  • Top 4 karts in each class enter post race tech. Check class weights in Section 2.
  • You may repair your team’s engine or kart only in your pit box/ area.
  • Engine will be off during driver change. (Anytime a butt is not fully in the seat the engine must be off).
  • All drivers must each be on track at least 45 minutes total.
  • No driver may drive for more than 130 minutes total time for any one team.
  • Fuel jugs will be standard, unmodified 2 – 5 gal container.  No NASCAR style “dump” cans or pressure type fuel jugs. See Tom Agan or Alan Freese if you have any question about your fuel jug.  Teams using a modified / non conforming fuel jug during the race will be penalized – see penalties section.
  • 2.37 gallon (9L) kart fuel tank max.     No chain oilers
  • All drivers must fit correctly in seat – tech inspector to verify.

 2. Syd White Enduro Class Weight Formula:

For qualifying, the kart and driver must meet minimum class weight

For the race, the formula below will be used:

(Average Driver Weight) + (Kart Weight) = Class weight

(driver x) + (driver y) + (driver z) / (total # of drivers) = Average driver weight


World Formula @ 365lbs = Team Munchkin

(Tony, 155 lbs) + (Jimmy, 175) + (Jeffery, 190)  = 520 lbs / 3 = 173.3 ADW

(173.3 ADW) + (Kart Weight) = 365lbs. (class weight) Kart Weight must = 191.7lbs.

Class weight (365) – Avg Driver Weight (173.3) = Minimum kart weigh (191.7)

For qualifying, kart and driver must meet minimum class weight.

Weight will be rounded to the nearest pound. Assuming a typical kart weight with engine of around 170 lbs this team would have to put on around 22 lbs. to make weight. I would also highly recommend accounting for some weight loss of team members during the race. Watch your fuel & weight at the end of the race - good luck!!

3.   Classes / Weights – Five Karts Make a Class

  • If you receive a black flag do not go to your pit!   Please complete the lap your on and drive directly to the Penalty box at the re- entry end of pit lane to serve your penalty. To clarify, you may not pit after you have been black-flagged- until you have served the penalty.  Failure to follow this rule will result in another black flag.  If you repeatedly fail to obey a black flag you will be dropped from scoring.
  • Meat ball flag – your kart has a mechanical problem – please exit track on next lap. Report to your pit – a pit steward will tell you what mechanical problem you have.
  • A single yellow flag means that there is a hazard ahead. Get your hand up; no passing and you need to slow down (for the safety of volunteer workers) until past the yellow flag area.
  • Red flag – Get your hand up!!! Do not pass!!! Please come to a slow, controlled stop, on track and stay in your kart. Please wait for directions.  No team members may go on track during a red flag.

8.   Notes:

  • If you would like a pre-race courtesy fuel check please see the tech director between 9:00am & 11:00am on Saturday.
  • Please clean up spills with quick dry or make sure the spill is on pig mat.
  • Be patient with your passes, damage to your kart will take time to fix.
  • You may have a crew member/driver start your kart during the LeMans start after driver is in kart seat.
  • You may replace a lost nose, rear bumper or side pods.
  • If your kart stops on track, please try to stop on the outside of the track. A team member will need to see the race director with a mobile kart stand. We may also choose to retrieve your kart & driver and deliver it to the scales area. 

This is not a normal race. An Enduro is much more complicated to run & race than a sprint race. Please be patient with volunteers, officials and your fellow racers as we are all here to have fun.
