Porting the 395xp

[stihl038x2]

Hey folks, got a 395xp to port. I've done a ton of Stihls so am new to the "BIG DOGS". Does anyone have info. to share on these, maybe a build thread I've been unable to find.......or PM me if you want to keep things on the "hush".

Thanks,

Steve

It seems very mild.......but that's the way the winning saw at the 395 build off was done.

Our 395s got first, third, and fouth.

All done the same way?

Pretty wide intake duration compared to most.

Yes sir.

We were cutting 16 8" X 8" cants banded together. Being able to hold RPM in the cut was the most important aspect. So our standard woods port was what was needed.

I've found that when we have these build offs, most guys over port the saw. Torque suffers and they lose.

Just where the machine work took it too.
