Ted Boyko began porting cylinders 45 years ago, when the two-stroke craze was at its peak, and he's still

Crankcase and Cylinder porting is probably the most controversial subject among Performance 2-Stroke engine builders. Part of the problem is understanding the "pulse" or "charge" nature of the airflow in a 2-stroke engine. The other is how "Air Density" (barometric pressure, temp, humidity), and Elevation Change, affects
