I agree Steve.
Plus SawTroll who is very critical about weight should know the chain is lighter too . :D

How much power will it stand before it breaks , I'm running 3/8's on this ported 261 and it cuts just about the same in hardwood as the stock 372's /461's

I've milled a few thousand feet of 2"6" lumber on my Alaskan with this little Picco on my 066 Mag.
Still haven't broke the loop yet.

Just picked up a 261 and the dealer had no idea about running Picco on it. Sounds like I'm gonna have to cross the bridge and try to find a tuning kit in Windsor. Any idea on the model number?

Holmen, what size bar are you picco-milling with? And how long would you go? Wondering if I should make that adjustment too. Thanks,
Adam

aSmith, welcome to FF, I believe these kits are no longer available on that special price (been a few years ago) but the Logosol 16" bar is still in inventory.

I ran the 16" Logosol Stihl sells plus a 7 TPicco spur sprocket drum Stihl also sells for the 066/660.
I was milling cants with to my 090 on a 36" Alaskan.
Then when it was time to mill lumber off the cants I mounted the 066 with 16" Picco bar/chain in the Alaskan mill.
When I had a hired man he would run the 066/16" on a homemade mill set at 1 1/2" while I kept milling cants with the 090. We cut over a thousand bf one day milling 2"6"16' spruce.

I tried the Picco chain on the 36" 090 mill but in time the chain kinked up too bad with all the chain stretching.

The 63PS is indeed great chain however has been NLA at Stihl for at least a couple years. The green tag version is much slower in my experience about on par with N1C Carton and 91 Oregon. Luckily  I have a lifetime supply  of 63PS since I dont use that much of it :)  Baileys does  list it on the web site in both loops and reels.

Stihl 63PS chisel is still available from dealers here in Canada last time I looked.

Been considering to switch over to 3/8 low profile (3/8 picco) on my 261C-M to pair up with my 241C-M which is a fantastic limbing saw. I see this tuning kit (as mentioned by the OP) is for 16 bar and chain. I already am running 16 on my 241 for better reach when limbing. I currently am running 18 .325 on my 261 and would like to keep the length the same. Looking though the bar and chain catalog I found 3/8 picco 18 bar under the model 250, part number 3005 000 4817 

Anyway, can I run this 18 picco bar on my 261 and if so, what is the sprocket part number? And how many links 3/8 picco chains would it need for a proper fit? The catalog says the 16 bar on 261 requires 60 links.

Its not going to fit. That saw takes a 3003 mount. Keep on going. If you wanted Oregon part numbers I could help, but Stihl is more proprietary than I can look up.

Not apples-apples, but I had interest in converting my 026 to using picco chain; ideally with a 20" bar. It looked like it was gonna be more trouble than it was worth to me, using aftermarket parts, and requiring modification.

You should be able to use the newer Stihl 23RSPro chain on your 261 (you need a 0.050 / 325 bar).  I have been using it over a year now on a Husky 346 and it has never run better.  I also use a Stihl 241 that runs 63PS with a 7 tooth rim sprocket.  You could fit your 261 up to run 63PS but I think 23RSPro is a better option.  You can run 7 or 8 tooth rims depending on what you are cutting.
