Husqvarna 390xp vs. 395xp Bench Talk

- Hear we are in the shop,,, for a little talk.... On the bench today, boys and girls, we have a little comparison overview between the Husqvarna 390xp and it's big bro, the 395xp. I have been looking at the internal workings of both these saws for years, and, in all honesty, never really thought about shooting a comparison and contrast video - sorry it took soooo long.
Both these saws are from the same gentlemen. As stated, I did another insane-o saw project a few weeks back for him. Seems that he was well pleased enough to send me a couple more.
In the actual saw off video of these two, the 390xp only ran 2/3 seconds slower. With giving up almost 6cc of displacement, the little saw that could, did, and it did really well.
For all the hyper critics, yes, yes I did blunder the part talking about when the intake boot (manifold) changed for the 2 series to the 3 series Husqvarna. I am, admittedly,,, only human.
I am currently available for port work. I you are interested, please shoot me an email.

Thanks for watching.
I like this guys attitude
So many good tidbits of info regarding the motorcycle style piston/case and parasitic drag, and the history/evolution of the 395. It was good to see the comparisons of ports and such too. Thanks for sharing ,Jack, and those are mighty clean saws.
awesome vid love to hear shop talk from a pro
I use Mobile One high mileage engine oil. You might think I'm crazy, but it keeps everything clean, and there's always a coat of oil on everything inside. It doesn't carbon everything up, but the exhaust stays dry. I've never hurt a saw with this mix. I run 40 to 1.
Very interesting Mr. Timothy. You are the second person since the 1980's I have heard confess this practice.
@@Brian2bears Works.
@@timothybyrom5560 I have two great-uncles who ran Mobile 1 in taxi cabs before the high-mileage formula. They changed filters and added oil, no change, for the life of the car.
@@Brian2bears I run Rottela in all my rigs. I have a 1990 ranger with over 600000 miles on it. Don't use a drop of oil.
Ran the 394 for a few years, and it's a beast of a saw. Very reliable.
Yeah buddy, thanks for sharing Mr Jack
great shop talk Jack. glad to see your staying busy
U definitely do great work sir!!
One tip i was given when i kept fouling plugs in my dirtbike. Running a little higher octane fuel will help to burn out the oil. I went from changing plugs every 3 tanks to running one plug for over a year.
Kyle hi.
Bikes usually have higher compression ratios than saws. That alone should be helpful with the added heat provided that the jetting is "on"
Part of that could the mix oil concentration. I only remember fowling one plug in my bike and it was a day that I was putzn around doing "traveling" on logging roads. I have never fowled a plug in a saw. It could be that I run the factory recommended ~ the 2% concentration level for saws. I ran the same in bikes well. I have used good to awesome mix oil for my entire felling career. Pump gas to 117 octane race fuel also. Around 98/100 seems to work pretty good in saws and doesn't cost an arm & a leg when you are burning through 1.5/2 gallons a day.
Part of it could be the mix oil choice. They are not all created equally, not even close.
Using a par type oil with improper jetting can net you the same result - a fowled plug.
Anyhoo, glad at least part of the problem is now rectified.
Thanks for watching.
Happy veterans day sir.
“It’s a lot easier to screw it up than to get it right”... That’s Golden!
I love my 395 and won’t be opening it up until there’s a true ‘need’ to do so. I see a lot of guys on CZcams making mods that sometimes seem to lack any science to what they’re doing. There are however a few of you that lend confidence as they speak. Bless’ns to ya, Tedd
Nice one,carry on with this kind of videos !
Have really enjoyed your fallin' vids the last several years, but this new addition of the occasional shop vid is great too! I switched from the Husky oil (all Husky saws) to the newest version of the Stihl oil, understanding it to be the best around. Sounds like I have more to learn about quality 2-stroke oils! Thanks for taking the time to film and post the vids you do! ATB!
The ultra is pretty good, but not the best around imho. I am currently in the process of getting my ducks in a row for my interpretation of the what and why on the mix oil front,
Thanks for watching.
I look forward to what you come up with!
This guy has got it together...
Great vid very informative
great video
My 266 broke down today so I ran out an snagged up a 390. So far great!
did enjoy it , very informative and factual with no bullshit. that what i like.
awesome video
Thanks for your video. I’m thinking on a 390xp, but not sure. I need something for cutting the big oaks. Had some to fall from wind. God bless.
DirtBleep hi. The 390 is not a bad platform. There are a few factors to consider. Bar mounts already in a guys collection and dealer support in your area would be a couple. Good luck with the extraction process!
Thanks for taking the time to share your views. Love your stuff William Jay Crooks. You seem familiar to me? Have you ever worked in Minnesota. Wisconsin or in the Upper Peninsula of Michigan?
Dear Sir: been watching your stuff for a while and it’s helped to inspire me (along with Dan Kain of Kain Kustom Garage) to rehab classic Huskies. Right now I’m working on a first or second Gen 288xp with metal brake bar and also a rare 77’ 380CD which ironically is a 77’ manufactured date. My question is what’s your advice on restoring the mechanical parts as far as applying any finishes to things like the jug or muffler? I’m not suggesting necessarily painting parts like cylinders but do you do anything in particular to make it presentable aside from internal honing or just exterior cleaning? Thanks. Dan
Great video along with ALL your others. It is very cool to see what you do to the saws and the commentary to go along with them . I enjoy "tweeking" with my saws and would love to send you one someday. Which saw do you feel you can "squeeze" the most out of? I took my old 371xp and put a Stihl 064 piston in a big bore jug that a mildly ported (nothing calculated) along with a 390xp intake and carburetor. I'd love to have cut the squish and domed the piston, compression ended up a little low. I think with a bump to about 185 psi and itd be a screamer.
Keep the videos coming ....I think you have plenty of people that enjoy the heck out of them!
Nice video never been into a 395 never could stand husky oil had to fix a couple of saws for people with stuck rings and gives me headaches. I've been really happy with red armor haven't seen motul locally.
rolling shutter alarm !
Jack... I can't thank you enough, brother (Ohhh... this is Jed, not Kristen) it's just always such a treat to get to look into a saw through the eyes of a professional, rather than through those of an aborist-hack (namely: myself) whose messed-up far more saws than he's ever helped.
Thanks so much for doing what you do, Jack. Can't WAIT fer the day when I can afford (I do have some new evidence that it won't be long now) to send ya a brand-new 395 to tweak to perfection. Or maybe a 372, I can't decide.
Interesting vid but 288xp all the way for me.
Very cool. Got a 390xp on order. Is it worth insaneo-ing a 2010 rancher 455? She owes me nothin, love it for smaller forest work but was like bringing a knife to a gunfight on some of the tree service rock maples. Awesome vids keep em comin
excellent video! what do you think of the 272xp saws?
Properly done, they will pull a 32" bar nicely.
Thanks for watching.
After I get my 390 xp. I'm going to send it to you and see if i can get the insane-o ss on it plus a better muffler
Very informative video!
What type o Motul 2 stroke oil are you using and in what percentage?
Motul 800?
Either version of the 800 2T.
Thanks!
And how much should i put?
40:1, 50:1?
50:1
How do you feel about amsoil 100:1 ? I've used it for 30 years and have never had a problem once... I run it in everything and love it, I notice a real difference with it...
docrw hi. Way to lean for me. There is a noticeable loss of low end going to just 60:1. Sure they do rev up quick, but that's not what I'm interested in necessarily.
Thanks for watching.
i can't even imagine all the trial and error you've done over the years to perfect your hop ups. always enjoy your videos jack. are you back in eastern Oregon again?
But they couldn't prevent Jack from being happy la la la !
I like all your Snap on tolls lying around the bench. lol.Are those vertical lines on that last piston from bad porting or leaning out from fuel mix?
It appeared to me that the attempt to alter the intake port yielded the "fancy" piston skirt. You do get what you pay for....
Thanks for watching.
@@hotsaws101 Friend, if the saw 372 xp after replacing the OEM piston, the compression will increase? after a few tanks now it is only 140 psi after refurbishment
@@Sensei948 That may happen. Depends upon a few factors & operator input.
With the EPA version slug (duel rings) the 372s are ~ 150 psi. 140 psi with a single ring piston seems reasonable. But that is also dictated by a few factors.
It is impossible for me to tell much about a saw that I did not run, tear down
& inspect, or assemble.
I'd run the thing for a bit before getting too concerned. This of course is based on the idea that the installation process was done correctly.
Thanks for watching.
@@hotsaws101 Friend, how to use the saw after renovation? What is the best maximum speed for 372 xp oe?
Nice job!!!!!😎😎😎😎
Great video. Have you ever run amsoil interceptor oil? I have been running it as I've always liked it in my sled, just wondering what your opinion is on it
Josh hi. Never really been a fan. I would be using the Maxima Formula K2 as my 1st choice. Maybe the HR-1 if it's a little older with a bunch of time on it.
Thanks for watching.
What is your opion on the Husky 385, I like it pretty well ,feels alot lighter then a 372.
Scott hi.
The 385 & 390 are the same basic platform. At least 1½ pounds more mass than a 372 - any version of them.
You must be a lot stronger than giving yourself credit.
Thanks for watching.
I had no idea there was that much difference between those saws cool to see side by side everyone that watches CZcams thinks thay can port nowadays but I know without working side by side with someone like you that has did the r&d it's not easy I am looking to up grade my milling saw I got a stihl 070 running 8t on a 36 running 8,500 I have a carriage and rails like a band mill so weight is not a issue what saw would you recommend as a better option has to be a good oiler any help would be appreciated
Tom hi. That seems to be true.
I think that for ripping the chain better be excellent. I'm not sure why with that short of bar your having oiler issues. Thinking out loud.... Maybe the oiler is worn and/or gear and not working properly. Tank screen might be plugged, partially plugged. The oil line might be perforated. The oiler seal might be hard a the system is sucking air. I'd check those first.
You never said how much time is on you saw. Milling is like a dyno run for saws. Parts "take a licking, some quit tickin" much earlier than standard saw type work.
Good luck.
sweet!!!
576 husky? 390 husky? 395 husky? power? cost? I cut 30" plus quality red oak 2-3 months out of the year. been satisfied with 372 husky but bigger saw produce more daily.
Flat ground, yarder block? Green, cured? Dirty, clean? Milling, falling?
Hard to answer the ?s without more info.
Thanks for watching.
flat ground. pole skidding once in a while short wood skidding. i guess i am looking for overall speed of cut. pure wood production.
Insane-O-ized 395xp sporting a 33" bar & chain and the mini hardwood dawgs fitted.
Blessing for this day.
hotsaws101 thank you sir will take into consideration.
hello. have you don't any work on a Husqvarna 353 (e-tech). kinda wondering if I can get more out of.
Hello. I can get more out of it.
Thanks for watching.
What two stroke oil do you use? Maxima k2? Maxima super m? Or maxima 927? I don’t think the new Husqvarna pre mix 50:1 is good enough.
Bill hi.
None of the above. I blend my own. Husky did reformulate from the old version. The new version is far superior to it's predecessor. I do agree with your assessment that either option is not a good choice though.
Thanks for watching.
140 psi is good compression for 372xp 2003?
Did you finish the stihl ms362 cm build? I'm interested in a video of ur work of it.
Mr. Saw Professor, I have 3 562's, 2 went out of commission within their first year of normal daily logging operation. Both still runs but bearing(s) shift on them to put the clutch in motion on idle or jamming the clutch killing the motor on idle. Could this due to the mix oil? I'm hesitant to buy another one due to these problems. I can't handle heavier saws working all day because I cut tiny trees in Wisconsin. But this past week I cut some pines that were 30"-40" in diameter with the old faithful 357's.
Donny Sath hi. This post slipped through the cracks - sorry. If your bearings are wearing out prematurely then the mix oil could be the issue. Running dirty air through the engine will wear moving parts out quicker as well. I've seen where those saws pass particulates through the filters. Depending on what the grit factor is, that could also be the problem. Or it a combo of the two. Heard if a few instances where the crank cases were mismanufactored and outer races shifted in the race wells - highly uncommon though.
Thanks for watching.
I'm confused, how does cutting material out of the combustion chamber reduce its volume? I'm sure I'm missing something... 🤷♂️
toadamine hi.
It reduces the total volume by taking away from overall footprint of the combustion chamber.
I.E, saw a bowl in 1/2 and you cannot put the same amount of Cheerios in it.
Thanks for watching.
@@hotsaws101 doesn't the piston still only come up to the old height though? Doesn't that just make the bowl wider?
@@toadaminecutting the squish band makes the combustion chamber smaller but also makes your squish looser so after you have machined the chamber smaller you go and cut the cylinder base on a lathe to get your preferred amount of squish clearance.
can you port my 044? please!
do you get more torque out of the 395 than the 2100's then?
madreamer hi. All thing being equal, I think the 2100/2101 can be made to have more down low. Trouble is find one in good enough shape to zipp and have live.
Thanks for watching.
Хускварна 395хр пилка "огонь".Як робе на холостих,вуха отримують оргазм
Love love love it. What do you prefer the 390 or 395? I tent to like the slimmer design a bit more but that just me
Bar length dictates that for me personally. I tested the prototype 38? (385) in 01'/02'. Made some suggestion to engineering. The production saws still came wide, among other things.
Thanks for watching.
What oil do you recommend for stihl?
I run either Maxima or Motul
Cool beans 😎Jack ..... the drone is hovering over the Shop right now trying to glean info haha
Do you have an opinion on Klotz 50:1?
WVStrokerSmoker hi. Which version of their oil are you talking about?
Thanks for watching.
hotsaws101 Techniplate I believe. Says 50:1 on the bottle. It's not castor..
I have not run this oil in 15 years and do not even know if it is the same formulation as back then - but think it is not. I do know that Klotz revised (down) the printed data on some of values for this oil in the last month, month and a half. How long before that did the product change happen is sketchy.
Thanks for watching.
You offer quotes?
Jakob Hanson Hello. My email address is in the description. It's the best way to contact me. Thanks for watching.
So what can you do to a stock Brand New 395xp? Wanna do a video? Just purchased my 395 XP last week from husqy dealer... I am open to suggestions.... Willing to stroke port up the cubes...... What's possible on that carriage? ... Lower west Michigan here. Thank you and aloha td
T D hi. There are number of videos in the collection with different zipped 395s spanking other saws. Get it worked on would be my suggestion. Putting a different crank in a 395 "wood" cost a guy a pretty penny.…. a lot of things are possible in the 395 platform. Thanks for watching.
You are Awesome! thank You! @@hotsaws101
food for thought - @@hotsaws101 that scoring on the Intake side comes from snow, water and humidity infiltration during running- at least that's what the husqy engineers say........... saw is from Alaska so that very well may be the case...................... aloha td
one last thing @@hotsaws101 grinding out enlarging increasing the diameter of the intake port where the rubber connects and creating a venturi effect would you need to put a bigger carburetor on because of added air flow? most of these questions come from my limited engine rebuilding expertise (lack thereof) a few old dodge and ford engines and some small engine repair- IMHO-(internal combustion is just harnessing that explosion and turning it into usable force).......... increase the force without destroying the powerplant that is a fine line that is expressed in Top Fuel Dragsters! however their engines are only designed to run one race and then get rebuilt- we want longevity and ummmpffffffff !!!!!!!!!!!!!!!!!!!!!!!!!! (even though i hear dragsters are a hoot to pilot!) thank you HS
ok
What mix oil do you recommend?
66Cashius hi. Depends on the application and a few factors which, until talking to the guy, I do not know. Not sure if there is "one size fits all" oil out there considering the variance from the old school and current smog saws.
Thanks for watching.
