phazer specs are used as a guide but they will not work for the ex ..........for those that do not understand porting in 2 strokes you need to start reading and maiking junk if many cyinder designs .....there is no exact with porting but i have devoloped mine and take if further and further till things go down hill .........but i still have many tricks to take things up a notch............and no i will spill them
