Hi All -

I know Stihl says the MS 271 is capable of handling a 20" bar, but does it lose power going to that length? Does anyone run one with the 20" bar?

Thanks.
 
I'd go 16" but I have larger saws when I come across larger wood. If you are frequently cutting trees that exceed the 16" bar then I'd go 18"
 
The MS271 will turn a 20" easily. As long as you NEVER use it to cut wood, ice etc... I would stick to 16" and maybe an 18" on occasion. Make sure the chain is very sharp and stay away from chain that is too big.
 
They should have no issue swapping to a smaller bar. Burn up the motor? Not exactly, but you could melt the case if the clutch gets too hot. I have seen that in some Stihl non pro models. Also you will fight more cutting wood since the saw does not have the HP to turn that bigger bar.
 
I have the 20" bar and have had no issues with it. Just a weekend firewood saw is what its used for. Will not noodle wood.
 
Thanks. Last question, why would they put a 20" in the specs if it shouldnt be used?

It **can** be run, it just won't make for a very lively cutting experience. Folks like to over-bar their saws in the US, so much so that saws are often sold by bar length rather than engine displacement or power output, both of which are more useful measures in most instances.

Look at it this way: you can pull a big camper trailer with an f150 and be within spec, but we all know it will pull better behind a 250 or 350.
