VORTEX MINI ROK HOMOLOGATION UPDATED
09.06.26
The Homologation Document for the Vortex MiniRok engine has been updated with immediate effect.
Over the past few months, Karting Australia has worked with the engine manufacturer to provide an improved fuel system, particularly for Cadet 9 competitors. As a result, the Homologation Document has been updated to permit the fitment of a fuel return line using a standard T-piece fitting (OTK Part No: 0281.AA). No other modifications to the fuel system are permitted.
The fitment of a fuel return line is optional and is not a compulsory change to the engine set-up.
