Thanks, it's refreshing to see someone that actually have some real experience with it. It seems most people just "know" because they are a purist or a nationalist, or simply because all their friends are..
I have been thinkering about if I should invest in a Hyway big bore kit to my 365/372 kit project, but I already have a Farmertec BB cylinder and it would raize the total cost considerably. I guess the FT cylinder will work fine for me, but of course the devil in the back of my mind keeps telling me the Nikasil one is better.

Thanks, I will stay with the Farmertec cylinder. I got a pop-up piston from Hyway.
I think the best advice is to port map the oem cylinder and the aftermarket timing numbers and measure squish. Then try to adjust the numbers on the aftermarket to better match the oem if possible and clean up the casting flaws. Do not skimp on the rings, bearings or rubber pieces.

Agreed.
Most/almost all of my Stihls were made in Germany and have carbs without limters and choked up mufflers. No Chi-Com parts at all unless I can't find another source of spark plugs.

Easy for you to say that have 12,7 038's that was handed over to yah free to take parts from.

Stumbled upon this thread. As usual, very useful info, thx @huskihl ! I had no idea. Was trying to decide whether to buy a Meteor or a Hyway for my 044; I read that the Meteor is heavier and makes less compression than OEM, I guess it's exaclty the same for the Hyway, then? Also, the Meteor is actually a piston for the 044 with the 12mm wrist pin, with a 10mm wrist pin hole; the model with a 10mm wrist pin (which I have) has a narrower con rod, so there's room on both sides when a Meteor piston in installed. So, I guess this is also the case for the Hyway 10mm 044 piston? Does anyone know?
That info is possibly a bit dated. Don’t know if the where’s and how’s with meteor and Hiway cylinders is still current.
Both manufacturers pistons are cut wider for the 12mm rod. But I have a few 10mm ported 044’s out there still running on Meteor pistons. I’ve heard of and seen the potential problems, but there don’t appear to be any real world issues

Good to know!
I saw a video, think it was by Tinman, where it was said that the stock timing numbers on a 044 are already pretty good. Porting is out of my league and I'm probably gonna be happy with the saw as it is, once/if I get it running properly. So I'm only asking out of curiosity, but do you think it 'needs' to be ported/there's significant gains to be made?
I was thinking about maybe modding the muffler but I'm quite sure it will already satisfy me stock...

Just a note, I’m not a purist type at all. If something works better, I’m all for it. Not a brand snob either. They all have their gems and they all have their turds.
You may be happy with it. No one else’s opinion matters, so there’s that.
They gain from porting like any other saw. 25-40% depending on where you want the power sprinkled about
I used a meteor piston in my 10mm 044 and ended up with .0175 squish with the BGD. It pulls a 28" with out hesitation but I like the es-lite bar in 25" for it which makes a very light saw.

I have an old Husky 350 EPA 2005 saw I just a put a flat top hyway piston in it. The OEM piston on my saw the top was dished. I can already tell just by just feel that there’s way more compression. Gonna fire it up tomorrow, got to late and no muffler yet. got the muffle and bolts, that’s the easy part. Plus I pulled the limiters off the carb. That saw is like an old friend. Never did this before, wish I would of. Had sand the cylinder because it got hot and had aluminum transfer from the old Piston. Looks
real good.
real good.
Cześć. i jak to działa??

I was having my guy rebuild my ms261. I gave him a meteor top end kit. The holes did not match up on the manifold. I returned it and got a hyway which matched up and good to go.
There are different eras of a 261. You likely just gave him the incorrect meteor cylinder the correct Hyway cylinder. The main issue with them is the flaking plating. Hopefully yours is trouble free

The
I do a fair amount of these top ends and porting as well depending on customer needs or wants. The Meteor cylinders port timing numbers are all over the place from one to the next and the ports almost always need a good cleaning up and blending sharp edges dressed up no huge deal if you're porting it anyway but not a good drop on and run. Now I have been told they are made in the same casting plant as hyway but they give more love to the hyway cylinders in the plant maybe that is true I can't say for sure. But if looking for a drop on and run cylinder hyway Titanickle is definitely my choice they are clean ports are shaped as good often better than OEM and the port timing numbers and squish for Husqvarna's are right there with OEM numbers maybe a degree or 2 in favor of better numbers but not seen one even as much as 3 deg off. Now Stihl cylinders are a bit different some of them very but there oems also don't repeat from one saw to the next run. I mean the Stihl oems are not crazy off from run to run but would be hard for a after market cylinder company to match moving numbers. Now note Stihl OEM port timing numbers are fairly good out of the box just need help cleaning them up and improving flow. I'm not as happy with Meteor as I once was somewhere something went wrong and maybe hyway will do the same but for. Now the HywayTitanickle have been coming to me looking sweet even better looking than husqvarna's OEM and pistons slide nice on that plating,yes you can chip them easy if you get in a hurry porting but that's kinda with any plating just a bit more so with the Titanickle but not a deal breaker porting has its risks we take every time. I will keep using them until they go to hell like all the other aftermarket cylinders have.
