STAGE6 70cc SPORT PRO MK2 CYLINDER KIT VERTICAL

The cylinder was completely redesigned; 6 instead of 5 transfer ports ensure optimized cylinder filling. The oval exhaust remained but was optimized as well. The appearance is based on the pentagonal shape of the R/T cylinders. The head is a one-piece unit with cast scavenging canals for better heat dissipation. The piston is a replica of the R/T piston, with a domed piston crown and 0.8 mm thick piston ring to optimise performance and improve thermal stability.

The cylinder delivers 2 to 3 hp more power than the MK1, between 12 hp, without any additional modifications and in combination with the corresponding components. Maximum performance and outstanding robustness - we are sure that this cylinder will set new standards in the tuning scene.

We recommend using a reinforced crankshaft, a min. 19mm carburetor and a sport / racing exhaust to exploit the full power of this tuning cylinder.

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.

NOTE: Original exhausts cannot be mounted with this cylinder.
