In addition to the huge range aluminium cylinder kits Airsal has now expanded the product range with cast iron sport cylinders. Here, with this 70cc Airsal cast iron sport cylinder kit particular emphasis has been placed on the layout of the flow channels which were taken over by the precise Metrakit MK honoured sport cylinders. A 17.5mm carburettor is fully recommended, failing that, up jetting is a must. Supplied as per image including cylinder head.
