Description
Athena 80cc "Sport Pro" Cylinder Kit (43mm stroke) for MBK Booster / Stunt (Minarelli vertical).
Kit includes:
- Nikasil Aluminium cylinder, with 5 transfer ports and trapezoidal "single" exhaust port
- Single ring piston, 12mm trunk
- Monobloc high compression cylinder head
- Gasket set for squish fitting and adjustment
Being the "big brother" of the 70cc Sport pro cylinder kit, this kit has the same technical specifications, but has to be used with a 43mm crankshaft (and 85mm connecting rod).
this kit will give you 80cc with very impressive acceleration.
With a 21mm carburettor and a racing exhaust you can easily get 14 / 15hp on Minarelli upright engines. It is also an ideal cylinder to work on due to its capacity and high quality workmanship.
Note: as with all aluminium cylinders, you will need to adjust squish to ensure reliable performance and maximum power.
