78.5cc "Sport" Cylinder Kit (d=50mm) by Airsal.
The cylinder is made of Nikasil-plated aluminium and has 6 transfer ports, a bridged exhaust port; it comes with a high-compression monobloc cylinder head and a two-ring piston (d=50mm).
As a "Sport / Mid Race" cylinder, it has a lot of torque and good acceleration, especially in the mid rpm range. To get the most out of it, we recommend using a 17.5/19mm carburetor (at least) and a sports exhaust (such as Yasuni R2/Cross HM, SCR H.M, Metrakit RK Replica/SP, Hebo Performer, MVT Carrera, BRK, etc.). Just like with all aluminium cylinders, it is really important to adjust squish clearance to ensure reliability and performance of your engine (cylinder manual will tell you the proper value for squish).
