  1. The engine seal number (received in Registration) shall be entered by each driver on the Pre-Tech Certification form that is turned in prior to the first competition session (i.e., qualifying), and installed on the kart as instructed. This seal must remain in place for the duration of the event. See the event Technical Director for additional assistance.
  2. Engines and/or components may also be "painted" by the event technical staff at the post qualifying weigh-in.
  3. Event technical staff may inspect an engine's seal number and/or "paint" at any time during the event.
  4. Any engine change subsequent to qualifying MUST be pre-approved by the event Tech Director and if not, will result in a DQ and loss of points for ALL prior race sessions and a last place start in the next race session.
  5. It is solely the driver's responsibility to solicit and receive an engine change approval form from and executed by the event Tech Director. It is also the driver’s responsibility to demonstrate engine damage in order to get Tech Director approval to change engines. If the competitor is unable to demonstrate damage, one additional engine (total of 2) may be approved by the event Technical Director. If approved, the competitor will start the next competition session at the back of the lineup.

Chassis Seals

All chassis must be sealed for competition by qualifying on the first day of competition. Chassis seals will be available with your entry and can be picked up in registration.


PKC employs a self-certification form to facilitate pre-tech inspection, and this form will be provided at Registration. The driver completes and signs the form to certify that the listed items are in compliance. The form is then submitted on the grid for qualifying. Drivers are not allowed out for qualifying without turning in an executed pre-tech form. Spot checks of safety items will be made throughout the event and violations may result in penalty assessments. Check the event information to download latest version.
