<h2>Top Performances 85cc Engine Kit Minarelli AM6 – Cylinder + 44mm Stroke Crankshaft</h2> <p>The <strong>Top Performances 85cc engine kit for Minarelli AM6</strong> represents one of the most complete combinations of <strong>performance, reliability and durability</strong> among cast iron maxi kits. This set includes <strong>cylinder, piston and long-stroke crankshaft</strong>, offering a complete solution for high-level engine builds.</p> <p>The heart of the kit is its <strong>cast iron cylinder</strong> with a <strong>49.5 mm bore</strong>, fitted with a <strong>single-ring piston</strong> and a <strong>high-compression modular cylinder head</strong>. Combined with the <strong>44 mm long-stroke crankshaft</strong>, a final displacement of <strong>85cc</strong> is achieved, providing a very significant increase in torque and power.</p> <p>Thanks to its cast iron construction, this kit stands out for its <strong>high mechanical strength</strong> and ease of repair in case of seizure, a clear advantage over aluminium kits. Its <strong>bridge-less exhaust port</strong> and internal porting make it an ideal option for riders seeking serious performance without sacrificing robustness.</p> <p>With the proper setup, this kit can deliver approximately <strong>17–19 HP</strong>, and with larger racing carburetors and exhausts, it is capable of reaching much higher figures in advanced builds.</p> <h3>Installation recommendations</h3> <ul> <li>Minimum recommended carburetor: <strong>21 mm</strong></li> <li>Recommended exhausts: <strong>competition / racing</strong> (Yasuni R3, Pro Race, SCR Racing Line, etc.)</li> <li><strong>Attention:</strong> as this kit uses a <strong>44 mm stroke crankshaft</strong>, it may be necessary to <strong>machine the inside of the crankcases</strong> for correct installation.</li> </ul> <h3>Technical data</h3> <ul> <li><strong>Displacement:</strong> 85cc</li> <li><strong>Piston diameter:</strong> 49.5 mm</li> <li><strong>Cylinder material:</strong> Cast iron</li> <li><strong>Piston:</strong> 1 ring</li> <li><strong>Crankshaft stroke:</strong> 44 mm</li> <li><strong>Exhaust timing:</strong> 191°</li> <li><strong>Intake timing:</strong> 132°</li> <li><strong>Squish clearance:</strong> 0.9 ± 0.1 mm</li> <li><strong>Compression ratio:</strong> 8:1</li> <li><strong>Recommended ignition timing:</strong> 17° (1 mm before TDC)</li> <li><strong>Recommended spark plug:</strong> NGK BR10EG</li> </ul> <h3>Top Performances 85cc AM6 maxi kit contents</h3> <ul> <li>Top Performances 85cc cast iron cylinder</li> <li>Piston</li> <li>Needle bearing</li> <li>Modular cylinder head / combustion chamber insert</li> <li>Water plug</li> <li>Complete gasket set</li> <li>Reducer sleeve 28 / 25 mm</li> <li>44 mm long-stroke crankshaft</li> </ul> <p>A <strong>high-performance maxi kit</strong>, designed for those who want to transform their AM6 into an extremely powerful engine while maintaining the reliability that characterizes <strong>Top Performances</strong> products.</p>

<p>VHM connecting rod is a special lightweight conrod and must be used with the massive big end pin to ensure the best balance factor for minimum engine vibrations.<br /><br />The connecting rod has 20 grams less weight compared to the OEM connecting rod and improves throttle response.<br /><br />Through engine braking, standard big end hole of conrod deforms 0,015-0,02 mm oval, while our VHM conrod only deforms 0,005 mm (due to high strength material). In addition, this conrod is also super finished, which ensures a smooth surface. This helps prevent small fractures in the material.<br /><br />This connecting rod kit inlcudes the conrod, big end pin, big end bearing and washers.</p> <ul> <li>Lightweight</li> <li>Less oval deformation</li> <li>High resistance to fractures</li> <li>Improved throttle response</li> </ul> <p>Part number CRK1402</p> <ul style="list-style-type:disc;"> <li>Length (center to center) [mm] 96.00</li> <li>Big end bore [mm] Ø26.00</li> <li>Big end width [mm] 15.00</li> <li>Small end bore [mm] Ø18.00</li> <li>Small end width [mm] 14.00</li> </ul>
