NTK 2012 Rulebook Changes

Here are some of the major changes in the NTK 2012 rulebook that will take effect on March 1st, 2012.

We are now using the IKF rulebook. The NTK rulebook will supersede the IKF rulebook. We have IKF rulebooks on sale for $15.00.

Starting March 1st, all karts must be equipped with a rear bumper to protect the driver and kart from rear impact and to keep a following kart from reaching the rear tires. The bumper may be either CIK style plastic “rear wheel protection” or steel tube of a double bar design. Welded on “elephant ear” extensions are permissible. The bumper shall extent to at least the center of the rear tires.

Kart weights must be painted white and have a nut and be drilled and safety wired.

The mounting position for the scoring transponder shall be placed a minimum of 12 inches rearward of the centerline of the top left king pin to the leading edge of the transponder. If it’s on the seat it’s OK. If you are running a Rotax kart, it will be per Rotax rules, and the transponder will need to be mounted on the seat. IKF rule 206.2

Rookie Drivers: FIRST TIME DRIVERS: All drivers racing or practicing at North Texas Kartway for the first time must display an orange number plate on the back of his/her kart and race at the back of the class for three (3) races. He/she must have their Rookie Card signed by three race directors or NTK elected officials.

The biggest change will be to the names of the classes. They are as follows:

2.1 CLASS STRUCTURE:

NTK Senior Structured classes with engines and weights: Engine tech will be per IKF tech manual unless specified herein. See IKF manual for additional classes, rule 207 and 850.

2.1.5 KID KART: Ages 5 thru 7 years. Comer C-50 or C51 engines allowed. Chain guard to completely cover chain when viewed from above. Chain/Gearing: 219 chain, 10 tooth driver, 89-tooth axle sprocket. No “offset” karts. Wheelbase: minimum 29”, maximum 31” Width: Front, max. 40”, as measured to outside of rim/tire (no minimum). Rear minimum 39”, maximum 42”, as measured to outside of rim/tire. Rear bumper: Continuous loop shape with vertical or angled bracing connecting upper and lower loop rails. Must protect rear tires. Seat may not be offset beyond outside edge of left frame rail. Steering height, maximum 20”. Seat height minimum 12” Side pods or double nerf bars and nose cones are mandatory.

NTK safety tech procedures and regulations apply. Weight: 150 lbs. minimum. Kid Kart Grids – 1st heat random, 2nd heat inverted, 3rd heat accumulated points from first two heats. Kid Karts will line up on the track as the shifter karts do (parents allowed on the track for the start and then must man a corner). Kid Kart is non-competitive class. All participants will receive first place points. Engine Tech per IKF tech.

We are implementing the following regulations for the grid and pit areas.

1) The practice of running engines at high rpm's for extended periods will no longer be allowed in pits, pre-grid or grid areas.
2) When in the pre-grid area no running is allowed
3) When in grid area the engines may only be run on the ground not on stands.
4) At events where fuel is supplied will be allowed a minimum amount of low RPM running to ensure the fuel has reached the carburetor. This will only be allowed when under the direct supervision of a designated race official.

We realize that it is frequently necessary to run the engine after maintenance, this will only be permitted at modest RPM levels for limited periods of time. Extended running at RPMs above clutch stall speeds to preheat motors prior to racing is no longer permitted.
