Has anyone out there done porting work / mods (besides mufflers) on these saws?
results,advice ,etc.

I just did my Makita DSC340. Opened up the muffler widened the exhaust port.
The saw is a screamer now. I was very impressed on the quality of the saw.
I wish I had a bigger one to try the same on. Anybody got a 40cc P/C???
Looks like a bolt one!!
