I've run a MS390 (stock) with Stihl Full Chisel (33RSC72) on a 20" bar. It pulls that with authority. If you wanted to go 24".... I doubt it would have trouble with that and if going full-skip seems too extreme there's always Stihl's half-skip full chisel....
I'm not a fan of big bars and don't use them but this is extremely good advice if using a bigger bar than what is recomended by manufacturer.

Stihl recommends 16"-25" bar on a 390.

Just sayin'

I think we already take those reccomendations with a grain of salt. Right Jay? ;-)

Oh man! They updated the bar reccomendations for the MS880. Used to be a 21" bar, lmao! :lol: Now it's 16-59".
 
That would be an awesome saw! MS 880 with a 16" bar & 3/8 picco chain. LMAO

Are we talking about the 390 or 391? They are different saws, and the 390 will run up to a 25" bar per Stihl.

EDIT - It's interesting that the 391 has 14% more displacement that the 291 yet Stihl recommends the same bars.

they need an astrik in there for a 391 w/MM...JMO

*This saw would have to be the poster child for opening up the Muffler.


get a 20 in bar too is my suggestion.

jay mentioned something earlier about the weight being a benefit on this model for running a larger bar.
I never thought about it that way... I always took weight as being a bad thing
