Jack I would like to see a video on how you grind/file your chains. In particular your coast vs inland chains. Close ups would be great too. Thanks, Bill.
Bill hi. I don't think it is so much about the "how" as it is about the set up and/or angles that the teeth end up at. The relational distance of the side plate to the top plate plays a role as well. I've looked. It is hard to tell when I know what I am looking for/at. You get a "feel" for the position while hand filing of where (the angles) your file needs to be in order to achieve this too. It's not a huge difference for the most part either. Thanks for watching.
Watching these are like watching video of old time hot rodders. I find myself really listening to the sound of the engine as it's idling, being revved with no load then under load. The times are of interest but only in a "how fast a quarter mile" way. Thank you Jack and Master Payton.
I would love to see a comparison of this level of zipped 390 against a similarly zipped 395. I believe the engine design is quite different if I recall correctly from one of your bench videos.
Daren hi. It wouldn't be much of a contest. the 395 would annihilate the 390. ruclips.net/video/iufiuhhQlz0/видео.html shows a similar 390 getting bested by the next level down 395. Once the combustion chamber work and flow tricks enter into the equation, it's bye bye smaller saw. They are pretty similar in engine design. Quad loop & 90º alignment of the cylinder to the cases/crank/line of the chain travel. Flow travel is similar coming in and going out of the intake and exhaust. transfers both on the side. Albeit coming in on the side of the 395 cylinder and more from the bottom in the 390. A little more volume capacity in the 390 cases right below the start of the transfers & more of a "motorcycle" style piston. I was thinking that they were pretty close from an overall perspective. Thanks for watching.
Adam hi. The Husky saws are a known quantity to have over achiever oilers. If the fluid cannot get down the bar groove - for whatever reason - then it will be running out where gravity takes it. Thanks for watching.
That chain is hogn the power. Looked like that log was froze quite a bit . Not rock solid frozen . But still alot harder than thawed out. How many tooth sprocket do they have on them ? Half wrap handle bars totally suck on a bushlin saw !! Good job on the hopped up saw that's impressive rpm in the cut with full comp in healthy froze wood !
gumboot65 hi. 7 pin/tooth sprockets. Yes, frozen. I dawged it in there to see how the chain responded. Which we see was plenty aggressive. Thanks for watching.
A H hi. I was discussing that at around 1:40. It's a 110 driver 3/8 length bar. It measures 33" if you use the same method as with a 104/5 3/8 driver bar which is 32". Thanks for watching.
I used a 36" bar on my 390s & one of my 385s and cut in the millions of board feet. It was pretty peppy though. Longest bar it saw was a 54" with .404 chain. Did better than I thought it would. Thanks for watching.
@@hotsaws101.thank you very much for your reply. I have a 390 xp with a 24 inch bar. Great saw. The 2017/2018 models 395 xp are made in sao Carlos BRAZIL

the art of grinding, something that is much more difficult than it looks.. at least in my regard
I had a few of those medium sized dogs off of parts saws mostly older 460s and I took one of those dogs and put it in my ported stihl ms 170
👍👍👍
How do those bars hold up in the field? Are there better light weight bars?
Davis hi. Fine for the finesse type faller. Not so much for the other type of faller. Doesn't really matter now, they are nla.
Thanks for watching.
Does anyone know why my 372xp and 390xp drip bar and chain oil on muffler when I make cuts clutch side up? Thanks

Ok...👍
Dammitt boy how much to Port my 390 xp
Same

Great video on the 390. What size bar are you using?

@@hotsaws101.thank you for your reply. 33 inch bar. Is it not to big for the 390 xp.
