Is not honing done to create a good piston and ring cylinder seal? Quick ring seating and good seal are what I look for.

The top fuel dragster application has no correlation what so ever. Chainsaws have NiSi/chrome lined cylinders.

Cylinder finish and sealing are my only consideration,they are what I've always used,if you like a different type of hone,fine by me. Each to his own...
I didn't state whether you should hone or not...simply that your comparison is of no merit. Completely different materials and application.

I disagree,cylinder sealing and piston ring and cylinder breakin and sealing are related,be it a cast iron bore,nikasil or chrome. Also the crosshatch left retains oil for lubrication in 2-strokes,also I only hone for a few seconds so not to thin the cylinder plating, the old chrome was tough,but nikasil is pretty thin,I hone as little as possible on them. I don't know why the ball hone goes in the garbage can for saws. You surely don't use the ancient 3 stone hone, do You?

Nope!
Nor any other hone either.
There are just better ways.
But to each their own. Your saw do it your way.

I'm OLD, FAT and crippled!
But I keep waking up every morning (or at least some time during the day) so life is good!
Sorry I didn't know about your GTG in time to make plans, I'd love to see a bunch of youall again.
Guess I should get back into the loop a little. Hope everything goes great for your GTG.

No hone at all?!
Yea ok ,do it your way... Well each to his own...no crossshatch for efficient ring sealing or retaining oil...

Gonna do it again next year. First weekend in October again.
It was great having Andre @Andyshine77 there this year.
The original factory crosshatch is already there. You just have to reveal it with a good cleaning.
It takes a lot of pistons and rings to wear out the factory crosshatch in good chrome. Lots.

On normal car engines with cast iron cylinder walls, I thought the reason for honing was to remove the glaze and smooth out where the ring ridge had been, and to get a good crosshatch for ring seating and oil retention.
But on a chrome or nikasil cylinder in a 2-stroke, do you even get a glaze, much less a ring ridge?

i rebuild piston aircraft engines for a living. Steel cylinders get honed and chrome ones do not. We chrome cylinders when necessary to bring them back into spec. which is rarely done anymore.
Do you know how hard Nikasil is? I believe there is a place for honing some cylinders, just not Nikasil plated saw ones. Some of the guys offering advice have rebuilt more than a few.

Are you sure its not a 311Y? Just asking since I have only worked on very few saws.
In this case honing, or sand paper and finger, Muratic Acid, or whatever is to get the aluminum transfer off. The less effect on the plating the better.
If it is a Piltz he could probably use a 60 inch.

Well I will be damned. It must be a special model. It has a 311Y sticker too.
Now.....about that blade.
The guy at the saw shop tried to sell me some sort of chisel chain attachment for it, but I can't find the hammer setting to run that.
I just want a dang regular blade.
