I realize that I am a newbe around here and I am fascinated about how you guys soup up these chainsaws.
A ways back when I was a lot younger I used to race MX bikes.We used to soup them up too.We used to dril holes in the piston skirts on the intake side.Some of them came that way.The reason this was done was to use the gasey air trapped under the piston for more power. I assumed that is what the windowed piston in some of these pro saws was for.
I noticed the other day at another site that a guy said he was using a Stihl 028 46mm windowed piston
in a Husky 55 open port.He said it gave him more power.I know the piston is made for a closed port and would not be as efficient in an open port. But could it not be some advantage?
