Boy, mine sure didn't with a 25" bar.Mine oils a 25 inch bar just fine, i do have it maxxed out and wouldn't run a longer one. but have done a lot of noodling without it overheating.

I don’t think you’ll be disappointed in making the switch. Consensus from research on here and other places Stihl light bar is a tough one to beat.I just sold a ms391 and going to buy a ms400 with 25” bar. I can upgrade to a light bar at time of purchase for a few bucks more. Is the Stihl bar the one to go with or maybe one of the aftermarket ones if they can. I’m just cutting firewood for myself so not getting a big amount of use. I’m after weight saving the most. The 391 was a tank so hope to be able to have a noticeable difference.
I don't doubt it whatsoever. The 400 sounds like all of the autotune saws I have ran and/or listened to. They are on the edge of lean. Speed at the expense of torque. Great for limbing. Compromised when bucking full bar cuts.I highly doubt he can tune as well as m-tronic or any other electronic fuel management system.
I put three new bars on the scale, all use the same driver link count:I just sold a ms391 and going to buy a ms400 with 25” bar. I can upgrade to a light bar at time of purchase for a few bucks more.

Oiling a 25" bar is not a problem, the MS 400 oils conservatively the way most every new STIHL does, their bars and chains are designed for it. I max out the oiler on large logs but turn the oil setting to minimum for brush cutting otherwise it will over-oil. For sappy stuff you could turn the oiler up and coat the bar with the excess oil so it stays clean.I've read the 400's oiler is pretty well maxed out with a 20". I don't own one, but it sure wouldn't hurt to ask around before spending $$$$$$$$.
This is exactly right.The m-tronic saws are tuned right. They don`t have to be pig rich as most guys like to run their saws. They are slightly on the rich site which is enough.
Bar oil is what lubes the tip regardless if it has a grease hole or not. Any grease you pump in the tip is expelled almost immediately once you start cutting. About the only time I grease bar tips is when I lay them up in storage.I put three new bars on the scale, all use the same driver link count:
STIHL 25" Rollomatic ES (Germany): 60.5 oz = 3.8 lb = 1.7 kg
Sugihara Lightweight 24" (Japan):
46.5 oz = 2.9 lb = 1.3 kg (23% lighter)
STIHL 25" Rollomatic ES Light (Germany):
41.5 oz = 2.6 lb = 1.2 kg (11% lighter yet)
To me the differences in handling are noticeable. If one considered the MS 400C "a bit heavy" with the ES bar it's "pretty darn good" with the ES Light bar.
STIHL currently does not have a grease hole for the nose sprocket and considers them "permanently lubricated." I have to wonder if they designed the bearing system to use STIHL bar oil as it is very tacky and could possibly do the job--"permanently lubricated" seems a bit of a stretch. I run STIHL bar oil on ES bars ("E-Super" bars, not "E" bars which are laminate) and haven't had an issue. (The Sugihara has a grease hole.)

The ES Light is a very good bar. I have one and a cannon light bar in the same length. The cannon is a very nice bar, but is heavier than the Stihl light for certain.I don’t think you’ll be disappointed in making the switch.

Side note. I don't have a 400 piston and package to weight it.
They said the weight was reduced. So, the way I interpreted the weight was compared to the average 50mm piston not made of mag from a strato engine. Could be wrong and it's compared directly to the 362 piston. It should be compared to the 441 piston. I might be getting the weight on that if I decide to tare that down although it doesn't need to be. Porting would definitely help it. Feels all pent up with a long blowdown I'd suspect. Never timed it. Never timed one period. Never did a top end on that or a 400. Likely Kevin has all that stuff written down by now for weights.
Nope, not lean or even in the edge of it. There's a big difference between pig rich and tuned right. You're used to tuned rich. Which isn't wrong, but its sure not right.I don't doubt it whatsoever. The 400 sounds like all of the autotune saws I have ran and/or listened to. They are on the edge of lean. Speed at the expense of torque. Great for limbing. Compromised when bucking full bar cuts.
I guess a lot of that test depends on where the income for the video originates from. 4.4 hp vs 5.4 hp.It's right for full bar bucking, imo. Oh well. I guess my explanation why a 60cc echo runs equal to a 67cc Stihl doesn't cut it with you guys. I was trying to give the Stihl a way out of being owned in a test.
The 400 doesn't look very special in that test. At all.
Pig rich is a stretch for how that echo is tuned. Imo it's perfect. The Stihl is lean in that application. Imo.
I like it when my saw has that perfect little warble in long cuts. On the edge of rich is not pig rich. On the edge of lean is the autotune way, but whatever floats your boats I guess..
I’ve watched other videos from that particular channel and he’s looked for things not to like about the 400 since he got it over two years ago.I guess a lot of that test depends on where the income for the video originates from. 4.4 hp vs 5.4 hp.

The guy was a stihl tech and owns a bunch of stihl's. He was just comparing them.I guess a lot of that test depends on where the income for the video originates from. 4.4 hp vs 5.4 hp.
To do a proper test would require identical wood and an operator very skilled in saw operation. In addition for any sort of valid statistical analysis it would require way more than one cut.The guy was a stihl tech and owns a bunch of stihl's. He was just comparing them.
But I learned alot of folks test different. Like him dawging in isnt the way I would do a speed test for time.
I'd be listening to the r's doing a straight down cut. Not pulling out of the rpm during the speed cut for time.
400 562 tested better here. Couple different ways in cuts.
