Cylinder kit without cylinder head from the quality brand Gilardoni italkit.
The racing cylinder has 47 mm (75 cc).
This is a highly modern cylinder kit for racing use – the most powerful among the 47mm cylinder kits.
The Nikasil-coated bore guarantees durability and excellent emergency running properties (cylinder is less prone to tarnishing). Thanks to the generously designed intake tract and the high-quality 4-flap diaphragm, a super filling value is achieved.
In combination with the sharp timing of the cylinder, outputs of up to 10 hp can be achieved with the appropriate setup.
In order to get the full power from this cylinder, at least a 19 mm (ideally 21 mm) carburettor should be installed in combination with a racing exhaust.
Attention: Engine housing must be milled out.
Quality product from the Italian manufacturer Gilardoni under the italkit brand.
