Gentlemen, 6.0 hp on the 461 & 6.5 hp on the 390. Stroke & bore on the 461 is 36 x 52mm for 76.45cc. Bore & stroke on the 390 is 55 x 37mm for 87.9cc. Let us hope to shout that the 390 has a bit more than the 461 since it's up 11.45cc. It's never going to be a real torquer though. The combustion camber is WAY to big in stock form. One reason why the 461 runs pretty close is because it was based on the 460, which was based on the 046 - which came out in the '90s. Epa regs were getting pretty tight in the '00s. That's when the 385 was being prototype tested. Thanks for watching.
Arcadian hi. The stock 390 got whooped up by a modded 70.7cc saw from what I could tell by the feel during the sawyering and scrutinizing the times runs. There are quite a few videos early on in this channel's collection featuring the 390 platform also. I tested one of the prototype ??? - an unknown 385 in the early '00s. You get a book to track the fuel, weather, elevation, observations, etc., etc. It was, just like the retail versions, fitted with 372 dawgs when picked up at the shop. That was a miscue. It was addressed and ignored. The pistol grip is perfect - if you are Sasquatch. I was never impressed with the width of the machine either. It replaced the 181, 281, 288 platform that was just about bullet proof and noticeably more narrow. All that being said, I cut millions of board feet with the 385 and 390 versions. Somewhere around '06 I had a really early version Psy-Ko 385xp sporting a 54" bar with .404 chain gnawing on a 12' red. Modded combustion chamber & etc. I thought it pulled that length of bar quite nicely for a ~ 85cc saw. I like many/most things about all saws. I also wished there were a few things different in the design of all saws. The 181s were a bit of a departure from the current norm at the time of their introduction. They suited ease of mobility (flickability if you will) and power output far better than pretty much everything else in the early 80s. My point here is, the Husky factory boys took a lot of pointers in the early stages of development on the 181 from Ace Morgan. He owned Ace's Saw Shop. But, more importantly, Ace was a superb timberfaller and knew what worked in the woods from a production stand point. I'm unclear on what happened to that mind set. Seems like now it's just cad a new platform and put it on the market. But maybe I'm way off base in my thinking here. Husky seems to be a little more prone to that philosophy than Stihl from what I can tell at any rate. Thanks for watching.
Skwirl - pretty ingenious user name. Yes, 100:1. I think in part. Some of it is the chemical composition of the oil. I tried it once, and only once, at 50:1 and was not impressed. The piston in this saw was really carboned up for the low hours ~ 20 somewhere also. I saved the piston so at some point we will get a look at it. Thanks for watching.
@@hotsaws101 Cool, thanks for answering! I'm in Australia, had to google "Opti" to find out what it was to start with, apparently we have it here but I've never seen it. I was going to switch to Motul off-road like you said but I can only get it in 4 litre container and I don't use that much so i went for Maxima K2 instead, which was surprisingly easy to find. Skwirl, haha
@@CSkwirl - the K2 is great for a watercooled machine. It might be my first choice in a race bike application. It's not super dense though. The H1-R from Bel-Ray might be a better choice depending on the state of tune of your saw and operating conditions.
Josh hi. Yah, I think the base stock is poplar. I'm just not sure what the hybrid-i-zation component is. It's a wood pulling concern, whatever the blend. The Ulticor went from sad to bad (as in José) for sure. All I can do is hope and pray that the owner will be well pleased too. Thanks for watching.
That johnsered is bad ass ! Happy 4th Jack !
Happy 4th to you and yours Jack . And thank you for all of the videos you share with us God bless havs a awesome day !!?
Kudos to the lovely bride for the assistance in the holiday saw work! The J-red seems like it wants to get out and run way up in the rpm range
Looked like that 390 was a torque monster.
Agreed. Notice how the 390 struggled less on the upcuts than the 461? Torque.

390 the boss.
What is it that you don't particularly like about the 390xp Jack? Besides a bit of width.
Love your work mate

What size bar is that?
A H hi. Noted verbally @ 1:10 in the beginning dialogue. It is 30".
Thanks for watching.
@@hotsaws101 .30 inch. I have a 24 on my 390 xp.
When you said that saw was run on Opti (well i think that's what you said), you mean it was run at 100:1 and that killed it?

Thanks again.
the 390 ran as i expected it would..the Jons. ran alot better than i'd a guessed it would , lol
Hybrid poplar looks like. The j red runs pretty good
