Stock OEM frames required. No modifications to any portion of frame allowed, unless specifically noted.

ALLOWABLE MODIFICATIONS:

ALL BIKES: Frames may be polished, chromed, painted, powder coated, or otherwise cosmetically altered, as long as such modifications do not remove substantial material or weaken the frame. No braces, gussets, or crossbars may be removed, unless specifically listed. Additional braces, gussets, or crossbars may be added, as long as they do not weaken the frame in any manner.

Small accessory brackets, tabs, mounts, etc., using fasteners no larger than 5/16”(8mm) may be removed, relocated, or modified. New accessory mounts may be installed, and new mounting holes may be drilled into the frame, as long as the hole size does not exceed 5/16” (8mm). An excessive number of mounting holes will be considered lightening of the frame, and is not allowed. Exhaust mounting brackets, center-stand, and side-stand brackets, regardless of fastener size, may be removed as long as doing so does not weaken the frame

Steering heads must remain stock, with the exception of the bottom steering stem bearing race. The bottom bearing race cup may be re-machined to allow the bearing race to be recessed farther into the frame. New bearing race cup must use the factory bearing race. The bearing race cup must be machined along the same axis as the original location, i.e., the rake of the steering stem may not be altered during this modification. The original bearing race cup may be machined off to be flush with the bottom webbing of the steering neck, but no farther. No other material may be removed from the steering neck casting, with the exception of removal or modification of the steering stops and/or the headlight/fairing mount.

Seat rails/sub-frames may be modified or relocated. Mounting tabs or brackets for these items may be modified or relocated as well.

Rear suspension mounts including shock mount and rising rate linkage mounts may be relocated. However, due to the extreme loads and potential safety issues, modifications to these components will be heavily scrutinized. Swingarm pivot mounts may not be modified. Swingarm pivot centerline cannot be moved in any manner, including offset bushings, plates, etc. Proper design, welding, and bracing are crucial in these areas.

Engine mounting tabs and brackets may not be modified. Bolt-on engine mounts may be replaced, but must maintain the same mounting dimensions as the factory mounts. Engine relocation in any manner is not allowed.

HONDA BLACKBIRD: The round tubular cross-brace, located directly behind the steering stem, may be removed. Upper rear sub-frame mount may be removed. It may be cut off flush with the top of the factory frame spar, but no farther.

KAWASAKI ZX-12, ZX-14: Airbox inlets may be welded shut, or modified for better sealing with turbo dump pipe, as long as these openings are not enlarged. Access panels for throttle body/airbox connectors may be modified, as well as the mounting area for the connectors. These modifications may not weaken the frame.

All injectors controlled by factory ECM must be mounted in OEM throttle bodies in original location. Approved aftermarket inline plug-and-play engine management tuning boxes may be used to adjust ECM.

EFI turbocharged entrants may use “piggy-back” fuel-only management systems. These systems may control a maximum of 1 injector per cylinder mounted in the intake plenum system. Alternately, bikes originally equipped with 2 injectors per cylinder may utilize one injector mounting location per throttle body to mount the piggy-back injector. Fuel management systems may only utilize inputs from engine RPM, manifold absolute pressure (MAP), and throttle position to control fuel delivery. No inputs from any other source, including any data-logging channels, may be used to alter fuel delivery. No part or function of the piggy-back system may be used to adjust the ignition system or ECM.

NITROUS ENTRANTS w/ OEM ECM: EFI nitrous entrants running under this classification must utilize the OEM engine control module (ECM) to control the ignition system and primary fuel delivery. Approved aftermarket inline plug-and-play engine management tuning boxes may be used to adjust ECM.

Additional fuel may be added utilizing conventional “wet” nitrous injectors, or utilizing a “piggy-back” fuel-only management system. Piggy-back fuel systems may control a maximum of 1 injector per cylinder, and may only utilize inputs from engine RPM, manifold absolute pressure (MAP), throttle position, and nitrous progressive percentage to control fuel delivery. No part or function of the piggy-back system may be used to adjust the ignition system or ECM.

NITROUS ENTRANTS w/ AFTERMARKET EMS: Any legal aftermarket engine management system (EMS) may be used (see 2.8.4.2). The EMS may control all fuel, ignition, and nitrous functions.

4.3.1.10 RIDER

4.3.1.10.1 QUALIFYING
Riders of Super Street must hold a AMA Dragbike Class 3C license.

4.3.1.10.2 *ELIGIBILITY
Any rider who wins a championship in Super Street loses eligibility to race in this class for three years. Therefore, the class champions from the 2005 and 2006 seasons are not eligible to compete in Super Street in 2008. The 2007 champion is only eligible to compete in 2008 if they are using their option to defend their title plate (See DEFENDING TITLE section). In addition, the 2004 champion is also ineligible for the 2008 season if the 2004 champion chose to use their option to defend their title plate during the 2005 season.

PRO STREET CHAMPIONS: Anyone winning a Pro Street championship loses eligibility to compete in Super Street for five seasons. Therefore, the Pro Street champions from the 2003, 2004, 2005, 2006, and 2007 seasons are not eligible to compete in Super Street in 2008.

DEFENDING TITLE: In order to allow first-time champions to defend their #1 plate, any rider winning the Super Street championship and whom has never previously won a championship in either Super Street, Pro Street, or Street Bike Shootout, may run in Super Street the season immediately following their championship season. This Super Street title defense option is only available once in a rider’s career, immediately following their first championship season. If a rider chooses to use their title defense option, their three years of ineligibility begins following their title defense season, regardless of whether they win the championship that year or of the number of events they enter. A rider that has won a Pro Street or Street Bike Shootout title in any previous year is not eligible for this title defense option.

NOTE: Champions are only officially recognized at the end of a season. Even if a rider earns enough points to mathematically clinch a championship prior to the completion of the World Finals, they are not considered to have earned the championship until the completion of the World Finals. Therefore, issues of eligibility and ineligibility are not base upon calendar years, and can only begin and end after the completion of the World Finals each year.



RST Competitor Jeremy Teasley
 
4.3.2 *REAL STREET CLASS REQUIREMENTS

DESIGNATION: RST, followed by rider number.

A true entry-level, limited budget class, Real Street is an exhibition class designed to give the entry-level racer a place to compete in heads-up, no breakout competition. Almost any racer currently competing in any Street ET class around the country can bring his or her bike, with little or no modifications, and experience true heads-up racing for the first time.

With no limits on internal engine modifications, the much-feared post-race teardowns will be avoided. Instead, power levels will be controlled by limiting fuel delivery to only that which can be fed via stock fuel injectors. This approach simplifies the tech procedures following record-claiming runs and pos trace inspections. Only a minimal amount of disassembly will be required, because engine inspection will consist of only a flow check of the injectors.

Each bike may be required to compete in a 10-mile road course to prove street ability at selected events.

Ballistic blankets are not required for any entrants in this class.

This class is run as a “heads up” no break-out eliminator with a qualified field up to 32 motorcycles on a (.400) Pro tree.

4.3.2.1 ENGINE

4.3.2.1.1 GENERAL
Any internal modification is permitted. OEM engine cases and cylinder head casting must be used, but may be modified. Engine covers and crankcase breather covers may be replaced.

4.3.2.1.3 FUEL INJECTION
Only motorcycles originally equipped with electronic fuel injection may use fuel injection. All fuel supplied to the engine must be supplied by a single OEM fuel injector per cylinder. No extra injectors, “piggy-back” fuel systems, “wet” nitrous systems, fuel jets or bleeds, “leaking” fuel lines or seals, or any other method allowing additional fuel into the engine are allowed. Any competitor found to have such equipment will receive a mandatory minimum suspension of 3 races, and a forfeiture of all points earned up to that point in the season.

DUAL INJECTORS: Any bikes originally equipped with two injectors per cylinder are allowed to compete. However, on any entrant utilizing a turbocharger, supercharger, or nitrous, the use of any components that would allow both injectors to operate simultaneously during race conditions is prohibited. Any competitor found to have such equipment will receive a mandatory minimum suspension of 3 races, and a forfeiture of all points earned up to that point in the season. (removed 3/25/08)

ELECTRONIC CONTROL BOXES: Aftermarket fuel injection management systems that allow fuel or ignition timing adjustments are allowed. All units must be AMA Dragbike approved and available for immediate shipment from U.S. warehouses to any of the manufacturer’s U.S. retail outlets for sale to the public. Availability must be maintained throughout the current racing season.

Approved units that plug directly into the unmodified OEM wiring harness are allowed. Additionally, control units that require modification to the factory harness may be approved on a case-by-case basis by AMA Dragbike Tech. Any approved unit must be installed EXACTLY as per manufacturer’s instructions. Any deviation from manufacturer’s instructions is grounds for immediate disqualification for the remainder of the event.

On dual injector-equipped entrants (except naturally aspirated only), the use of any aftermarket control box, or the use of more than one aftermarket box in an attempt to operate both sets of injectors is not allowed.

FUEL INJECTORS: Stock OEM fuel injectors only. As part of the post-race teardown, tech may remove and flow-test injectors to verify that they are within factory flow characteristics.

FUEL DELIVERY: Fuel pump, pressure regulators, fuel lines, filters, and fuel rails may be replaced with aftermarket components.

THROTTLE BODIES: OEM throttle bodies must be used. Throttle bores may be modified, and throttle plates and shafts may be modified or replaced. Secondary throttle plates (if originally equipped) may be modified, deactivated, or removed. No modifications to the fuel injector bores or mounts are allowed.

Riders of Real Street must hold an AMA Dragbike Class 3C license.

4.3.2.10.2 ELIGIBILITY

Any rider who wins a championship in Real Street loses eligibility to race in this class for three years. Therefore, the class champions from the 2005 and 2006 seasons are not eligible to compete in Real Street in 2008. The 2007 champion is only eligible to compete in 2008 if they are using their option to defend their title plate (See DEFENDING TITLE section). In addition, the 2004 champion is also ineligible for the 2008 season if the 2004 champion chose to use their option to defend their title plate during the 2005 season.

PRO STREET & SUPER STREET CHAMPIONS: Anyone winning a Pro Street or Super Street championship loses eligibility to compete in Real Street for five seasons. Therefore, the Pro Street, Streetbike Shootout, and Super Street champions from the 2003, 2004, 2005, 2006, and 2007 seasons are not eligible to compete in Real Street in 2008.

DEFENDING TITLE: In order to allow first-time champions to defend their #1 plate, any rider winning the Super Street championship, and whom has never previously won a championship in either Real Street, Super Street, Pro Street, or Streetbike Shootout, may run in Real Street the season immediately following their championship season. This Real Street title defense option is only available once in a rider’s career, immediately following their first championship season. If a rider chooses to use their title defense option, their three years of ineligibility begins following their title defense season, regardless of whether they win the championship that year or of the number of events they enter. A rider that has won a Pro Street, Streetbike Shootout, or Super Street title in any previous year is not eligible for this title defense option.


NOTE: Champions are only officially recognized at the end of a season. Even if a rider earns enough points to mathematically clinch a championship prior to the completion of the World Finals, they are not considered to have earned the championship until the completion of the World Finals. Therefore, is
