    I know there are plenty of chain saw pros on the forum:)
    I would like to have a second bar for my Stihl ms250
    What would be the largest bar I could safely use on the saw.
    I presently use an 18, sometimes I'd like to use something larger.
    Any help would be greatly appreciated . Thanks,

    Want a bigger bar you need a bigger saw ,

    There is no replacement for displacement

    Yeah, your gonna be pushing that saw to the brink with anything bigger than an 18" bar. You MAY be able to torture it with a 20", but it'll frustrate you.....
    Time to lay out the jingle for a 60-70cc class saw........you'll fall in love with it too! For most cutting I do, I use a 28" bar nowadays unless I'm up in the tree limbing........

    Why do You want a bigger bar in the first place ? You can cut some fairly large wood with an 18" bar ,provide the saw is up to it . One thing to bear in mind is that even though a saw may tolerate a larger bar as far as power goes ,its clutch might not . That can get expensive . This is just My opinion ,so take it for what it costs ...... If You are going to run a 20,or larger Bar, look for a 60-70 cc saw .

    Thanks all. Thats what I expected, I love the saw and the size bar.
    Sometimes I pass up some big stuff because of the bar size. Maybe
    next year I'll get the big brother. Thanks again.

    Gotta ask what You are leaving ! with an 18 inch bar , 33-34"logs are possible with a bit of planning . At any rate, forgo any birthday ,and anniversery ( SP) and Christmas presents ,and ask for an MS461 .If You get the stink Eye ... go with the Ms 441. If things are, still in doubt Go with the MS362 . It won't hurt to take Your loved one cutting ,and while doing so ,just run the 250 at part throttle and really lean on it to make it sound bad . Then look all hang dog and exclaim how You are worried about heating the abode with a saw that is dying !:)
    Disclaimer : I've never tried it . YMMV

    You can go 20" on the MS250, but it's not "official". Probably going to involve converting your clutch drive to 3/8 Picco as well. (Which I would do anyways if you really wanted to go that long.)

    IMO it's no worse than the 20" 46cc Poulans that are populating the box stores.

    I would not go larger then a 18" on a 250 unless I was certain it was only on a pine or cedar or other green soft wood. No oak or ash or anything aged/dry. Also don't dog in too much. Please keep that chain VERY sharp. Tooth/raker condition ultimately matter more then 2" of extra guide /chain length.
