Love the video. I have a MS660 I purchased new in 2009. I ordered the dual port muffler cover from Stihl and opened the stock port up more. I was told that it would gain .5 HP. I think it's important to scavenge all the heat you can from the engine for durability I also ordered the Australian high output control bolt and piston for the chain oiler. It keeps the 36" bar oiled nicely.
2nd time watching this one... Totally cringed both times when the nose of the bar came near the forklift, camera angle had me scared! Good job with consistency! You bogged it in almost exactly the same spot on both cuts! Lol
How long before the mtronic begins to adjust the mixture? One cut, or half a tank.? If you worked that saw for 30 minutes and then did the cut again, would it e faster as the mtronic has tuned it?
Because it has a fresh tune every time you start a 661. I own a 661 and a 660. On my second 661 and just clocked 600 hours, I still have a soft spot for the 660 being such honest saws.
die grinder with good set of burr bits would have made this easier. I did my echo CS-400 and it woke it up as well. Of course I did not have die grinder either when I did mine :).
I have a red eye 066 magnum that I used for milling and I could cut cookies off the end of a hard black maple that was 31" inside the bark, doing it in 45 seconds. I love that saw but now I have to work on the coil. My others are the 026 and the ms 260 pro.
The muffler mod won't hurt. I opened up the muffler and put the max flow on my 661. The m tronic will adjust quickly. These mods really wake the saw up.
Nicely done. What kind of wood is that?? What is the plan for the remainder of that log? Hopefully a kick ass chunk for a round coffee table, say about 6 inches thick or so...
It's an oak, we've a whole bunch of big oak logs right now. Were going to split it all into firewood, but with how much we have, and how hard it is to break down into manageable sizes, I believe a much larger tree outfit is slated to come in a few weeks with a semi-trailer mounted tub grinder and grind up/take everything we have in the lot right now. Boss said they're out of chips for mulch and asked if they could have it, hell yeah! lol Takes a large workload off of our shoulders. Need a piece? If you're in the St. Louis area I can get you some, just have to come pick it up is all.
I have a 661 and the Sthil master mechanic I bought it from said not to do a muffler mod. He explained that the computer module is designed to make adjustments to normal operating variances, temperature, altitude etc. but not able to add enough gas to keep it from running lean if a muffler mod is done. Was he BS'n me? Maybe, who knows. I did a muffler mod on my 362 but I have not run it that long yet to know for sure if it will run hot. I did buy an extra muffler to do the mod so if I needed to take it in during warranty period I could just switch the muffler back. But as far as the performance gain goes, it seems minimal with the exception of the noise. It sure sounds faster. Have you ever owned a Harley or a 69 SS396 Chevelle? I have and they were both loud which added to the experience. Is it the same thing? I think so a little. For now I think I'll leave the 661 stock and start foolin around with it after warranty. The performance gains on the bigger saws are not going to be as noticeable as the ones done on a small saw just because they are so strong already.
You're totally right in that I really just like the sound, and having fun fooling around with them. I've put quite a few tanks through all my mtronic saws, and they're all modded, and haven't had any issues yet. Other than they can be a bit tougher to start, often have to just hold them at full throttle.
Mike & Mariel Frost ehhhh... it’s throwing chips.... personally if it was skip chain it would be faster just because of the length of bar and diameter of wood... lots of chips loading up
I just bought a 661 for falling and bucking pine trees. Have you tried 404? wondering if its any different. Also heard an 8 sprocket can really help, any thoughts? Thanks great channel
Great video, i did the chain saws guys muffler mods on my ms 241 cm, ms 362 cm, ms 661 cm what a difference it made in power and throttle response i have not checked rpm yet to see what the gain is
Did you re-calibrate the m-tronic system after the mod? I didn't hear reference to doing it, wonder if there mid will have affected it, causing itmto need to be reset for further improvement in performance
Would you be able to make a video detailing how to tune the carb? I want to get a dual port muffler for my 044 but a lot of the youtube vids either use a tach or is someone giving limited detail and subjective descriptions of the process. If your chain sharpening and chain type vids are any indicator I think you would do a great job discussing tuning a saw carb.
Can do, can't really do it soon though, have a big new project I'm starting work on that is going to be taking quite a bit of my time. Will absolutely do it this winter though.
I just ordered a 661. I have a 170 and a 291. Do you think this type mod would give my 170 a little more? I primarily use it for bucking limbs and things but sometimes I cut something at the 14” max and wish it had just a little more balls on a new chain.
Yes it will. I did similar mod to my echo CS-400. You will have to tune the carb just a little bit richer though. Make sure you can adjust the high/low on it before you make the mod. I had to remove the limiter caps on my echo.
oh my god!!!!!!!!!!!!!!!! be careful!!!!!!!!!!!!!!!!!!!!!!!!!1you shouldn't have someone cutting right behind someone else!!!!!!!!!!! You did it twice in this video!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Nice video showing the process of getting rid of the EPA crap and the results, 4 seconds doesn't seem like a lot to some but you can tell the saw has more pull.
Hey so I just bought one used. It is extremely hard to pull the chord even when pressing the decompression button. Am I doing something wrong? Yours seemed to pull relatively smoothly. I'm thinking there might be something wrong with the decompression. I can get it to fire without a bar and drop starting it but even that is pretty hard.
Decomp valves are a known weak point on stihls, enough that many pros either plug it, or put in a husqvarna one. After pushing in the decomp, and pulling the rope slowly, can you hear air escaping from around the decomp? If not, that's likely your issue. If you can, then it might be a much larger problem with something binding in the drive train. Without a decomp, these can be quite the bear to pull start, does take a good bit of pull power.
First cut was 59 seconds and some change, post mod it was 55 and some change. Though it was actually slightly faster than even that as I let up a bit at the end to not hit asphalt.
being that us a 661-cm. how does the computer handle the changes? or does it even matter. I just picked one up the other day and would like to mod it but kinda scared I might ruin the engine on it.
I feel you, I have a brand new one in the garage, I'd love to mod it, but there's that computer thing, not to mention the warranty. I'm pretty sure that mod would void the warranty
Absolutely voids the warranty. From everything I've read the mods are handled by the computer very well. Not sure exactly how it effects it, but I've been running my mtronic 201T with muffler mod, and advanced timing for a couple months now and I've had no issues with it.
Not 100%, but from what I've read it actually runs cooler as it gets the hot exhaust gasses out of the muffler quicker. Don't have an answer for the longevity of the saw, but it's so common that I can't imagine it shortens its life, else it wouldn't be done so much.
I'd love to, buying new chains for these video's is really putting a hurt on my bank account though, lol. I've got a stack of only used once chains in my garage as is.
john reilly he used the same chain so it would only be duller after making the first cut and yet his modded muffler was still faster so I would say the test was not flawed
so 6.5% faster based on one cut. Not sure it really looks worth it. I did a dual port muffler on my 660 after seeing testing that showed it gave minimum 18% gains with 36" cuts.
😁 me too I'm just having trouble sticking with stihl these days I think Huskys small pro saws are better? but maybe Stihls big saws are good? haven't bought one.! What year is that 661 and how's it been for you.?
Southern Tas Climbers I'd love to get some husky's, just hard to justify as right now I don't actually need any more saws "can't believe I just said that, lol", also, as a former stihl salesman, I know their products pretty well and get a pretty decent discount on stihl products. The 661 is 2 or so months old, was brand new in the 661 review video. I love it, it's quite a bit more powerful than the 660 we use at work. With the muffler mod and an 8-tooth sprocket, it's a pretty fast cutting machine. Now just to get some more experience porting on cheaper saws, then doing the big guy =)
Great news about the 661 hope it keeps preforming for you.! cheers for letting everyone know about the 8 tooth sprocket too.! I will stay tuned Mate.! Jim
Why yes it is, and I hate it. Not because it's a not a great machine, but because our boss insists that the door not be removed, and with it on, you can only open it with the loader all the way down, really becomes an inconvenience. Of course I don't take it off when he's not around or anything, lol. Also it has a seatbelt, which really sucks when you're used to a lapbar on a bobcat which is 10x faster to engage. It's a new holland c232, I'll be making a video of it at a later date.
Yeah, keeps it from over reving. Though I did just rewatch the video, don't think it's that, would only hear that out of the cut and wide open. Not %100 sure to be honest, though after the mod the carb would need some cut time to adjust to the new running parameters, so it could be the carb adjusting.
Human Thank you. I didn't know that. I want to do this to my old 029 Super bit I never adjusted a carburetor before so I am a little worried I might fuck up and burn it out. The saw is like one of my kids.
Absolutely understandable. After a muffler mod, the saw will run lean, so you just have to back out the high side a bit. I'd hold off if you havent adjusted a carb before though. Maybe just grab a cheaper saw and play with it a bit. Back out the high side until it starts four stroking "count turns", and slowly bring it back to where it used to be while listening to how it runs at full throttle. Don't keep it full throttle long without a load though, not good for the saw, I usually just give it 1 second shots at full.
Go ELECTRIC......happier on your ears.....sadly I can't see you with a power cord strapped around your waist....at some of those humongous trees you go up.......Haha.....Joke Son!
Yeah, not doing anything more in depth for the time being. I've done enough mufflers to feel pretty comfortable with them though. By no means porting or anything like that, project for when I have more experience.
That sort of messing around mufflers is for competition saws only in my opinion. Where every second counts. 4 seconds better time is far too little to justify the noise coming out of her + I know it's two stroke only, but I think it still needs a bit of muffler pressure - I'd like to hear from someone who performed testing (stock, empty muffler), and can tell the difference in engine condition with and without mod.
If you're cutting all day, 4 seconds several times adds up. With the right ear protection and heavy use, the mod is justified. But for light duty, noise is more important. Nothing needs muffler pressure for longevity, so long as it is properly tuned. That said, 2 strokes will make more power with the appropriate resonance pipe - not a practical mod on chainsaws due to the space it takes up, better to just use a bigger engine.
The best mod you can do to the 661 is remove the junk m-tronic shit and install a carb off a 660 and a coil off a 660 then do the muffler mod and you will have a real saw that wont break down
Guys fucking around with their tools? It started when some asshole took his spear and decided to fab up another stick so he could throw it further. It will end when some asshole dials up his laser drill and gets everything banned, until then I'm of the opinion we let people mess up their tools however they please.

Resistance welds are stronger than the metal around them. That’s why the metals tears...
appreciate it and the saw sounds damn good man I do tree work my self to
Thanks, and yeah, the sound really gives me a chub, lol.
How long before the mtronic begins to adjust the mixture? One cut, or half a tank.?

661 seem to be a smoother saw than the 660, did not see it vibrate at all.
Because it has a fresh tune every time you start a 661. I own a 661 and a 660. On my second 661 and just clocked 600 hours, I still have a soft spot for the 660 being such honest saws.

Digging your music playlist in the background. Ha!
I dont know it might be just my imagination but the saw I've seen get the most from a muffler mod has got to be a ms290 its night and day

It would be possible to increase the air intake of the chainsaw so that it gains power?

nice video. keep up the great work.
I hate opening that muffler up. Every torque bolt feels like I'm gonna break it literally before it breaks loose.
Put some slits on the front of the muffler to make a dual port to get more power out of it.
Mmm.. To loose your warranty over a few seconds difference..... No thanks. 🤔😬😐
When doing for a living that we seconds per cut gets you home to your family quicker , so I agree
Just buy a performance muffler keep the stock terd and the saw needs to be warranted put the stock one on
@@shayn4220it makes it that much more fun as well I hate run a saw that lacks power but will cut nonstop if the saw is ripping it up

U high or something ?
Chainsaws are inherently dangerous maybe you should watch robins eating worms or your favorite osprey dine on a fresh caught trout
i did the same thing but i putted the gasket in the wrong position between the plate and the cylinder is it really that bad?
4 seconds a significant difference? Uh... no.. shorten the life of a $1400 saw for 4 seconds? Dumb
It extends the life of the saw. Heat is the number one killer of two stroke engines. The factory mufflers are so choked and build up heat.
Without the Muffler Mod Is about as fast as my Stihl 260 Pro took to go through a big hemlock
Do you have to tune the carb after a big muffler mod
What the fuck
I would not loctite them Bolts in the cylinder. That was pretty slick the way you drilled those welds out I like that
lol, wasn't really sure what else to do to break'em, damn resistance welds, lol

Decomp valves are a known weak point on stihls, enough that many pros either plug it, or put in a husqvarna one.

If you can, then it might be a much larger problem with something binding in the drive train.
Without a decomp, these can be quite the bear to pull start, does take a good bit of pull power.

Nice keep us updated on how this saw is
doesnt it run hotter? does it. cut chain saws life in half?
Not 100%, but from what I've read it actually runs cooler as it gets the hot exhaust gasses out of the muffler quicker. Don't have an answer for the longevity of the saw, but it's so common that I can't imagine it shortens its life, else it wouldn't be done so much.
maybe you should have started each cut with a brand new chain

IV got this saw and no muffler mod needed just run a 404 chain and it's a beast .
why do you run .404?
4 sec? Is it worth it? No! 50 such big cuts makes an improvment of 200sec = 3min and 20sec? And you dont make firewood from these big logs usually...
what's the song at 2:20 and

Hardly seems worth the bother for a 4% gain

try a sharp chain for better results
Why does the saw looks like it has a cut off ? mine just do bwaaaaa rather than bwawawawawa
Gotta find that happy middle ground, the bwaawaawaawaa!
Human 😂 but honestly do you know why ? ´cause Your little stihl saw does the same... Just wondering
The mtronics have rev limiters
to protect the saw ?
Yeah, keeps it from over reving. Though I did just rewatch the video, don't think it's that, would only hear that out of the cut and wide open. Not %100 sure to be honest, though after the mod the carb would need some cut time to adjust to the new running parameters, so it could be the carb adjusting.
Did you adjust the carb after the mod?
Nope, this is the mtronic version, so it adjusts itself. On others I mod, absolutely.
Human Thank you. I didn't know that. I want to do this to my old 029 Super bit I never adjusted a carburetor before so I am a little worried I might fuck up and burn it out. The saw is like one of my kids.
Absolutely understandable. After a muffler mod, the saw will run lean, so you just have to back out the high side a bit. I'd hold off if you havent adjusted a carb before though. Maybe just grab a cheaper saw and play with it a bit. Back out the high side until it starts four stroking "count turns", and slowly bring it back to where it used to be while listening to how it runs at full throttle. Don't keep it full throttle long without a load though, not good for the saw, I usually just give it 1 second shots at full.

That's impressive, but my 661C has zero cuts on it and I'd be terrified to bust it open and do a mod on it....lol
Yeah, not doing anything more in depth for the time being. I've done enough mufflers to feel pretty comfortable with them though. By no means porting or anything like that, project for when I have more experience.
hey you should port that beast
Oh my yes. Need to get some more experience porting before taking that job on though. It'd be costly should I screw it up.
Human yeah definitely wouldn't want to screw that saw up
Cut all day , then watch you!

4 seconds better time is far too little to justify the noise coming out of her + I know it's two stroke only, but I think it still needs a bit of muffler pressure - I'd like to hear from someone who performed testing (stock, empty muffler), and can tell the difference in engine condition with and without mod.
If you're cutting all day, 4 seconds several times adds up. With the right ear protection and heavy use, the mod is justified. But for light duty, noise is more important.
Nothing needs muffler pressure for longevity, so long as it is properly tuned. That said, 2 strokes will make more power with the appropriate resonance pipe - not a practical mod on chainsaws due to the space it takes up, better to just use a bigger engine.
The best mod you can do to the 661 is remove the junk m-tronic shit and install a carb off a 660 and a coil off a 660 then do the muffler mod and you will have a real saw that wont break down
I can tell your old school as hell, ive had zero issues with mtronic, or husky autotune, but then again I look after my saws well
I'm professional timber feller. I have a 661 i have been running for 8-9 Months straight and haven't had 1 hiccup or problem.
Brent Wonsyld for now.
Unless you are a timber faller I wouldn't touch the muffler.
The amount of power gained doesn't justify the noise.
Dan Henderson well said, for the amount of time and effort and then the subsequent noise, all for a few seconds cutting is not worth it.
Guys fucking around with their tools? It started when some asshole took his spear and decided to fab up another stick so he could throw it further. It will end when some asshole dials up his laser drill and gets everything banned, until then I'm of the opinion we let people mess up their tools however they please.
Yeah but what’s the extra noise matter? should be wearing heating protection anyway?
Bullshit , no way to for certain determine it is due to the muffler mod …!
