Hi Dillon

I would recommend a 7mm O/D high performance double insulated racing HT lead with copper core.

The core should be made up of 40 strands of 0.25mm copper (or similar).

Plug cap should have a 5K ohm resistance (NGK LB05EMH or similar) and you should always run an Iridium resistor racing plug with a fine wire ground-strap (NGK R7376-10 or similar).

The resistor plug and cap cut down electro-magnetic interference that can affect the CDI box

Best Regards

Ian :-)
