  2. Unleaded that is no more than 100 RON,
  3. Which contains no additives other than those added at the point of manufacture except for lubricating oil,
  4. Be a brand of fuel homologated by MA that is compatible with the Fuel Quality Standards Act 2000.
14.14.5.2 Leaded fuel, providing that:

  1. The fuel is purchased from suppliers approved by Environment Australia.

14.15 ENGINES

14.15.1 General

14.15.1.1 Engine capacity must not exceed 1300cc.
14.15.1.2 Period 6 only: overbore limit of 5% for engine reconditioning above the original manufacturer’s capacity.

14.15.2 Reciprocating Engines

The formula for calculation of capacities and classes

Cubic capacity = (D2 x 3.1416 x C x N)
4

Where:

D = Bore in centimetres,
C = stroke in centimetres,
N = Number of cylinders.

14.15.3 Rotary Engines

Cubic capacity = (Z x V)
N

Where:

V = Capacity of each chamber comprising the engine in cubic centimetres,
N = Number of turns of the motor necessary to complete 1 cycle in a chamber, and
Z = Combustion cycles per revolution.

14.15.4 Wankel System Engines With a Triangular Piston

Cubic capacity = 2 x V x D

Where:
V = capacity of a single chamber,
D = the number of rotors.
14.15.4.1 Wankel system engines are classified as 4 strokes.

14.15.5 Superchargers and Turbochargers

14.15.5.1 Superchargers and turbochargers may only be used as follows:

  1. In drag racing or record attempts,
  2. In Production Class or Improved Touring racing when fitted as factory equipment,
  3. The nominal cubic capacity of an engine as calculated under 14.15.2, 14.15.3 or 14.15.4 that is fitted with a supercharger or a turbocharger shall be multiplied by two for the purposes of engine classification,
  4. For Historic Road Race Period 2 machines, when fitted with a supercharger as factory equipment.

14.15.6 Engine Capacity Tolerances

14.15.6.1 The actual engine capacity of a machine competing in a capacity class in Historic Road Race may not exceed the prescribed capacity for that class by more than 5%.

14.16 FRAMES AND PARTS

14.16.1 Compulsory Modifications

14.16.1.1 The following parts must be removed from any machine before it may be entered in a competition:

  1. Headlamp,
  2. Tail lamp,
  3. Traffic indicators,
  4. Reflectors,
  5. Horns,
  6. Rear vision mirrors,
  7. Centre, rear and side stands,
  8. Registration plate and label holder.
14.16.1.2 Any sharp edges left by the removal of these components must be protected by a rolled edge or beading of a minimum diameter of 3mm.

14.16.2 General Frames and Parts

14.16.2.1 All machines must be fitted with a functioning engine cut out switch which must be either a lanyard type or handle bar mounted.
14.16.2.2 Plugs or caps which, if removed, permit the discharge of any lubricating, cooling or hydraulic fluids must be lockwired or otherwise secured in the tightened position in a manner approved by the scrutineer. All high pressure oil lines to be secured by a pressure type fitting on Period 4, Period 5 and Period 6 machines. Worm drive hose clips may be used on Period 1, Period 2 and Period 3 machines.
14.16.2.3 All hoses must be securely fitted and guarded to prevent contact with:

  1. The ground
  2. Tyres or other moving parts over the full movement of the suspension
14.16.2.4 All machines must be fitted with an oil catch tank of a minimum capacity of 500cc, to be emptied at the end of each race.
14.16.2.5 The only liquid coolant permitted is water. No additives allowed.
14.16.2.6 A self-closing throttle must be fitted.
14.16.2.7 Four-valve heads are prohibited in all periods unless originally fitted by the manufacturer, or were a proven period modification.
14.16.2.8 Front and rear brake caliper mounting bolts to be lockwired in the tightened position.
14.16.2.9 Frame protection devices may be added providing they do not protrude more than 80mm from the bodywork and are no more than 80mm in diameter.
14.16.2.10 Where the exhaust system or swing arm does not shield the sprocket a chain guard made of suitable material must be fitted in such a way to prevent trapping between the lower drive chain and the final drive sprocket at the rear wheel.
