The Vortex Kiwi Mini ROK engine powers our two youngest Age Group Classes, Cadet ROK and Vortex Mini ROK.
Transition between these classes is very simple and inexpensive with just a change of the plug in RPM Limiter (from 11,000 rpm to 14,000 rpm) and a swap of exhaust header required.
Vortex has produced a comprehensive Installation, Run In and Service Manual. The Manual includes a list of tools required, step by step instructions with pictures, run in guidelines, service recommendations, key torque settings etc.
NOTE: FUEL, Vortex recommend 95 octane (RON) minimum.
NOTE: The spec oil Motul GP 2T must be used.
