And you guys call me a troll.
Hey, don't sweat it A muffler mod goes a LONG way on a MS390. Porting should help just like any saw. It's just harder to get down inside the jug to the ports. You're right on increasing compression. Welding a popup is about the only feasible means. I would try just porting it first. That and a muffler mod will get you what you're looking for.Look guys I let a couple comments get to me, I owe Brad especially a apology I am sorry man you have helped me when no one on here would, next time I will stop and think about what you have to say before I respond.
As for this bar thing there is what works on papper and what works for me, I honestly bought the saws this way like it or not it works, and works well, maybe it shouldn't I don't argue that, but it does work. I like it let it be, I believe that the 3/8 .050 skip tooth helps, I am also telling you this thing has some nut.
O.K. Clamshell design(now we are getting some where) so we are looking at something similar to the PM610 by Mac or Poulans new saws, where the only way to raise compression would be with a pop up piston. That means I need to find a good wielder and machinist. Perhaps mild porting would be the way to start. I retuned the carb and was amazed, apparently they tuned it to 11500, I brought it up to 12500, I think I can raise it more but would like to wait until I break it in more, but it wants more.
Forgiven!!! Trust me...I've been there
I do believe the dealer put a 28" bar on so that it would "sell faster."
As crazy as this sounds, my local Husky dealer says that many times he puts longer bars on because folks "like the looks of a big bar" on a saw.
exactly,why do you think poulan slapps 18's on the wild thang. its not to much bar till someone sticks it in an 18"log,it sucks. but put 16" and keep your wood under 14" muff mod it tuneit and shes on fire.
you can run a 28" on your 390, but bury it in a 26-28" hardwood it will stumble,pine maybe not. but keep your wood about 20" it should work good.
people for some reason thinks its the bar that dictates wood size ,and them complain the loudest. dealers(some) make their living of the "size" card.
also automotive motors are not the same animals as saw motors,very poor comparision ,and holds no marit.
you do also realize as soon as you mod your saw the warranty is worthless.

By the way I am no idiot I am comparing a 64.1 cc saw to a 72 cc saw that's a difference of 8cc it ain't that big a jump, I have seen small block chevys eat big blocks, where the displacement was a lot larger. Problem as I see it is you don't want to admit you got screwed out of money for a over priced saw, when you could have bought something else, and got better performance. Don't presume I am stupid I did my home work, I don't like following everyone elses lead. All I wanted was to see If someone had had the courage to try something new, I am pretty disappointed.
Here are a few pic's from left to right ; My ever faithful 034(wish my dog acted like this saw) next up my 2100cd woods ported(I pull pipe back for a living on drilling rigs I can't stall this thing awesome power) Last the new guy MS 391 and yes that is the contirversal 28" bar. That little load of wood in the back is fully aged pinion, so full of pitch that it won't split with a axe, and a splitter pretty much just crushes it. It was all cut and saw split with that MS 391 and a 28" bar. Guess the proof is right there this saw works and works well, I don't regret laying down 6 bills for it, I just regret that I am going to have to head back to the rig before I can enjoy it more. I am slowly becoming a Stihl fan just please don't let the husky guys know
the ms391 looks pretty good with a 28" bar. also it is the first time I have noticed the differences in the look compared to the ms390
It looks like the MS362.
Sure does, handled (fondled) the 391 a bit today...
this was the quote i was referencing. small blocks can be better than big blocks,put a 327/350hp angainst a 70's 460bb ,yes the sb will smoke a bb.but here you say 8cc isnt a big jump but your comparing cc to hundreds of ci in difference.
do some simple math and convert a 64cc to a motor size equivilent then find what the difference 8cc would be.youll be surprised how much bigger it really is.
