Polini 70 Evolution cylinder kit
Described as the " most advanced cylinder kit for MBK Booster and vertical Yamaha Minarelli engines, this comprehensive performance improving cast iron kit has been " completely redesigned with exclusive technical solutions never seen before on these kinds of engines ". The heart of the kit is a combination of parts developed to maximise the fluid-dynamic yield and efficiency. It features an improved reed valve housing, integrated into the cylinder with two dedicated ducts that feed directly into the transfers: " an exclusive solution that improves the torque and the response at low rpm ". There is a four-petal reed valve( compared to the traditional two-petal ones) supplied in the kit, to increase and speed up the air / fuel. The dedicated flow guide is designed to better canalize the flow between the manifold and the reed valve, reducing
turbulence and loss of charge. A 360 ° routable intake manifold is compatible with the Polini CP carburettor taking the venturi from 17 mm to 24 mm. For complete flexibility during the assembly phase, this system allows the use of either a genuine replacement or open filter. The racing head has a copper gasket, with dual-ring piston and 0.2 and 0.3 mm base gasket to customise the squish. Two versions are available: 166.0074 / E with 10 pin or 166.0074 / 12E with 12 pin. With a basic setup, the Polini 70 Evolution cylinder kit delivers around 14 real horsepower, with a strong and full torque curve across the entire power output- " a major step forward compared to traditional 70 cc cast iron kits." Optional kit component upgrades include a 19 to 24 mm CP carburettor, Polini For Race or Scooter Team exhaust system and a High-Speed transmission.
