Friday NIGHT racing at the HMB Hanging Rock Kartway (September 9th)

Due to the forecast for Saturday (over 80% and 2 inches of rain), we will race Friday night. It appears the Southeast will be flooded Saturday and Sunday. Below you will find the classes we are running. If the weather changes for Saturday, we will race then as well. Gate prices, parking prices and entry fees have been adjusted. See below.



To clarify, WE WILL RACE FRIDAY NIGHT. If Saturday becomes an option, we will run then too.



All reserved parking will open back up. If you already have parking, you have first dibs. But YOU MUST message us on our Facebook page to keep it. If you don’t let us know, by tonight, we will assume you are not coming. Parking has been reduced for the Friday night show. If we can run Saturday, you will have the options to purchase parking at the same rate as Friday’s show.

Reserve Parking is as following:
Class Sponsorship spots (40-54) $50
Front row (1-39) (55-65) $25
All other parking is free

  • 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.
  • Governor: Governor gear, arm and linkage must remain intact and functional. 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.
  • 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. The vent tube can be unplugged and up to 4 - 1/8” holes in the fuel cap for venting.
  • Low oil shutoff can be disconnected. No taping or decals added to the recoil in an attempt to block off air.
  • Chain guard, throttle linkage, top plate and fuel pump are the only aftermarket parts allowed on the engine.
  • 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 promotor/tech deems necessary. The protest fee will be $150 and acceptance fee will be $50. If the protested engine is found to
    be illegal, the protested driver will forfeit the $50.
  • 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 promotor and we will contact the promotor with our findings on the legality of the part in question in a timely manner.
