In this perspective, the very strict selections for the pairing between cylinder and piston are rigorously maintained within the maximum 20 micron tolerance range.\u003cbr\u003e\u003cbr\u003eThe cylinder kit offers an increase in power and torque thanks to the new cast iron cylinder, which, while maintaining both the bore and the connection technique to the muffler unchanged, has benefited from a total redesign that led to the complete replacement of the internal transfer ports, which now allows optimal mating not only with our crankcases, but also with original ones. In fact, mounting these cylinder kits on original crankcases only requires boring the cylinder liner passage.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e72_7084\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eCompared to the previous version: the exhaust has been revised both in its geometry, re-profiled and dimensionally varied, and in its timing, which has been matched to the intake timing; the intake transfer ports are perfectly symmetrical at the cylinder inlet and the flow paths have a completely different orientation of fresh gases at the chamber inlet. The big news is the rear transfer ports, which, subjected to a revision of the \"fingernail\" rear technique, now have an adequate inclination and, above all, a calculated progression of flow crossing areas. The union of the two rear ducts in the characteristic \"H\" shape allows for maximum exploitation of the pumping work, transferring the greatest possible energy with the least losses to the flows. These innovations result in greater uniformity of scavenging between the right and left sides, which leads to better combustion and, consequently, an incredible increase in the characteristic efficiencies of two-stroke engines.\u003cbr\u003eThe result?\u003cbr\u003eAn unparalleled increase in performance, which places our cylinders at the top of the range of cast iron cylinders on the market!\u003c\/span\u003e\u003c\/p\u003e","brand":"Malossi","offers":[{"title":"Default Title","offer_id":53566896046418,"sku":"316156","price":143.0,"currency_code":"CHF","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0945\/3771\/1954\/files\/gruppo-termico-73cc-46-5mm-con-spinotto-10mm-in-ghisa-per-piaggio-ciao-malossi_ffff81ec-43dc-49a3-a561-7c1b9dd6a545.jpg?v=1780928870","url":"https:\/\/mymoped.ch\/en\/products\/gruppo-termico-73cc-46-5mm-con-spinotto-10mm-in-ghisa-per-piaggio-ciao-malossi","provider":"MyMoped","version":"1.0","type":"link"}
