RULES CORRECTIONS & CLARIFICATIONS - EFFECTIVE IMMEDIATELY

Revisions to Section 200 of the WKA Tech Manual have created a slight difference in a few areas with our US Chassis Manufacturers. To better accommodate both the American Specs and the CIK specs, the following revisions have been implemented.

Revisions and Clarifications 12.2.03

Figure 209, page TM 13 should be changed from "Attachments parallel to ground and perpendicular to axis" to "attachments should be horizontal and attach to main frame / front axle as shown in Diagram 209."

Figure 209, page TM 13 should be changed from "Attachments parallel to ground and perpendicular to axis" to "attachments should be horizontal and attach to main frame / side rail as shown in Diagram 209."

Rule 209.1 Front bumper - Change upper bar / tube minimum from ".630" to ".625" and lower bar / tube minimum from ".787" to ".750".

Include the same wording from Section 200 for securing fasteners to Section 300 and 350. Along with allowing cotter pins and safety wires, also include the use of Spring Clips and E-clips with manufactured bolts / studs designed for their use.

ICC & ICA ENGINE HOMOLOGATION ANNOUNCEMENT

Engines homologated by the CIK in the ICC classes for 2004 will not be legal for the Daytona KartWeek Manufacturer's Cup and Road Race events December 27 - 30, 2003. In speaking with the CIK and visiting their Web site, the list posted is a provisional one. It will not become official until early next year. Once the 2004 homologation becomes official, WKA will make a decision when to permit the newly homologated motors to participate in the Manufacturer's Cup and Road Racing Series. Until then, only the motors already legal in ICA and ICC will be permitted to compete in those classes for the previously mentioned series.

NRRS ELIGIBLE ENGINES

The Dunlop Tire National Road Racing Series Spec 125 Sprint class eligible engines and technical inspection items have been announced for Daytona KartWeek. Legal engines include the Rotax Max and the Parilla Leopard. The Sonik VX125 will become legal March 1, 2004.

The 2004 WKA Technical Manual also lists the Comer as a legal engine for the Spec 125 Sprint class. The importer has just advised us that the required non-adjustable clutch will not be available until after January 1, 2004. As a result, this engine will not be legal for Daytona KartWeek, but will become legal as soon as the non-adjustable becomes available. Watch for a technical update for that announcement.

A non-invasive tech has been developed for the Spec 125 Sprint engines and will be in place at Daytona KartWeek. Tech will not require breaking the seal on Rotax engines or removing the cylinder head on any of the engines. The following items will be subject to inspection:

Engine displacement
Combustion chamber volume
Combustion chamber squish
Port height
Exhuast system
Reeds
Carburetor
Clutch

Note that the TAG engine clutches must be non-adjustable and supplied by the engine manufacturer or importer. They must remain unmodified and may not be lubricated to increase clutch slip at the start of a race.

All engine and clutch specifications have been developed from factory dimensions and validated through random sample tech inspection done during the 2003 season. They will be available at Daytona KartWeek and will be expressed in traditional or "Americanized" terminology. If your engine has not been modified in any way, you should have no concerns about passing engine tech at Daytona KartWeek.

More details on the non-invasive technical inspection will be available at Daytona KartWeek and will be published in an upcoming issue of WKA's Karting Scene and on-line at www.worldkarting.com.
