The minimum volume of the Combustion chamber is 14 cc, measured in accordance with KA cc measuring method. No material may be added to the cylinder.

d) Cylinder may be modified except in the following areas: i. Volume of transfer ducts ii. Exhaust duct length iii. Internal profile of the exhaust duct outlet iv. Maximum ports chord width and lower gasket plane of the cylinder according to the

Homologation Form These elements cannot be modified or altered in any way or method and are control surfaces and areas

e) The upper cylinder plane may be repaired but must comply with all dimensions contained within the homologation form.

f) The cylinder ports and passages cannot be modified in any way, and must remain in their original form and conform to the homologation document.

g) It is allowed to replace the spark plug thread by a heli-‐coil h) Power-‐valve is strictly forbidden i) Crankcase/Crankcases may be modified to conform to the new production methods. Crankcases must be

in conformance with either Diagram A, Diagram B or Diagram C in Appendix 2 of these Regulations. j) The crankcase pin is able to be modified k) The drive-‐side balance shaft cover is able to be machined to fit an o-‐ring in aid of sealing the outer edge

2.3 Maximum Theoretical Bore Size

a) The Maximum permitted theoretical bore size is 54.48mm

2.4 Spark Plug a) Spark plug make is free. b) The body of the spark plug (electrodes not included) tightened on the cylinder head, must not extend

beyond the upper part of the dome of the combustion chamber. c) Spark plug must comply with the images in Appendix 3 of these Regulations.

2.5 Ignition a) CIK-‐FIA homologated ignition system complying to either of the following Homologation Documents must

be used: i. 57/1/15 ii. 57/1/15-‐01/01/ET iii. 57/A/18

b) The Engine RPM is limited to 14,000rpm


c) The engine ECU program/software cannot be altered or modified d) On decision of the Stewards or Technical Official, they shall be authorised to interchange any part or all of

the Entrants’ ignition systems for the system supplied as original equipment at their discretion for the purpose of checking conformity.

2.6 Exhaust

a) Must be the homologated exhaust for the engine being used. b) Cannot be altered or modified c) The exhaust spacer length is free to a maximum of 20mm OEM spacers. These spacers must be used

without modification d) A maximum of one gasket per face of the spacer is permissible

2.7 Reed block

a) The Original Vortex KF3 Reed Valve Pyramid Intern. Conveyor as supplied with the 39/M/18-‐KF3 engine with no modifications must be used.

2.8 Carburettor

a) The Carburettor must be a 20mm Tryton KF3VAMEC b) Maximum diameter of 20mm c) Must comprise of two set screws d) Must remain strictly original and comply with the CIK-‐FIA Homologation Document 26/C/15 e) The Original Vortex KF3 Carburettor Manifold shall be used as supplied with the 39/M/18-‐KF3 engine with

no modifications permitted. f) Any form of spacer between the Carburettor and the manifold other than a gasket is strictly prohibited.

2.9 Air Box (Inlet Silencer) a) The Inlet Silencer can be either a:

i. KG P.No.FA006AG with 23mm ran tubes, or ii. The alternate air boxes with maximum 23mm ram tubes only all other dimensions as per

Appendix 3 of these Regulations. iii.

2.10 Clutch a) Must comply with CIK technical drawings No.15, 15b & 16 (Appendix 4 of these Regulations) b) Minimum weight (complete clutch with starter ring and engine sprocket) according to the relevant engine

Homologation Document c) The engine clutch must be triggered at 3,000 rpm maximum and make the kart with the Driver on board

move forward; it must be in direct drive (and 100% engaged) at 5,000 rpm maximum under all circumstances.
