Downsides to ported saws?

Nice. Still be cheaper than a Vitamix Blender.

We bought the factory refurb. Aluminum base and stainless jug. It rips.

according to the internets a 660 wont cut down a tree :msp_biggrin:

You're right. It won't cut down a tree. It usually cuts several. It doesn't like to stop with just one. And it does it day after day after day after....

Cons of port work is a little added cost and voided warranties. I can't really think of any disadvantages but I'm open to hear them.

Two very compelling reasons right there.

Where???

I don't see any...

What are you looking at??

I hope what I said didn't come off bad, I'm not against porting saws to say the least. However if you know anything about engines, you also know more rpm's, compression, heat and power, puts more stress on the engine. That is a cold hard fact. IMHO if you port as saw and it doesn't make enough extra power to shorten it's lifespan, you're doing something wrong lol.

Let me be honest here, and I don't care whose shoes I step on. I have several stock saws that will run with many true woods ported, non cookie cutter saws. IMHO most porting gains come from a simple MM, setting the squish and sometimes ignition work. Remember this is coming from someone that has ported a saw or two, but doesn't normally do it for monetary compensation.:msp_razz:

When it comes to increased production, all I've ever heard is second hand testimony, hearsay and what amounts to guessing. I truly wonder how big of a role perception plays when it come to increased production? What I'm saying is just a guess as well, so hopefully I'm wrong, as I sure do like a strong ported saw. I like asking the hard and unpopular questions, how else are we going to learn?

Aahhhh.....
I see now....

But you're used to slow saws...
I can tell by your equipment list...

Hmmm and Dennis doesn't buck too bad when I step on his shiney new shoes .......................

i think i need to buy some jb weld and unport my saws now .................jeesh this internet saw stuff is hard to keep up with whats better :hmm3grin2orange:

Not being a Pro Logger I doubt that any loss of longevity, if there really is any, would ever be noticed by a firewood hack like me. Porting is well worth the power to weight ratio increase.
It takes a good saw to the next level for sure. And the sound is so addicting, oh yeah!

That there is a good point...
If the expected service life of a saw were 2000 hours of run time, How many saws out of 100 sold, ever make it to half that?
Seems like something kills em' long before they ever wear out from use...

Ran over.
Straight gassed.
Dull Chained to death.
Dropped to it's death.
Tree fell on it.
Got stolen.

I just like the extra power and manners I get out of a good modded work saw... "And a small handful of stock models"
They just behave right...

Okay, thanks for all the replies. This really is a cool community, so many revhead chainsaw nuts in one place. So few who need to bignote themselves, so many who want to share their experiences and help others. Where else can you get the opinion of people who have run so many saws - and lets face it, the best you've run is the best you know.

Some people seem to think I'm anti porting, thats not true. I just dont believe that anything comes for free. I've been around enough modified engines of various types to not believe that its rarely all an upside. Probably the closest I can find to the "just everything gets better" are jap diesel motors. My guess is their standard tune is so poor due to emission laws, maybe its the same with chainsaws?
Cars in the 80's were the same, remove emissions crap, gain a better car.

Reading between the lines of whats been said about the Stihl models - porting brings the timing closer to what was standard in the 044/046/066 era. So perhaps it is just the fact that saws have been choked?

They keep me in firewood, and a nice warm house. :hmm3grin2orange::hmm3grin2orange:

To port or not to port... What a ridiculous question. While heat displacement seems like it would cause an issue, it doesn't. As a matter fact, most if not all ported saws, are muffler modded. That along with the porting itself causes an engine to run cooler. I don't pretend to know anywhere near the knowledge of randy or brad or stumpy or moody or anybody else but I have ported a saw of my own and it rips. I've also read Two-stroke tuner's guide by Gordon Jennings. Look it up. It's a really good read and will explain a lot about porting 2strokes and other stuff mainly motorcycles. In the start of the book, Gordon talks about the reasons of porting. Each engine is designed for the masses and everyone doesnt need a ported saw. Also, casting flaws ect... are the inevitable because of the nature of mass production. Read up on all that. This guy has a good bean on him. Now as far as a downside to a ported saw, the only complaint I can imagine is sound. Ear muffs should solve that. A sharp chain is the easiest mod but it doesn't change the personality of a saw like a good woods port. If someone studies up and knows enough to think they want port work done then they already know the importance of a sharp chain. You also could get into the different type of chains but I ain't going there. The coatings on the port chamfers are removed but some cylinders don't even have nikisil(or however it's spelled) coatings. I've tried to address as much as I could remember being mentioned to help the naysayers understand where we're coming from and maybe help them see the light. Lol

great............does anyone know the best way to get jb weld off aluminum ?
