It all depends on the porting. Some piston ported cylinders have boost ports and small holes in the piston which match up to them.
do you know of an example or have photos of piston ported cylinder with boost ports or piston windows?
Malossi, eurokit,athena, k-star, for example. Check them out here http://www.mopedarmy.com/wiki/Puch_Maxi_Cylinder_Information
