Material: Aluminum Manufacturer: NC Motorparts Parts included: Cylinder, piston, piston rings, piston bolt, cams and gaskets as shown. Now we have two nice cylinders for Puch, art.no 15556 with twist and power in the lower speed registers, while this NC cylinder is much more peaky and suits those who like to drive with high revs. Both go best with Dellorto carburetors of size 16mm, not so important with the muffler choice but preferably Jamarcol, Sachs or Puch.

This was the max result with Sachs Jamarcol , Dellorto 16mm (NC special top was used together with NC cylinder) Picture 3 : Torque curves, same setup as picture 2. Red curve S2V 5.76 NM / 5850 RPM . Green curve NC 4.40 NM / 5600 RPM . Extra piston can be found on art.nr 23274 and extra piston rings on art.nr 18565
