The cast iron cylinder kit from Naraku for all air-cooled horizontal Kymco engines (SF10) is a high-performance 70cc kit that won’t sit down and beg. The cylinder features 6 overflow ports and a large oval outlet port. The kit can be used with the original head. The cast iron construction means this cylinder is great value for money. Due to the somewhat sharp timing, we recommend using a 17.5mm carburettor to ensure durability and avoid chewing pistons. The cylinder can take systems such as Tecno, laser, Tecnigas or Hebo Performer. Can also be used with the standard system, but with less of a performance increase.
