WKA has added the Junior Intercontinental A (JICA) class to the 2006 Manufacturer’s Cup schedule. The class will run under the same rules as JICA in Stars of Karting. Here is the class description that will appear in the January Tech Updates.

 

Junior Intercontinental A

Due to the low level of participation, the EasyKart class has been eliminated from the 2006 Manufacturer’s Cup Series schedule. Competitors who wish to race their EasyKarts can continue to enter them in the TAG class.

In another effort to achieve TAG class parity among engines, the Sonik TX, Comer, and Italsistem ML47H engines will be required to run a longer connector pipe between the header and pipe. The minimum combined length of the header and connector pipe must be at least 17” as measured from the back side of the header flange at the cylinder, around the right side of the header, connector, and pipe to the first weld at the outer end of the divergent cone. See TM 58 Section 610.4.2 for more detailed information.

Here is a correction to the HPV cylinder specification as it is published in the 2006 WKA Technical Manual. Section 603.6 EXHAUST; INTAKE & TRANSFER PORTS states that, “There shall be no removal or addition of materials in the aluminum areas of the transfer passages.” The rule as published omitted the words, “or cast iron.” It should say, “There shall be no removal or addition of materials in the aluminum or cast iron areas of the transfer passages.” In other words, the transfer passages must remain as manufactured.

Finally, there are two new rules that apply to tires in the Manufacturer’s Cup Series. First, there is to be no use, possession, or sale of tire chemicals on race track premises. There are to be no exposed flames, tire boxes, tire rotisseries or tire cutting equipment on race track premises. In addition, air bleeders (tire relief valves or pop offs) are no longer legal.

Road Racing
The National Road Race Series committee developed a new, simpler and easier to enforce rule to define the laydown kart bodywork and included it in the 2006 WKA Technical Manual. Unfortunately, our creative competitors figured out a way around it before the ink was dry. The NRRS committee listened to the input of many of our competitors and developed the following revision. This is the revised rule that will appear in the January Tech Update and will be effective at Daytona.

308.3.3 COCKPIT OPENING: The kart must have an open cockpit from the front of the nose cone to the back of the headrest. The nose cone must have an opening above the driver's legs with a 6" minimum width and may cover foot area up to 3" rearward of both pedals in relaxed position. The nose cone must not interfere with driver's ability to operate pedals. From the back of the nose to the steering wheel there must be a minimum 12" opening in the bodywork. The cockpit opening shall be no less than 20" wide with a 10" maximum side panel width from the steering wheel to the front of the headrest (where back of helmet rests). Karts over 40” wide at the steering wheel are excluded from the 10” maximum side panel measurement. The 20” cockpit opening excludes the motor. There must be 6" clearance between the steering wheel and side panels with the wheels in a straight-ahead position. If used, the connector strip behind the headrest may not be made of metal

After due consideration, the NRRS committee has decided that TAG Enduro (Spec 125 Enduro) karts will not be allowed in the Formula 100 class. They will be legal in the Formula 125 class and will compete using B-Limited rules for weight, engine tech and fuel. TAG Enduro can also enter the Unlimited class. In either case, they will practice in Group 4.

At the NRRS event at Road Atlanta, it was discovered that many if not most of the bodywork on karts running in the WKA/ICC and CIK 125 Sprint Kart Classes was illegal. The distance between the front tire and the rear of the nose cone exceeded the 150 mm “C” dimension shown in the WKA Tech Manual. This was in spite of the fact that many of the karts were CIK approved, imported from Europe, and not modified in any way. As a result, WKA has decided to waived the “C” dimension until the CIK bodywork rules can be examined and the WKA rules reviewed and revised.

Also, remember the seat rule in the WKA/ICC and CIK 125 Sprint classes. Section 360.4.4 of the 2006 WKA Technical Manual describes the new CIK AND WKA/ICC 125 SPRINT SEAT and includes specific measurements. The NRRS committee developed this rule based on input from the drivers in these classes.

Due to late submission of the spec oils, the spec fuel and oil program will not be implemented at Daytona. The spec fuel and oil program will begin at the second race of the season at Kershaw. However, comprehensive fuel testing will be done in all appropriate classes at Daytona.
