Not yet, lol. I try not to run them too late or too early. I also try to befriend them and help them out every now and then with odds and ends. And I tell them it's a peace offering for putting up with the saws

Thats cool. I'm sure the fence helps too, I just noticed all the chips in your yard and thought you must be doing alot of cutting.
That's been collecting all winter. It's been too wet to burn
You read my mind on that Brad!!!!
I made a slug to mode mine a few weeks ago just for the same thing...Now I have grind it into shape,,and split it into for 2 pieces for each side,,but this is the ruff slug I had made so far....Thats one thing I dont like about the factory exhaust,,,burns the paint off the clutch cover and the heat burns your hands on the handle bar.....
The muffler mod is done. I extended the factory deflector, so as to keep the finish on the case and clutch cover from burning and turning black. I then blended the factory deflector under the new one so that it has a nice smooth transition. I also significantly opened up the port underneath, more than you could without extending the deflector. I tuned the saw to 13,000, where it is still considerably rich. I'll probably leave it there for a tank or two. These cuts are the first since the single cut I made with it last night. Yes, I'm babying this one a little

I was wondering about the neighbors too. I'm glad my neighbors aren't that close. I think my neighbor goes into heat when he hears a saw start
Lol!!!
Where I live I dont have to worry about neighbors,,but still it's so quiet you can fart and someone a mile a way can hear it....LOL!!! If I lived next door to someone they would have already called the noise police with my Mcc's....

Doesn't sound rich to me mang. . . Cleans right up in the cut.
I expect it to turn 14,000 once I lean it out a little more. With a stock muffler, spec is 13,500. I'll wait a couple tanks to do that though.
I just checked squish and compression, .024" and just shy of 150 PSI. The plan is to put a popup in it and set squish about .018".

yep
Why 14K? It sounds plenty happy at 13k to me. 4 strokes and cleans up...what's not to love??
No fears. It'll be turning 15,500-16,500 soon enough
Stipes is a blubbering pig at 15,000!

Is Nik still turning your pop-ups for you?
That squish is fairly tight already. . . A guy would expect taller on a 440 or 066, but that 066 I just did was .024" as well with factory gasket. .018" should bump that saw up nicely.
14,000 sounds about right. . . I've seen a 500-800 rpm gain from muffler mods as kind'a an average.

Yes he is. BTW, I've seen .017" with a gasket on my 066. I've had no problems with it. So I have no concerns at all with .018" on a 440.
I know Brad....
I was so suprised how much it was 4 strokin and out of the box!!! I'll let you lean it up at the next GTG,,and dont cheat!!! LOL!!!!

WOW! Dang, they really got that 066 close?
You've set a bunch of you saws' at .018" IIRC. . . I didn't think you'd have an issue.

My 660 won't even turn over with the gasket out..

I also noticed the exhaust port was already pretty wide on the 66 I had apart. . . Good on Stihl for that one. Not to say I didn't improve on that wideness thing. LOL
