3. Race Procedures

for the feature. In case of a tie for a position in the feature race, the driver
with the best finish in the first heat will get the advantage. Restarts after
the first lap will be single file.

6. Protest Procedure
Management reserves the right to protest any engine. To protest another driver’s
engine, take $50 to the tech person or other track official and show them the
engine you want to protest. This must be done no later than 15 minutes after the
end of the feature race for the engine being protested. Protestor must be in the
same feature race. The official will inform the driver that his/her engine has
been protested. At that time, they may accept the protest or forfeit their
finishing position. If accepted, the tech person will then take a methanol
sample from the engine and may test it with distilled water method. The driver
being protested will be informed by the official that he/she has 10 minutes to
remove the engine from the kart, drain the oil and fuel, and present the engine
tot the official for tech. The official will observe the process to make sure
that the engine is not tampered with during removal and draining. Any tampering
with the protested engine will make it illegal. The official will take the
engine to the tech room. There will be an appointed tech person and at least one
alternate. The protested driver may choose which one does the inspection. The
only persons allowed in the tech room during inspection are the engine owner,
the person who placed the protest, the chosen tech person, and the track owner.
If an illegal part is found at any point in the inspection, the inspection will
be stopped at that point and the engine will be declared illegal. If legal, $25
goes to the tech person and $25 to the engine owner. If illegal, $25 goes to the
tech person and $25 to the protestor. If an engine is found illegal, the racer
loses any money and points earned at that racing event. If the racer of an
illegal engine returns to another event, he/she must pay $25 to the track
management before he/she will be allowed to enter or participate in any race.
Management will return the $25 to the protestor.
