Hey so how much does it cost to get my 661 ported? You got me thinking I need to let her breathe better!
 
Well if you get past my critical comments you know what you're doing at least, thats my aim - not criticism.
At the sales marked I would never consider a templed with saw, because I don't know exactly whats done with it.
A perfectly stock Stihl or Husky 92cc, thats clean sheets and something might worth investing in.
Anyway whenever I see this I cant help thinking to my self; a 661 + 300 dollas - perhaps you bought the wrong saw in the first place...

It would be the 881……much heavier and a lot more $$$
And your bars don’t fit.
Where as a port job gaining 35-40% in HP ………you have gone up a class
A port job usually means stepping up a class in power
A 60cc doing the job of a 70cc easily with less weight.
And ported saws run cooler and last just as long or longer
Just saying what I’ve seen happen

So, a MS661 is at about 5,4kw / 7,25hp, you saying that he will get 7,5kw / 10hp from that saw without compromising torque or sustainability?
I simply don't think that will be true, sir.
 
Alright, I trust you...... good luck with that.
There are dyno sheets of before and after. Some saws only gain 15-20% while others end up with 40-45% more hp. A woods ported 65cc saw can be up over 8.5 HP. My 661 is 10.5 HP and I know of others that are over 11.
 
Yea, its just that HP is directly related to rpm and torque is directly related to stroke and cc...
That will in fact reduce the life of your engine, but it might be fun while it lasts - just like my tobacco smoking.
It will be great fun for a short time. Had my xray scan of my lungs today - how fun is that really?
For cutting cookies at the you tube - by all means. But for milling - thats all a about the opposite.

Tried to pm you link. Hope the scan today went well.

Saws can be ported for milling as well. Milling saws would be ported differently than cookie cutters, obviously.

You clearly don’t own a properly ported saw, the way you’re carrying on. But that’s no reason to go about the path you’re taking in saying that ported saws won’t last and are only good for play.
 
Well, if the best and most payed scientists in the world came up with a chainsaw engine based on all the parameters we know - made it like that, why would they make it so bad compared to what you rednecks can achieve with a bottle of gin?

Classic.
I will continue to sit in my garage working on saws drinking my coffee while you are busy ****ing off

Im just saying; Husqvarna and Sthil have the best educated and most payed engine engineers hired in the world, and you just said that you just know so much better? Id say thats not really a wise attitude to the matter.
