Speedway alone reserves the right to exchange a house prepared Engine that has been verified and is in good running order, for any Engine on any specific kart or karts; for any reason, at any time during the race/event.

All items under the seal will be exchanged. This will be a permanent exchange. The selected Engine will be surrendered immediately upon request by Speedway. The house prepared Engine will then be marked and released by the Tech Official to be installed on the kart. The kart must continue the race night/event with that Engine only. The selected kart owner/driver will have five minutes from the time he or she receives the request to surrender the engine to comply or be disqualified.

No engine exchange of any other kind will be permitted. The exchanged engine will be inspected and upon approval will be placed back in circulation on the next exchange. Speedway reserves the right to make any variance to this rule.
