7.B.2.5 Fuel Shutoff:
Fuel motorcycles must have a fuel shutoff operable without moving the hands from the handlebar grips; with the exception of nitrous systems with gravity feed which require handlebar shutoff for all but gas tank petcocks.
7.B.3 Throttle:
A self-closing throttle must be fitted to all motorcycles.
7.B.4 Controls:
Control levers must have at least a ½ in. diameter round ball end. The handlebars must locate the hands outside the width of the fork tubes (6 in. minimum). It is suggested that the configuration of the handlebar(s) locate the thumbs at least 10 in. apart. An entrant may be required to demonstrate low speed handling and stability to meet this requirement. The rider must use the handlebar(s) during the entire run. Fork stops must stop fork travel before the hands touch any other part of the motorcycle. No decorative bar ends or pegs.
7.B.5 Headlight and other lens:
All glass lenses must be taped to retain breakage. On headlights, the tape is limited to the glass lens. To avoid heat build up, lamps may be rendered inoperative.
7.B.6 Mirrors:

Tubeless, bias ply type tires may be run with tubes. Tires designed for use on the drive wheel in drag racing will not be allowed. It is the responsibility of the entrant to check inflation pressures and tire and wheel condition immediately before and after every run.
All motorcycle entries, including streamliners and sidecars, must use tires with an appropriate speed rating. The required speed rating is governed by the record speed in the class entered. Tires rated H CANNOT be used beyond the speed rating. Any run in excess of 200 MPH requires that the contestant examine tires for apparent deterioration or damage before further runs are conducted.
0 to 70 MPH Any tire designed for motorcycle use is permitted
71 to 130 MPH Production tires with a speed rating of H or higher.
131 to 150 MPH Production tires with a speed rating of V or higher.
151 MPH+ Production tires with a speed rating of ZR or special tires for racing as designated by the
manufacturer. Production tires with a speed rating of V, if shaved, can be used up to 200 MPH.
200 MPH + Experience has shown that using tires with hard rubber compounds and reducing the tread thickness by 2/3 by carefully shaving the tread provides the best results.
265 MPH+ Contestants must use LSR or other racing tires rated for speeds higher than the class
record.
Any tire deviation must be submitted to the Board, with sufficient supporting data to justify a deviation, in writing at least 45 days prior to the meet. Due to the duration of this event, rear drag tires are not acceptable.
7.B.9 Valve Stems and Caps:
All tire valve stems must be fitted with metal valve caps. Over 175 MPH, tubeless tires must use metal valve stems. Tube type tires with rubber valve stems that are angled relative to the rotational plane of the wheel must have those valve stems secured to resist centrifugal force deflection. Safety wire or other approved restraining device is required.
7.B.10 Wheels:

7.J ENGINE CLASSES
7.J.1 Production:
Production engines must be the same model as the model of the frame being used and must have STOCK
EXTERNAL APPEARANCE. Production motorcycles must use OEM cylinders, heads and crankcases to comply with this class. OEM engine displacement determines the displacement class for competition. Displacement may not be increased beyond that class limit. Starting mechanism must be retained and operable. Carburetors or throttle bodies must be OEM for that model production engine. All production engines run in gas class. See Section 7.D.3
7.J.2 Production Push Rod:
Same as Production, but must have pushrod operated valves with camshaft located at least one crankshaft stroke below the OEM cylinder deck position or utilize OEM pushrod length at least twice the crankshaft stroke.
7.J.3 Production Supercharged:
Same as Production, but an original brand factory installed turbocharger or supercharger is required.
7.J.4 Production Vintage:
Same as Production but must have been produced prior to 1956.
7.J.5 Class F:
Unlimited in design, but must be comprised of major parts and components designed primarily for use in motorcycle engines. No restrictions on fuel. Superchargers or turbochargers are not permitted. Fuel injection is permitted.
7.J.6 Class G:
Same as Class F, except it is limited to event gasoline.
7.J.7 Class BF:
Same as Class F, except supercharger or turbocharger is required and must be mechanically or exhaust gas driven and must pressurize the intake system above atmospheric pressure. No restrictions on fuel.
7.J.8 Class BG:
Same as Class BF, except it is limited to event gasoline. See section 2.B. Water injection is allowed, but water tanks must be inspected and sealed prior to each record run.
7.J.9 Class PG and PF:
Any motorcycle engine with push rod operated valves. The camshaft must be located at least one crankshaft stroke below the OEM cylinder deck position or that utilize OEM pushrod length at least twice the crankshaft stroke.
Replacement heads must have the same number of valves as originally produced as a production engine. “G” designates a gasoline engine and “F” a fuel engine.
7.J.10 Class VG and VF:
Same as Class G or F, except that the class is limited to motorcycle engines produced prior to 1956.
For reasons of historical authenticity, vintage engine modifications are restricted to older technology levels as far as practical. Accordingly, in classes VF, VG, VBF and VBG newer technologies such as EFI, or electronic reactive ignition systems are not in keeping with the spirit of the Vintage classes and are not allowed. Computers are allowed for data collection purposes only.
Engines must utilize OEM crankcase, OEM cylinders on flatheads and two strokes and OEM heads on OHV engines. Above components made after 1955 and exact reproductions may be considered legal in Vintage classes if they offer no competitive advantage. Pre installation approval by the board is required. It is the entrant’s responsibility to provide documentation and samples. A .050 in. overbore is allowed on vintage engines only (including production vintage) and will be discounted when the bore size is measured. Flathead engine displacement will be discounted 33 1/3% in determining engine displacement class limits. For example, a 1500cc measured displacement would run as a 1000cc.
7.J.10.1 Class VBF and VBG:
Same as class VF or VG, except that a supercharger is required and must be mechanically or exhaust gas driven and must pressurize the intake system above atmospheric pressure.
7.J.11 Class PBG and PBF:
Same as Section 7.J.9 above, push rod classes, except that a supercharger or turbocharger is required; subject to the same limitations as Classes BF and BG, respectively.
7.J.12 Class UG and UF:
Any reciprocating engine which uses the Otto cycle may run in Streamliner category only. Supercharged engines do not advance class size.
7.J.13 Class Ω (O - Omega):
An engine using a thermodynamic cycle other than Otto. This class includes electric, steam and turbine engines. Entry must comply with all applicable frame class requirements. Entrant must submit complete power plant details to the technical committee for safety evaluation at least 45 days prior to the meet.
7.J.14 Engine Displacement Classes:
Engine Classes are shown in cubic centimeters. 50, 100, 125, 175, 250, 350, 400 (ECTA Only) , 500, 650, 750, 1000, 1350, 1650, 2000, 3000 and 3001+ where permitted.
7.J.15 Maximum Displacements & Engines:
See section 7.D.4 on page 74.
7.J.16 Engine Cycles:
At the discretion of the Technical Committee, some engine classes may be separated into two categories. Two stroke and Four stroke. The engine displacement will be followed by a /2 or /4 for classification. Examples: APS/G-750/2 or P/PP-1350/4. Rotary engines may be included in this subdivision. Example: APS/G-750R. Two stroke engines are limited to 1000cc.
