Stage6 cylinder kit Racing MK 2 70cc<\/h2>\n

Stage6 Cylinder Kit 70cc Racing MK2 10mm piston pin Minarelli horizontal LC<\/strong> (Yamaha Aerox \/ MBK Nitro). The successor of the successful Stage6 70cc racing cylinder is called Stage6 Racing MKII 70cc and was completely redesigned for even better out of the box performance.<\/p>\n

For 50cc scooters with Minarelli horizontal LC engine such as MBK Nitro or Yamaha Aerox.<\/p>\n

Cylinder Design Stage6 MK2 Racing<\/h3>\n

The cylinder with high-strength hard chrome bore plating was completely redesigned<\/strong>. A new transfer port design (6 instead of 5 ports) improves cylinder filling. The piston is no longer flat but domed, with a 0.8 mm thick piston ring to optimise performance and improve heat dissipation. Thermal properties were improved in all areas. Generous flushing of the bridged exhaust port; a pentagonal design and internal cooling ribs; one-piece head with cast scavenging canals \u2013 to name but a few of the improvements. Port timings are 190\u00b0-130\u00b0.<\/p>\n

Performance Stage6 MK 2 Racing Cylinder<\/h3>\n

The cylinder yields 2 to 3 hp more power than the MK1, between 17-19 hp<\/strong>, without any additional modifications and in combination with the corresponding components. There is enough material for further modifications to get the cylinder above 20 hp. Definitely one of the most powerful 70cc kits on the market!<\/p>\n

For race setups with big carburetors and high revving exhausts, we highly recommend the use of the 12mm piston pin version of this cylinder kit\u00a0(S6-7416608<\/a>).<\/p>\n

We recommend using a reinforced crankshaft, a min. 21mm carburetor and a racing exhaust to exploit the full power of this tuning cylinder.<\/p>\n

Installation tips for Stage6 mk2 Racing cylinder Kit<\/h3>\n

We recommend to clean the engine before assembly, check the condition of all components and use a new spark plug and new small end bearing. Do not forget to change your carburetor settings if necessary.<\/p>\n

Squish clearance should be between 0.75 and 0.85. The cylinder should be run in for approx. 300 km with a 1:33 mixture to improve robustness and life expectancy.<\/p>\n

Attention:<\/em><\/p>\n

– Original exhausts cannot be mounted with this cylinder.
– The temperature sensor (including thread) may not be longer than 18mm, otherwise it may knock against the cylinder head.<\/p>\n

WITHOUT HOMOLOGATION (in some countries)<\/p>\n
