Is it worth it to big bore an MS311?

[BING38RT]

Yes actually I have. I was given an 2019 Stihl MS 311 that had either been straight gassed or not properly maintained.

Anyways I bought a MS 391 Hyway Titanikel Head Kit that came with a pop up piston and Caber rings. Yes it was a couple bucks more expensive but the saw runs beautifully now. Also I had originally decided to plug the decomp valve... Well after doing that the saw had so much compression I thought I was going to break my wrist LOL So I put a new decomp valve in and matched the saw with a Performance Muffler and now she's my favorite firewood cutting saw. I run a 24/25" bar and you can DEFINITELY NOTICE the Gains when your in the cut.

Hope this helps and Good Luck !

Yep, or burying it dawgs deep and putting a hell of a strain on everything under the covers. Each to their own.
Over here we work on the theory a big saw can handle what a small saw does, but a small saw shouldn't be asked to do what a big saw can.

I get a few smaller saws that are fairly crispy that come in- overworked, I agree with you Bob 100%

The recommended bar for a 311, is a 16". It's your saw, and you can put whatever bar on I that you want. But I'd never have a 25" bar on that saw. I also wouldn't spend any money on hopping it up when it's a plastic clamshell cased saw. Just the wrong tool for the job to me.

Seriously why are you on here ? To quote specs ? The recommended tires for your preius are 12 inch, and triple a batteries. But you know what if you want to run double a I hope you can ask some duch on your preius site. Trust and believe a 311 runs a bigger bar and chain easy. And if you know anything obout chain,chain speed ,pitch,rakets,full,skip,etc., then you know you can run whatever the saw will pill after you've made it not recommended. Hobbieist.
