Wait. Do ducks have nuts?

The way I see it, 462 replaced 441 and 500i replaced 461. With that in mind I would agree that Stihl has improved their saws almost every time a new one come out.

Re-vamping the 400 at this stage means V1 is a short-run model. How does that affect parts availability and value? The early 550 and 562 aren’t worth much these days. Neither are those early 201t’s. Slight aside, but the battery saws are killing all the 35cc top handle’s value.

It’s interesting Stihl is claiming more torque with smaller displacement. We’ll see, but that sounds like they engineered in some design changes from the porting world. Will that mean there’s less room for improvement?

My main concern is the 362 is a disappointing saw. Why go back in that direction? I feel like Stihl is more worried about the new version of the 562 than they should be. V1 400 is a banger.

But I’m totally biased. Most displacement at the lightest weight is always what I want.

I actually don't mind 441s all that much, in ported trim they'll wax a 440 all things being equal..I know...they're a *b-word to work on.
I had one for a moment, it sounded really strong stock. I looked at how it was put together and i was like nope.

I'm married I have enough headaches

This is an interesting thread,,, as there are a few different comparisons of older and newer saws .

I'll keep on the side lines taking notes’un’stuffs 😉😘

As you well know, everything is relative.
I don't find the 441all that difficult to work on.

This is slightly over-engineered though..

Ya I know, I use them all extensively.

I bet this new version of the 400 is gonna be the ducks nuts.

I don't watch things about chainsaws so I'm not entirely in the know about all the talk around them. What I do know is there is the same exact trend every single time a new saw model comes out, I try not to laugh because it seems disrespectful..I remember the speculation on the 500 :lol: guys thought it was gonna cost 2500 bucks...I could go on and on..the things people say are hilarious.

I can't name a stihl saw made right now that I'd rather have it's predecessor, and I bet this new 400 won't be much different. It may have a growing pain or 2, but when it's all said and done I have no doubt it'll be a worthy tool, the 562 set the bar high..I like the new filter coming on this new 400 and it's overall style from the few things I'veseen and read, I'll bet it handles good and makes power in all the right places for a guy that kills trees for a living.
I am disappointed you haven't mentioned it, but the real issue is how the new 400 will affect the smell of the exhaust. Saw sniffers want to know; asking for a friend.

So far no one has mentioned the Mg piston on the original MS400. If the MS400.1 reverts to an AL piston which is heavier than Mg, it seems to me that could be a factor in producing more torque. More mass will produce more inertia meaning it would be harder to "slow down" when it meets resistance ergo more torque, no?

The two things I noticed from that video is the stock intake horn looks considerably less restrictive. It also sounds like the 400.1 is running more timing advance. So I would guess that stihl is taking clues from the modification community.

I don't know about the piston. One would assume there is a larger piston made of magnesium and smaller one from aluminum. I would be curious about any weight differences. I'm sure the aluminum one is cheaper to manufacture though and that's probably the reason for it.

Listening to the knuckleheads in that video is like taking chainsaw advice from Bob Villa. In spite of those idiot posers doing their best to make both saws look bad, I think the neo 400 will be a more than adequate replacement of the 362 and probably the current 400 as well.

Rotating assembly weight doesn't affect torque directly but can and does make the engine behave differently.
Lighter rotating assemblies actually increased both HP and Torque.

Actually the lighter piston should increase hp and torque. Remember the piston actually stops and starts again at the bottom and top of each cycle. Now a wheel that just keeps rotating would be a different story.
Looks like the connecting rod has been lightened though. I’d be curious to know the weights in comparison to each 400 model.
