*Clone and Predator divisions have multiple weights. The division you choose to run in is also how much you and your kart have to weigh together! 

** AGE WAIVER: An age waiver is a provision that allows a driver to compete in a class or classes they would not normally be eligible for due to age restrictions. The waiver enables the driver to "move up" to a higher class, provided the following conditions are met:

  • Parental Permission: The driver’s parent or legal guardian must give consent for the driver to move to a different class.
  • Approval from Track Officials: The track director and officials must approve the decision, ensuring that the move is in the best interest of safety and competition.
  • Proof of Ability: The driver must demonstrate that they are capable of competing at the higher level, often by showing sufficient skill, experience, and safety awareness.

This system allows younger drivers to participate in more competitive classes if they are ready, helping to facilitate their development and progression in the sport.

** Stock Predator was previously Stock Advance in the 24-25 Winter Season!

** Regular gas is defined as 87-octane. All karts that are required to run regular gas will be required to purchase fuel from Antioch Food Mart. We will be checking the top 5 karts to make sure they are running regular gas from Antioch Food Mart.

  11. Muffler: Stock OEM muffler in unaltered form must be used. If any doubts about the integrity of the muffler should arise, simply cut the muffler in two, to determine legality by comparing to known stock muffler.
  12. Governor: Governor gear, arm, and linkage must remain intact and functional. (As of MARCH 1st, 2024 competitors may utilize the DUCAR OEM rev limiting ignition coil (Part # 212-1260R) as an alternate to the stock OEM governor. You may remove the governor assembly completely and plug holes, leave governor in place and wire in the open position or leave the governor assembly in stock form. Regardless of method chosen, the engine still cannot free rev over 5500 rpm max). Track may require engine to be free revved on the stand to a certain RPM to determine if governor is properly functioning. (5500 rpm max for example) It has been our findings that some engines surge and some will not. We do not require the surge because in stock form the engine will perform best at 5000 rpm or less. However, this will be left entirely up to the race promoter/tech. We would like to make sure that all Tech Officials are aware that when using a rev limiting coil on any type of engine, the tachometer will show rpm spikes when the engine hits the limiter. As a result of this you will need to watch the tachometer if free revving the engine in post-race tech. The engine should rev to 5200-5300 rpm on average before showing spikes. You should NOT issue a DQ based on maximum recall due to the spikes shown by the rev limiting coil.
  13. Gas Tank: Stock tank should be removed and an auxiliary tank mounted in the floor pan should be used. A top plate and fuel pump are allowed with the pump be pulsed off the valve cover only. (Track Option) Utilize stock OEM tank with the vent tube unplugged and up to 4 - 1/8” holes in the fuel cap for venting.
  14. Low oil shutoff can be disconnected. No taping or decals added to the recoil in an attempt to block off air.
  15. Chain guard, throttle linkage, top plate and fuel pump are the only aftermarket parts allowed on the engine.
  16. There is no longer a claimer rule. The engine in question must be protested by a competitor or subject to tech by the track if the promoter/tech deems necessary. The protest and acceptance fees are to be determined by the track. Revised February 2024
  17. If there is any doubt as to the legality of any part on a Ducar 212 engine, the competitor has the right to file a protest with the track/official. The part in question can then be shipped to DynoCams for review. Please include contact information for the promoter and we will contact the promoter with our findings on the legality of the part in question in a timely manner.
