I am a newbie to chainsaws and am curious. Many people I have talked to say to get my new MS400 chainsaw ported. Why? What are the pros and cons? Really curious and trying to understand. What i have learned so far is a bit confusing.
Ported saws, depending on port work quality, dept of port work and/or operator usage:
- placebo effect, louder saws are faster/better
- wanting to run the smallest possible PH wearing the longest available B&C setup
- trade off for a well sharpened chain
- attempt to get a China made clone saw run as strong as it's original counterpart
- remove factory implemented restrictions that truly do rob power
- many will claim that they get done more with a ported chainsaw, I never noticed a measurable/noticeable production increase when swapping from a stock saw to a ported one though
Don't get me wrong, I own two ported saws (see sig) and they are high strung beasts.
Though, I personally feel they fatigue me more than my identical stock counterparts exactly due to their more volatile behaviour/characteristics.
Also, in the hard wood logs I tend to buck high chain speed is counterproductive and low end torque outweighs the benefits of high rpm.
Are there gains of porting as chainsaw?
Yes!
Does each and every chainsaw require port work?
No!
It depends on what You do with the saw(s) You own and whether the saws performance meets Your needs.
I muffler modded my Dolmar PS-7310 which featured a SLR muffler (exhaust scavenging, quite choked) and she turned from my least used large saw to my most used big chainsaw.

No, I did not read through all posts in this thread!
My guess is most posts tell You to port Your saw, but that is to be expected on a chainsaw enthusiast forum.
It is like asking whether You need to swap Your trucks factory sized steel rims with larger lightweight ones on a truck forum.
And, no I have no love for aluminum rims!
