The most powerful 70cc kit of cast iron kits for liquid horizontal minarelli. The pink top with stud bolt option has a range of high-end technical features. The pink cast iron cylinder treated MINACROM (cast iron has added chrome) has 8 transfers and a normal exhaust. This normal exhaust (in one part) is specially shaped and will preserve solidity in full power thanks to its unusual diagrams, the emission diagrams are at 127 ° and the geometric compression ratio of 14: 1 (effective 7.3: 1). The cylinder head has a 2-part stud will provide you with much more efficient cooling, therefore additional strength, less wear and above all maximum performance.
The finish of the cylinder is excellent. The silver-treated piston is in a single domed chrome s10 segment to allow very high speeds. In short, top performances as always hit hard, this cylinder is really overpowered (14hp max) and very torquey while preserving maximum strength. Mount it with a squish between 0.9 and 1mm, the cylinder head tightening should be around 15 + 1 NM. Now a prepared version exists, you can take a look here . The 8 intake transfers are not here for the sake of the sun or the trade, they are there to improve the sweep which is quite bad on horizontal minarelli, they really allow an additional performance without compromising the reliability, moreover the channels of transfers are very well studied.
We recommend to accompany this kit : crankshaft and reinforced bearings, racing exhaust (the tpr nardo will suit perfectly, minimum 21mm carburetion, cold spark plug, removal of separate greasing, mixture with 100% shyntese oil.
