Husqvarna 3120 - Modified Exhaust

- A 'Modified Chainsaws' group member shipped this to me from California. I mounted it up to my saw and took it for a rip. Now it will be sent to another group member in another part of the world.

The upper cover is used to cool the cylinder from the fan. Without it, the cylinder does not cool!
I have been running a craftsman hedge trimmer with straight pipes, for almost 6 seasons now, never even had to tune or put a new plug in it yet. But then again I own (straight pipe, straight cut ) lawn care.
You might want to look into expansion chambers! As any 2-stroke racer knows.
Couldn't agree more.
you should definitely put the plastic on top because it can not get cold
Looks and sounds fun but not adding any HP. The idea of a two stroke exhaust is to reflect a sound wave back at the right time to keep the fresh air, fuel and oil charge in the cylinder that came up the transfers from the crankcase. This pipe actually converges and gets bigger... you would likely have to run the saw with the high speed screw backed out a lot more than with a stock can type exhaust. It is what it is take it or leave it.
This saw was running rich. This exhaust would have reduced backpressure or even created a vacuum. For peak power this is an advantage in chainsaws. More fuel would be required as you say and this guy has clearly added fuel, possibly too much. I expect he gained some top end power with this pipe. Stock 3120's are pretty detuned stock, they need to be ported to get them going. 395 is a better saw for pretty much everything. You can play around with mufflers but if you want a saw to go you need to port them.
Would have been nice if you posted your thoughts on any power changes it made to the saw.
that sounds badass
Yes it does 😋💨💗
Well, that is a new one...😳 The sound is nice, but power...?🤔

the guy that made it didnt make a full cut with it at the log show i was at with him. this is not only bubblegum welded but also didnt work for shit on his own saw. shipping it across the world to fail again is priceless---lol
Mmm that chainsaw is very good and beautiful
Looks like Helen Keller got ahold of a welder
Stereo sound on a muffler, now you can blow both eardrums simultaneously.

It’s a 2 stroke it needs a tuned pipe
Not good to run them saws with out the full air cover on it
Its okay only if you adjust the jet or air/fuel mixture.
No the cover is part of how the flywheel pushes air over the jug and cools the saw down
@@jiveturkey231 yeah that is true! The fan shroud directs air over the fins. But I think (guessing) he only ran it briefly - vs running saw all day. As the fuel goes through it does cool the cylinder a lot. That exhaust may sound nice but it could be bad. need some backpressure on two stroke. Megaphone exhaust help pull the air fuel charges out of the crankcase and into the cylinder. However It "may" be causing too big of a vacuum and sucking the fuel out of the cylinderas well. Its definitely fun to have a loud two-stroke regardless of the performance and "numbers". As long as they are having fun and not causing the modifications to melt anything then it's a great time!
How to piss people off with a loud un-muffled sound, to the LEFT and the RIGHT!
He needs an expansion chamber to scavenge and increase velocity. I'm no expert but just my worthless opinion.
Not really worthless when you're right
@@rannz8 thank you jimmy I appreciate that.
2-stroke engines need something like an expansion chamber to efficiently work. No exhaust, which works similar, the unit cannot reach its destinated power output.
These pipes drastically increase power of course there not cpi pipes but way better than stock mufflers
Damn that's a hot saw
You lost power with this exhaust
Thanks now I don't have to break the news
Looks and sounds cool but I think you should try a smaller pipe
if the homemade pot is made of iron the skillet will save heat
There is power ;-)
Love this freakin pipe what’s the measurements on it
You lost the chain brakes but you gained a couple more horsepower
Bad deal
Lost chain brake and horsepower
I would love to order one of these! 😍 wonder if its possible to make one for a 359xp
140 psi Good compresion 372xp oem?
Why post this question everywhere?
very good....👍
That exhaust will ruin your engine. Back pressure on 2 strokes is very important. You lost your cooling effect with that open pipe on there. It will hopefully ruin the reeds before you ruin the engine. Take that exhaust and throw if far away from you.. unless you put silencer on the saw
I was planning on welding a custom exhaust for my chainsaw engine, only because I'm using the engine to make a custom scooter. Is there a way to make an exhaust that won't damage the engine?
How did you recreate the expansion chamber? Two strokes are pretty anemic without them
Also two strokes are more sensitive to having proper back pressure for more complete combustion.
Good👍👍
that saws going to over heat with out the cover
Does whoever built that exhaust have a website or some kind of contact info? I’ve been looking for something just like that for my 3120...
veľmi divný zvuk, neviem výhody toho výfuku bolo to ako motorka ,,, ja mám 15 píl najmenšia H 136 ak nerátam Mac 130 tie mám dve starenky H 266 a moja špica je H 385 a pod tým iné chrliaky i jonsered Dolpinu a Zid Tajga ..
Поршневой с такой трубой хватит не на долго...)
Wat ever u did to that saw,it aint helpin it at all,looks nd sounds like it killin ur power,but wat do i know,only ben runnin them nd fixin them for 50 yrs😉🤣
Looks like something i made for a poulan i had. Itll burn the motor out fast.
Never mind about the thong sorry. Nice saw
👍
Eu não sei a husqvarna já tá no mercado a uns 300 anos e vem um qualquer e que modificar a motosserra .
Какова мораль этого видео?
Maybe seems weaker than original ...
Looks hot but it's not. I have a stock Husky 2100CD with a 36 inch bar that would wipe that saw head to head.
His rakers are too high or the saw is dull. He is forced to used the bumper spikes to push the saw blade into the wood. A sharp properly filed saw with the rakers at the right level will pull itself through the cut effortlessly. This guy is working his saw when the saw should be doing all of the work while he just holds on.
Panbubak is right. That saw will burn out without the upper cover. This saw is not a motorcycle. It has to create it's own wind. This man is not a pro. He is just having fun.
Thank you for blessing us with your wisdom big man.

30 years as a pro and in competitions. I have seen it all. If you adjusted the rakers properly and filed it really sharp your saw would cut like this one.

You’re right. A bar and chain bolted to a V8, cutting through dry poplar is the exact same as a 3120 pulling full compliment in solid red oak. I’m very impressed by your pro designation. Do you have a link to a video of your own that you can share?

I set the camera at the wrong angle. I was cutting several 16 inch Rock Maple logs on 8ft. forks with a 36" bar. The 36" was fully engaged. If the camera were set to the side, the cutting would have been more impressive. Rock Maple is so hard that you have to file the saw different with high rakers or the saw will bounce around or bog down.
When you work in the woods with mixed timber, you have to bring two saws. One is filed for Rock Maple and the other for all other woods.
Carby sounds a little rich
Little lean on the top end its breaking up
Actually its rich. A lean 2 stroke does not 4 stroke at all. Peak power drops off, heat builds and they lean out more a generate more heat till it self destructs in a worse case scenario.
Bon dimanche au voisinage 🤣
Sounds like it’s four strokin
Голимый Китайский Штиль но показатели на высоте!
Oil mix ?
I was expecting a cleaning cut
Is like a mosquito sound
no!!!!!
Parece q tá se peidando pra corta q viajem kkkkkkkk
Worst chainsaw sound. Number1!
Am I seeing things or was this dude wearing a thong?
0:45 ¿Tanga????
Just belt
terrible workmanship on exhaust looks like shit
Parece q esta cortando giro 😂😂
Хусквар всегда плохо заводится!
Ugly and absolutly no function. I think my 395 would cut faster. Too bad i watched this all the way and actually helped the analytics of this channel.
Sounds like shit goes like shit
power up ？
Probably gave less "power" than stock muffler. Need proper tuned expansion chamber for performance gains.
Ха-ха, у Меня китайская запускается со второго раза! 😅
No one wants an aerial shot of you cutting wood with a modded chainsaw a exhaust. It's loud but that doesn't mean it sounds good. Like others have said you beating the shit out of that thing for no reason
Ghetto muffler
Mosquito...
Motocross
Mmmmmm
wtf XDDDDDD
You lost power with this exhaust ..
👍
