Put the Egan's straight shot on my 400 ,but was just to loud. Would make your head vibrate. So I welded a grade 8 washer in the hole and closed up half the size hole. Still very loud.
You need to start the saw to set the m tronic on choke warm up position for at least 30 seconds, then run it full throttle until the motor spudders down, turn it off, the m tronic is set. The Bark Box should help the 400 out in torque in deep cuts I notice on my 400c. The 400 is a hyper active rpm saw, but sometimes in bigger wood it just stops dead and loses power easy, but the Bark Box should help keep the torgue curve in the cut and powers thru the sticking point in the wood.
I am not sure people know that if you change mufflers or a big change in altitude and the saw is running rough time to time, you have to recalibrate the m tronic system. It has been a while when I did mine, but when the saw is cold, leave it on the bottom burp position with the chain break on for over 30 seconds when it starts, take the chain break off, then just give it full throttle gas, the saw will run funky for a few seconds then it will whine out until it spudders, turn it off, that is how the m tronic recalibrates its self, if you don't hear the spudders at the end of the sequence, the saw didn't recalibrate. I think because the saw is running cooler with the different air gas mixture the saw has to be completely recalibrated to program to run efficiently, you notice a monster difference in your saw. Sorry, I am just trying to help out anybody has the third generation m tronic on their stihl saws and if your saw is running funky you might have to reprogram the m tronic system, thanks take care...@@oakeymt.outdoors
A sharp chain will take care of all that,any saw would get stuck on big timber if one only throws sawdust n overworking the saw ! I'll cut 20inch hard logs with a 251c Stihl 😊 factory standard, no porting B S !!!
@@gunterbecker8528yes,sharp chains do wonders,but so do ported mufflers. They're just $75 and do help with torque,horsepower and heat dispersal. I've got a stock ms250 that I love,its a great little saw,but if I'm bucking up 20"+ oak I'd rather reach for a bigger more capable saw. My ms250 can and has done it,but it can be done more efficiently with an ms400,with a bark box😊
@@oakeymt.outdoors either one will be good for you . I'm on the Pacific Northwest coast of the united states . We get a lot of Doug fir , western hemlock , Oregon Ash , red Alder and Oregon White Oak . But in certain counties the oak is protected .
I couldn't tell for sure but are you running a skip tooth chain? If not please go try it. My 400 has enough power for it and it throws curls off pretty big. Cuts just as good as my buddies 661
I've got the 400 with the bark box from WCS. I skipped ahead, so you may have stated why... but My 400 goes through rounds of Australian hardwood here on my farm far quicker than what your saw is getting through that log.
Man I’ve wanted one of those new 400’s but you can’t find them here in the southeast! I’ve been to 4 closest stihl dealers and they’ve never even seen one yet in the almost 2 years they’ve been out. They’re more scarce than the 500i was.
I've found them used on ebay for $799,but it's a roll of the dice. I just found one that looked like itd been hardly used for sale locally for $690 with a 25" bar and chain. I dont mind used as long as I can check it out good before buyin.
Could someone tell me exactly the size of the Bark box outlet (excluding the filling of the spark arrestor, so just the free space opening), so I can make something myself, since we don't have them available in Holland? Thank you!
@@oakeymt.outdoors and must the iron mesh of the spark arrestor be subtracted from this to get the net outlet hole size of the bark box? And if I understand correctly, the bark box exhaust hole is an extra hole next to the factory outlet, right? Thank you for responding, that will help me a lot to improve my 400!
@@wilfreyvanderlinden9595 it looks like the hole with the spark arrestor is the exact same size as the exhaust port on the saw. The outlet hole is right beside the factory hole that stays when you put the bark box on.
@@oakeymt.outdoors I am sorry I wasn’t clear enough to you, but I mean how much space will the spark arrestor take from the 1”x3/4” outlet space, and how much space will be left from the outlet space (when you have substracted the mesh content of the spark arrestor)? Or is the mesh from the spark arrestor so less That it doesn’t have an effect
The bark box messes up the design of the oem expansion chamber by basically cutting it in half, and w a flat side opposite the cylinder. Ruining its volumetric efficiency. Imo.
@@ciphercode2298 You probably think louder means more performance. Do you understand how 2 stroke engines work? Do you see comp saws with Bark boxes or dirt bike expansion chambers? lmao
@@Jaun2Three there are numerous videos showing dynamometer results confirming the difference. Theres also cut time comparisons videos. The cooling effect it has on the engine alone is enough reason to do it. Heat is the killer of little 2 stroke engines. As to whether or not it messes up its volumetric efficiency, I'd say it seems to work just fine and has no detrimental effects on its performance or economy.
@ciphercode2298 Hey, I bought one, It's a solid piece and looks good. But you can't compare the bb and a stock muffler w the screen out, or screen out and a drill hole. If you open the stock muffler cutting all the spark arrester mount out and smooth the inside all out. And you open it up to the same dimension as the bb exit. Then it'd be a fair comparison and you'd see the extra volume in the oem muffler compared to the design of the bb that puts a flat face instead of everything rounded.
who knew after 35 years of operating 2 stroke engines that I was doing it wrong the whole time? I better get out there and practice blapping the throttle incessantly 🙄
Stihl and other manufacturers have decreased the outlets on mufflers and have added baffles to satisfy government standards over the years. It restricts airflow and decreases power and efficiency. It also holds in alot of heat. Bark boxes are made by a reputable company on America's west coast out of heavier gauge stainless steel than what comes from stihl. They provide better airflow,increases in power and efficiency, and reduce heat in the engine. It's not some homemade crap,as you so ignorantly put it,but you're welcome to your opinion, I guess.
Better watch these rip off bark boxes,they tend to fall apart from low quality build. Your far better off buying fom EGAn Performance who orginally came up with the bark box and builds a far superior product. Bark boxes are all right but it is better to put a good chain on them and learn to sharpen the chain. t
I like how Stihl has their muffler setup. Pretty cool. The box looks super nice. Curious to see if there is improvement!
It made a big difference. Wondering now if I need to put that Red Beard filter on it
@@oakeymt.outdoors the Stihl filter seem restricted or maybe insufficient?

Cool, though what I learned is you have to reset your mtronics after installing the bark box. It’s very easy There’s videos on how to do it
