Each night your kart must go through a Pre-Race Tech check. The driver and kart must be brought to be checked with all of the drivers safety apparel as well. Young drivers must be accompanied by their crew chief. After the kart passes the Pre-Race Tech, the kart will receive a unique sticker for the night. If you place in the heats or feature, and don't have a Pre-Race Tech sticker, you will be disqualified.
Some of the items (but not all) will be listed below. The Pre-Race Tech director will be the final word on what will be allowed. Minor violations will be allowed for a 1 week period to allow time for it to get fixed. More serious issues will be required to be fixed before the kart can go on the track.
The following three areas must be safety wired or pinned:
Wolf plate - The wolf plate is a metal bracket that is mounted to the brake caliper and covers the area between the seat and the brake rotor. It's purpose is to protect the driver in the case of the seat falling back against the brake caliper and cutting through. A metal plate mounted on the back of the seat between the seat and brake disc is also allowed, but not recommended.
Engine - The 4 cycle engines are required to have a catch can to collect the oil blow by coming out of the breather tube. The exhaust header bolts must be safety wired and the exhaust muffler must be wired through the screen and then wired back to the engine to keep the muffler with the kart if it comes loose. The exhaust header or muffler must not extend beyond the rear of the back bumper.
Clutch - The 4 cycle class must run a chain guard on the engine. Also, the area between the seat and the engine must be protected so that the drivers arm cannot get down to the clutch or chain. A piece of heavy gauge plastic or similar piece of material riveted or bolted to the chain guard is an acceptable means of protection.
Wheels - The front wheel axle nut must be safety wired or pinned. The rear axle must have a snap ring or similar item at each end to keep the wheel from sliding off if it comes loose. DOUBLE CHECK the wheel nuts each time you go out on the track.
Fuel Tanks - On remotely mounted tanks, the tank must be mounted in the center of the kart underneath the steering column and between the drivers legs.
Before each heat - It is a good idea to inspect your kart for potential problems. Check the play in the spindle and front axle bearings. Inspect the front spindles, frame, bearing hangers, bumper, steering mounts and steering wheel for the signs of cracking. Double check that all bolts and mounting fasteners are tight. A little maintenance can be the difference between watching the race from the pits or the front of the pack.
This list is by no means complete and additional items may be added and checked when necessary. There may be something that was missed, and once again, the Pre-Race Tech Director will have the final say on all violations.
