the facilities, personnel, equipment, or conditions at the track before, during, and after each event Competitors also are solely and directly responsible for the safety of their race karts and racing equipment and are obligated to perform their duties (whether as the vehicle owner, driver or crew member) in a manner designed to minimize to the degree possible, the risk of injury to themselves and others. Neither TSRS, its officers, officials nor members will be, or are responsible for the adequacy of a competitor s race kart, racing equipment, or racing activity to accomplish this purpose. 2. GENERAL RULES, PROCEDURES AND REGULATIONS 2.1. TSRS is NOT affiliated with, nor sanctioned by WKA, SKUSA, ProKart, Stars of Tomorrow, IKF or any other national karting organization. The TSRS Race Director may reference these sanctioning bodies rules to provide clarity to the TSRS rules and procedures. If there is any conflict in the TSRS rules, or if a question is not completely addressed, the Race Director and the Officers of TSRS present at the event will make such changes in the rules so that the conflict or dispute can be fairly settled. 3. RAIN OR ADVERSE CONDITIONS: 3.1. Wet weather racing rules will be in effect when the Race Director declares such conditions. Approved rain tires (not grooved race slicks) must be on track to enter the track Raceable wet conditions are defined as a wet track but without deep standing water or heavy running water on the track surface. Heavy rainfall or the presence of an electrical storm in an area is not acceptable wet weather racing conditions The Race Director has the authority to declare wet or dry at any time during the race day. A reasonable period of time will be allowed to change tires (not to exceed 20 minutes).. SAFETY AND COMPETITION RULES OF THE TEXAS SPRINT RACING SERIES, INC. FOR 2015 PAGE 1

5 5.23. GRID STEWARD: The Grid Steward shall be in charge of the grid area. When a driver's specific heat race is called, the steward will see that all karts are lined up in order. He will then call for a kart start-up. All drivers are solely responsible for having their karts on the starting grid TECH INSPECTOR: the Race Director shall appoint a Tech Inspector. All tech inspections performed by this Inspector shall be in accordance with the applicable TSRS competition regulations. The decision(s) of the Tech Inspector and the race officials shall be binding. If the Tech Inspector is unavailable, the President or Race Director may appoint one DRIVER S MEETINGS: All drivers must attend the driver s meetings for the race at a location designated by TSRS. Failure to attend such meeting shall result from disqualification from TSRS with no refund or further recourse of any kind All weights must be pointed white and either safety wired or double nutted Cameras are allowed but must be mounted on the kart not on the driver. No helmet cams are allowed. 6. FLAGS SECTION: 6.1. GREEN FLAG: Displayed at the start of the race or practice session, and kept visible as long as the track is clear for racing. Racing begins when the green flag is shown by the flagman YELLOW FLAG: A yellow flag shown anywhere on the track is for that area only. No passing is allowed. It is the racer s responsibility to control his/her kart and avoid other karts and track workers involved in any mishaps. Anyone violating this rule may be penalized at the Race Director s discretion. A yellow flag displayed by the Starter signifies the complete racecourse is under a yellow flag condition; no passing, slow down, be prepared to stop, do not resume racing until the Starter displays a green flag. Any one violating this rule will be penalized RED FLAG: The red flag shall be displayed when, in the opinion of the race director or starter, an unsafe condition exists on the track. (An injured driver necessitating medical attention shall automatically require a red flag.) The red flag shall only be displayed by the starter or race director. When the red flag is shown all corner workers will display their yellow flags, all drivers must slow their karts immediately, with caution and if the track is clear slowly proceed to the top of turn two and turn off their engine(s). NO WORK IS PERMITTED ON THE KARTS. If a red flag is thrown before all karts running have gone through scoring once, then a restart shall be required, using the original grid line up. If all karts running have gone through scoring at least once, the last completed lap scored shall be the line up for the restart. This restart shall be in single file. (Karts shall have 90 seconds to start.) The official scoring sheet shall determine the lineup. All karts involved in any incident will be safety checked by the tech committee or their designee before being allowed back on the track. Notwithstanding the above paragraph, the following conditions will cause a kart to be penalized on the restart line up. a) Karts causing or involved in an accident, as determined by the race director or race officials, during or subsequent to the last officially scored lap shall be put to the rear of the pack. The decision of the race director or race officials as to whether a kart caused the incident is not protestable. b) The race director may, prior to the restart, black flag a participant who will be subject to condition of the black flag. c) If the red flag has been displayed, necessitating a restart, a kart previously dropped out prior to the red flag cannot restart the race. In the event that a heat is red flagged, it may be called complete if 50% of the laps are completed. The finish order shall be as of the last completed lap SAFETY AND COMPETITION RULES OF THE TEXAS SPRINT RACING SERIES, INC. FOR 2015 PAGE 5

6 scored subject to paragraphs 1, 2 and 3 above. If the red flag is displayed during the last lap of the race, the race will be terminated with the finish order based on the last completed lap scored. A kart or karts that necessitated a red flag on the last official lap may, based on the race director or race official decision, be disqualified and receive no points or last place points of the karts running, for that heat or race. ANY TIME THE RED FLAG IS SHOWN, THE TRACK IS CLOSED AND NO ONE IS ALLOWED ON THE TRACK YELLOW & RED FLAGS WAVED: Restart, reform pack for restart at a slow pace (in grid position) BLACK FLAG: When an unrolled black flag is displayed to a kart, the kart/driver is required to go immediately to the tech area. In addition to the unrolled black flag, the kart s number may be displayed on the flag stand number board. Anyone violating this rule may be penalized or suspended ROLLED BLACK FLAG: A rolled black flag warns a driver that his/her driving borders on disqualification, the driver is being closely watched by all track workers, and subsequent possible violations may result in a unrolled black flag. In addition to the rolled black flag, the kart s number may be displayed on the flag stand number board BLUE FLAG: A blue flag is shown to a kart or karts being lapped by faster traffic. When a kart is being lapped they will hold their line and give right of way to the faster traffic and will point (if possible) to the side of the kart they want the faster traffic to pass on. At no time do they race with the faster traffic CROSSED GREEN AND WHITE FLAGS: One half of the race is completed WHITE FLAG: One lap to go CHECKERED FLAG: You have finished the race or practice session. Reduce speed and return to the pits CROSSED YELLOW AND GREEN FLAGS: The starter shall signify a pace lap or lineup command with a crossed yellow and green flag. During the running of an event or heat race, the Race Director or Flagman may use both the Checkered flag and the Black flag combined to finish the event or heat if suspicious or reports of foul, rough or illegal driving or unsportsmanlike conduct are present. It shall then be considered that the Race Director or Flagman finished the event or heat race under official protest. 7. COMPETITION SECTION: 7.1. NO RELIEF OR SUBSTITUTE DRIVERS will be allowed. The driver of record (one who is registered) must qualify or declare the entry and must drive any/or all heats for that race day RADIOS PROHIBITED: Voice communication of any type (radio, headset, etc) with the driver while he/she is on track is illegal TRIPODS for all competitor s timing, computer systems, etc. on race day the transponder will be located on the left side of the track at the start finish line THE OILING of chains or clutches on the track is prohibited. NO ANTIFREEZE is allowed in karts.

All classes must be chosen during SAFETY AND COMPETITION RULES OF THE TEXAS SPRINT RACING SERIES, INC. FOR 2015 PAGE 6

7 registration and may not be changed once the first class qualifies, or kid karts have their first event. If change is made later, the driver will start at the back of the class for the first two heats ON THE GRID: All drivers are solely responsible for having their karts on the starting grid. All karts, in qualification, pre-final, or final, must be on the starting Grid within THREE (3) minutes of the start of the heat/event SCRATCH: Drivers shall notify the Grid Steward if he or she is unable to make the next heat or heats IN THE EVENT A KART OR KARTS FAIL TO MAKE THE GRID, the remaining karts on the grid will move up to fill the vacancy/vacancies using the criss-cross method. Any kart not on the grid at the time the grid is released still has ninety (90) seconds (duals have 180 seconds) to enter the track and start at the back of the class. Vacancies in the lineup, occurring while on the track during the pace laps, shall be filled by the kart or karts moving straight forward to fill the vacancy or vacancies, except shifters leave a space on starting grid vacant SECOND RULE: After the karts leave the starting grid, if one or more karts are still on the grid, those karts have ninety (90) seconds to enter the track and assume their original starting positions RESTARTS: Restarts for all classes - if the kart is able to restart with an onboard starter they can restart during the warm-up lap. Classes that have karts with on board starters may also restart after the green flag has been displayed if the driver is able to restart without exiting the kart. Drivers are not allowed to restart after exiting their kart. In either case they must do so in a safe manner or will be black flagged for doing so. Karts reentering the track must yield to on track karts and should not cause on track karts to have to change their line. For safety reasons, no persons are allowed on the track or infield when karts are on the track. If a kart dies on the track or is having trouble, the driver may not restart the kart unless it has an onboard starter. No push backs are allowed after the kart has cleared the entrance ramp to the track, or the designated push back area on race day FIRST TURN RESTARTS: If fifty percent (50%) or more of the karts do not successfully negotiate the first turn, the race will be restarted SPORTSMANLIKE DRIVING: The spirit and intent of sportsmanlike racing competition is to proceed on the track without touching or endangering the vehicles of fellow participants. Inadvertent contact is a reality of racing; however, if in the judgment of the presiding officials, a participant is bumping, crowding, chopping, blocking, pushing, or driving in an over aggressive / negligent / reckless manner, that participant shall be subject to immediate disqualification from the event PROHIBITED WARMING OF TIRES: It is illegal to warm or heat tires, in any manner, in the pits, pre-grid, and on the track at any event. This includes raising the rear of the kart off the ground and the driver accelerating then lowering the kart to touch the ground while on the grid DRIVING OFF TRACK: Any driver leaving the course or cutting the apex of the corner, attempting to pass another competitor, is subject to disqualification. Any driver who goes off track will yield to karts already on the track, waiting until a safe opening allows for re-entry onto the track. At no time will the competitor who goes off track race karts that are still on the track. Doing so may result in disqualification for the event NUMBER PANELS: Kart numbers must be displayed on all four sides of the kart. Numbers must be no more than 3 digits long. Number should not be obstructed by bumpers, SAFETY AND COMPETITION RULES OF THE TEXAS SPRINT RACING SERIES, INC. FOR 2015 PAGE 7

8 pipes, or other obstructions and must be easily readable by track personnel. It is suggested that you use black numbers on white panels or white numbers on black panels POST-RACE TECH: Each category class must be teched at least once prior to entry onto the track. Any competitor in any class finishing in the top five places must go through the tech process immediately after taking the checkered flag. Refusal to submit to tech inspection will result in disqualification. It shall be the competitor's prerogative to file a protest after the tech inspectors have made a decision. The protest will be decided by three officers of TSRS. The drivers should have a small set of tools, such as, screw drivers, wire cutters, and wrenches with them in order to remove items for tech inspection. At the end of a competition, all karts and drivers shall proceed directly to the scales for weight inspection. Only the drivers for the current class being weighed shall be allowed in the scale area. Drivers shall be weighed in full driving uniform, including helmet, jacket, shoes or boots, etc., after qualifying, each heat, and main event. Drivers shall not add any weight to themselves or their karts between the finish of the competition and weigh-in of driver and kart. Any driver found adding weight between the finish and weigh-in shall be disqualified from the event. Any driver leaving the scale area without weighing in shall be disqualified from that portion of the event. Any competitor that fails to meet minimum weight for his class shall be disqualified from that portion of the event. Any driver that fails to meet the minimum weight for his class shall have the opportunity to re-weigh, once only. The driver and his kart shall be removed from the scale, the scale shall be readjusted to original settings (zeroed for electronic scales) and the driver and kart re-weighed. Failure to meet weight at this re-weigh shall result in disqualification from that portion of the event. The race officials always have the right to alter standard procedures to repair or adjust a malfunctioning scale. All competitors shall proceed from the scale to the impound area unless released by a Race Official. Each of the drivers selected for post tech inspection will be checked for: Weight, Fuel, Exhaust / Carburetor (Restrictor/Venturi Size) and/or Technical Inspection Pill Draw. One representative per engine is allowed (required) in this area for the purpose of observation, as well as assisting in the tear down procedure under the direction of the tech official. Discussions of all tech personnel involved in deciding compliance of equipment shall be confined to this area and limited to other assigned inspectors RESTRICTORS MAY BE CHECKED every race day for any or all finishers of all restricted classes, with engines painted after the first heat WEIGHT TECH: Drivers and karts with weight requirements must weigh after each heat at the Race Director's discretion VISUAL MODIFICATIONS-STOCK CLASSES: The track officers have the right to disqualify any visual modification of any stock class engine until the discrepancy is corrected ENGINE TECH: The Tech Inspector may examine any stock engine. This is a teardown inspection for proof of non-modification. Any non-major tech item may be teched at any time during the race event at the Race Directors discretion; refusal to be teched is immediate disqualification. Disciplinary action follows section rules for disciplinary action FUEL TECH: Fuel may be teched in stock classes at any time, and it should pass the Digitron meter as specified (changed to -75 to accommodate reformulated fuel). 8. REAR BUMPER RULE: 8.1 Full width rigid rear bumpers are required on all karts. Metal or plastic rigid rear bumpers that are approved by current IKF or WKA regulations are approved for TSRS.

20 2015 Local Option/Junior206 Engine United States Class Regulations The 206 engine platform was designed and engineered exclusively for racing. Each engine is hand-built in Milwaukee, Wisconsin using dedicated tooling and dies to provide a level of consistency unmatched in the industry today. The 206 is intended to simplify racing, from hitting the track to the tech process needed to ensure a level playing field at the end of the day. In combination with Briggs & Stratton Racing s slide restriction system a complete racing ladder can be developed by simply changing a carburetor slide and/or by a slide and ignition change. With the base engine the basis for today s box stock classifications, the 206 engine gives racer s and tracks the ability to have one engine, from start to finish. All Briggs & Stratton (B&S) racing engines are manufactured solely for sanctioned racing only. B&S does not recommend the products referenced herein to be used for an application outside of sanctioned racing as serious injury or death could result. This rule package has been prepared by Briggs & Stratton Racing and is intended to establish the basis for the technical control of the classes in which the 206 and 206 contact your sanctioning body. 1.
