Ok here it all is there's a lot of info here i sugest you print it out
Here is the scoop on the Goldendale, Washington desert race. It will be held at the Starvation ridge motorcycle G.P. track. JUNE 12 -14 2009 (go to www.overthebarsgang.com for directions to the track) The race course is on private land, no BLM. This is a desert style race on a 10.2 mile loop, the most laps in 4 hours wins. We are going to try 30 second start intervals; this will depend on car count. Faster class Vehicles will leave the starting line first. There will be hot pits just off of the course, for fuel, tires, and small repairs. Each team must have fire extinguisher present during refueling. Major repairs will have to go to main pits. Hot pit top speed will be 15 MPH and 5 MPH for the main pit (SPEED WILL BE ENFORCED) this is for spectator safety! Each lap you will stop at START/FINSH line to be electronically scored, lap time will be displayed on reader board (no transponders). Entry fees – Everyone pays $10.00 gate fee. Trucks and Buggies entry fee $200. Pays back one spot for every 3 entered in that class. UTV and (Samurai = Zuki world challenge) $100 Entry fee. Pays back one spot for every 3 entered.
Trucks will have 3 classes, Pre-runner, Sportsman, and Pro Truck classes. Buggies will have 3 classes, 1600, Sportsman buggy and Pro buggy. UTV will have 2 classes, STOCK and Modified. Samurai class’s is called Zuki world challenge.
Truck and Buggy class rules will be relaxed due to wide diversity of race vehicles.
Zuki world challenge vehicles will have own class rules. Safety rules will be followed and tech inspector will have final say on safety and class assignment. Noise restrictions are enforced, Please don’t come out with a loud vehicle, Motorcycles when racing here have to meet noise level and so do we! Course will be open for pre-run Saturday morning, 9:00 am- 1:00 pm. 25 MPH max for pre-run. UTV and Zuki world challenge classes will race together for 4 hours Saturday after noon, 2:00 P.M. to 6:00 P.M. Contact Eric Bewley @ 541-967-3255 for more info on the Zuki world challenge class. Sunday morning ALL buggy classes run 8:00 A.M. to 12:00 A.M. Sunday afternoon ALL truck classes will run from 1:00 P.M. to 5:00 P.M. pay out following scoring of truck race.
Gates open Friday the 12th $10.00 gate fee, overnight camping allowed, (no camp fires due to county restrictions and tall dry grass and winds) Concession stand will be present, trying to get a couple vendors to appear with displays for parts and safety equipment. Mid Valley Crawler 4X4 club will give assistance for on course race vehicle recovery. Track is accessible at race mile 5 by county road. We are going to try and have a 2nd pit at that location. (NO CHASE OR TEAM VEHICLE ON RACE COURSE DURING COMPITTION, ONLY AUTHORIZED RECOVERY VEHICLES)
The track has wide sections for 3- wide and narrow one lane sections. (See pictures) I have pre-run the course with a stock suspension Explorer on 31” all-terrain tires. Mud or all-terrain street tires will work fine on this race course. The race course is all dirt, no silt beds, no real rocky sections, a few jumps to get some air.
As for communications, we had cell phone coverage most the way around the course.
PASSING AND NERFING- this is a desert race. Mirrors and horns mandatory!! It is the driver / co-driver responsibility to check the mirrors for faster approaching vehicles. A race car in the mirror and blowing horn means the car behind you is faster has caught up to you, and wants to pass. Move to the side of the course or pull over to allow the faster car by. (Veteran racers please be patient with new racers) If you hold up a faster car or don’t acknowledge or signal to them, you will get a bump on the rear bumper. If you still don’t let them by, they will nerf you. This is not a short course race or big money race, so please respect the other racers both passing and being passed. We are here to have fun desert racing close to home here in the Northwest. This could turn into something bigger and better down the road. It depends on us as racers to make this as safe and fun as possible.
Go to www.nwprerunners.com for posted safety rules, class rules, and entry fees. The www.nwprerunners.com website will be the main website for info regarding this race, Please post on other sites about this race to get the word out! Print out the race info and pass them out. Review the SAFETY RULES and Class rules to see what class you feel you should be in. Post on the nwprerunners site any questions so all can see, someone else may have the same questions.

DEFINITION
Open cockpit is a vehicle whose rollcage is open to the outside and the main structure of the passenger compartment with body panels attached to it.
Closed cockpit is a vehicle that has a manufacturer's stock steel passenger compartment with a rollcage installed in the interior of the passenger compartment.
MATERIAL
Rollcage construction material may be crew, dom, whr, wcr mild carbon steel or 4130 chromoly. 4130 chromoly is highly recommended for all rollcage construction. Stress relieve all welded intersections by flame annealing. All welds must be of high quality and craftsmanship with good penetration and with no undercutting of parent material. Oxy-acetylene brazing on rollcage is strictly forbidden.
ROLLCAGE DESIGN
All rollcages must be designed and constructed with one front vertical hoop, one rear vertical hoop, two interconnecting top bars, two rear down braces, one diagonal brace and all necessary gussets. The two top interconnecting bars must be placed as far to the outside of the top part of the front and rear hoops as possible. Rear down braces and diagonal brace must angle a minimum of 30 degrees from vertical. Opened-wheeled vehicles built only wide enough for a single seat are excluded from having the diagonal brace (although the diagonal brace is highly recommended for the single seat vehicles). At the bottom of the diagonal brace there must be a cross member of the same tubing material and dimensions as the hoop. All rollcage components (hoops, braces, gussets, etc.) must have a minimum of 3-inch clearance from the component to the vehicle occupant’s helmets when occupants are seated in their normal riding positions. All portions of the roll bar or bracing that might come into contact with the vehicle occupant’s helmets must be padded. All portions of the roll bar or bracing that might come into contact with the vehicle occupant’s helmets must be padded.
Rollcages must be securely mounted to the frame or body. All intersecting points must be gusseted and braced. Cab or body mounted rollcages must be bolted through the body structure and be attached by use of a minimum two 0.1875-inch thick doubler plates (one on each side of body structure). Bolts and nuts must be at least 0.375-inch-diameter s.a.e. Grade 8 or equivalent aircraft quality. Welding of cab or body mounted rollcages to body structure is strictly prohibited. Rollcage terminal ends must be attached to a frame or body member that will support maximum impact and not shear or allow more than 1.5 inches of movement in the cage terminal end.
.
Gussets constructed of 0.125-inch x 3-inch x 3-inch flat-plate or split, formed and welded corner-tubing, or tubing-gussets made of the same material and thickness as the rollcage may be used. Gussets must be installed at all major intersections, including diagonal and rear down braces, where single weld fractures can affect occupants’ safety.
.
SAFETY HARNESS
All vehicles must have a heavy-duty type five-point fast release latch (no push button type) seat belt, anti-submarine strap and shoulder straps with metal-to-metal buckles and connectors for each occupant. The five-point harness system shall consist of one 2-inch wide anti-submarine strap, one 3-inch wide seat belt and two 3-inch wide shoulder straps (no “y” type shoulder belts permitted). Chest buckles are optional. Harness material shall be made of nylon or Dacron polyester. Harness must be in new or perfect condition with no cuts, frayed layers, chemical stains, or excessive dirt and must be in flexible condition (i.e. material must not be rigid). All harnesses must show the manufacturer’s name and the month and year of manufacture. No portion of the harness may be altered in any fashion from the manufacturer’s standard design. No surplus safety harnesses are permitted. Where “D” rings are used they must be doubled up, for example, two “D” rings per shoulder strap. Bolted mounting tabs are not considered to be “D” rings. A single “D” ring may be utilized if the loose end is sewn to the main portion of the shoulder strap in an “X” and “BOX” pattern and meets with K.O.R.R.B.C. approval.
The five-point harness must be mounted to the main structure members of the same size and dimension as the roll cage and be gusseted. The structure members must be in the following locations. Anti-submarine belt to the floor structure as close to the front of the seat as practical in order to exert maximum restraint to the upward movement of the seat belt and shoulder straps. Shoulder straps must be mounted behind the occupants seats and be located a minimum of 4 inches below the top of the occupants shoulders. Seat belt should be mounted a minimum of 2.5 inches forward of the intersection of the back of the seat and the sitting portion of the seat. All adjustment buckles must be a minimum distance of 1.5 inches from the seat to prevent loosening or chafing.
Mounting hardware must be a minimum of 0.312-inch hardened steel bolts with a 1.5-inch diameter flat washer attached through the body or frame using lock nuts or cotter keys. All harness hardware must be safety tied. If a wrap around type harnesses is used, care must be taken to prevent them from slipping and chafing from sharp frame components. Wraparound harnesses are highly discouraged.
SAFETY NETS
K.O.R.R.B.C. approved safety nets are mandatory on all vehicles and must cover the complete open area of the cockpit on both sides of the vehicle. Nets must be installed on the inside of the roll cage to prevent them from being damaged or coming off in the event of a roll over or slide on the side. Nets attached to doorframes are permitted as long as door has a positive secondary latching device. Nets must be installed so that the occupants can release the netting unassisted and exit the vehicle regardless of the position of the vehicle. Net installation must meet with the approval of the chief technical inspector. Lexan in the side windows can be substituted for nets as long as positive secondary latching devices are used. Lexan side windows must be mounted in such a fashion as to allow quick removal in event door will not open.
The net border or edge and the net attachment must be made of materials that are as strong or stronger than the net itself. Net attachments must be every 6 inches. Acceptable attachments are not limited to the following: hose clamps, snaps, heavy-duty nylon ties, lift-a-dot, metal hooks and steel rods. Steel rods are acceptable methods of bottom fastening.
The roof must be covered with sheet metal or aluminum.
K.O.R.R.B.C. requires that occupants of all vehicles must be protected during a roll over in such a manner that prevents them from extending from the body or frame of vehicle.
SEATING
A recognized manufacturer that specializes in seats for racing applications must make all seats. No stock production seats are allowed. All seats must be securely mounted to frame of vehicle and be properly reinforced in such a manner as to keep seat from moving in relationship to the frame. Adjustable track type seats must be securely mounted as to allow no lateral or vertical movement. Stock VW-type seat runners must be clamped to the floor with a minimum of two 0.375-inch diameter U-bolts per rail and have 1-inch minimum diameter flat washers on the underside. Head and neck restraints designed and installed to prevent whiplash are mandatory on all vehicles. Restraints must be a headrest constructed of at least 2-inch thick resilient padding and be approximately 36 square inches in area. All portions of the roll bar or bracing that might come into contact with the vehicle occupant’s helmets must be padded.
GENERAL VEHICLE COMPONENTS
DRIVER’S COMPARTMENT
The vehicle occupants must be able to enter and exit, unassisted and with great ease, the driving compartment with the vehicle in any position. Firewalls and/or bulkheads must separate the driving compartment from any fuels, engine fluids and acids.
FIREWALLS
All vehicles must have an all-metal firewall separating the driver’s compartment from the danger of fire from the engine and fuel supplies. A minimum firewall must be liquid tight and extend from the driver’s shoulder height to the vehicle floor and from body side to body side. If rear mounted fuel cell is higher than drivers shoulder height, the firewall must extend at least 2 inches above the top of the fuel cell. The hood is considered an extension of the firewall on front engine vehicles.
Any hole placed in the firewall for structure members, lines, etc. must be kept to a minimum. The hole should not have more than 0.0625-inch gap around the items passing through the firewall. Metallic tape must be used to seal the hole between the firewall and the item passing through the firewall.
FLOORBOARDS
Floorboards or belly pans are required on all vehicles and must be attached by a minimum of six 0.25-inch bolts (Dzus fasteners are not permitted) per side if not an integral part of the body or chassis. Floorboards must cover the entire area from in front of the pedal assembly to behind the seats and from outside edge to outside edge on each side. Floorboards in the front must extend up in front of the pedal assembly. Installation must be done in such a manner as to afford maximum protection to the occupants from debris.
BUMPERS
No hazardous front or rear bumpers, nerf bars, frame heads or other protruding objects from vehicles are permitted. Ends must be capped and rounded to prevent any sharp edges. Bumpers and nerf bars must be designed in a way as to reasonably inhibit two vehicles from becoming locked together. A safe front and rear bumper is required on all vehicles. Design of front and rear bumpers may be specified in some restricted classes.
SKID PLATES
Skid plates designed to reasonably protect the front suspension, steering and brake components are recommended on all vehicles. Skid plate must be made of metal and be securely attached.
Hoses
All fuel and brake line hoses including metal lines and fittings must be clamped and/or safety wired.
IDENTIFICATION MARKERS
All vehicles in competition must display the official K.O.R.R.B.C. decal on both sides of the vehicle. All vehicles in competition must be identified with the correct class vehicle numbers and be displayed in the proper locations as prescribed herein.
All pro-class entries must have black numbers on white backgrounds. If vehicle is white then the number area must be outlined in a ¾” black line around the numbers. There must be a gap of at least 1 ¼” between the black line and the numbers. Any number location that is deemed by K.O.R.R.B.C. to be too hard to read will have to be changed prior to vehicle competing in the event.
All sportsman-class vehicles will have black numbers on a yellow background. If vehicle is yellow then the number area must be outlined in a ¾” black line around the numbers. There must be a gap of at least 1 ¼” between the black line and the numbers. This is mandatory. No other combination will be permitted.
Note: K.O.R.R.B.C. assumes no responsibility for scoring vehicles with unrecognizable numbers. It is the vehicle driver’s responsibility for keeping numbers recognizable.
All vehicles in competition must have identification numbers in the following locations and sizes:
• Minimum 10 inches high with 1-inch-wide stroke on each side of vehicle inline with the occupants.
• Minimum 6 inches high with 1-inch-wide stroke on the rear of vehicle and is plainly visible from the rear.
• Minimum 4 inches high located on the front of vehicle and is plainly visible from the front of the vehicle.
ADVERTISING ON VEHICLES
Advertising, symbols and names may be displayed on vehicles contingent that they do not interfere with identification markings and provided that they are in good taste.
WORKMANSHIP
All construction, modifications and alterations must be performed in a workmanlike manner and meet with the rules, regulations and approval of K.O.R.R.B.C..
