Stage6 Cylinder Kit 70cc Sport MKII Yamaha BW's / Stunt – this is the redesigned and improved version of Stage6's extremely popular 70cc MK aluminium cylinder, developed and produced by MXS Racing and available at Maxiscoot for an excellent price. 

The kit includes:

Cylinder 70cc aluminium
High-compression cylinder head
2-ring piston, 10mm pin (10x36mm)
Gasket set
Stud bolts

This Nikasil-plated aluminium cylinder has 5 transfer ports and an oval-shaped exhaust port. As a sports cylinder with a 2-ring piston, it is suited for everyday use and robust, its 2-ring piston reducing wear and tear and as a result improving reliability and life expectancy. You can run this cylinder with your original set-up, provided that it's run with a 17.5mm carburetor.

Combined with a tuned set-up, meaning a racing exhaust, a sports variator, a 21mm carburetor and a digital inner rotor ignition (by Malossi), this kit will give you up to 17hp (!!), which is quite impressive as far as sports cylinders go.
