If you do put a 20 inch chain on a 50cc saw, make sure you keep the chain sharp and don't force the saw to cut, as this will stress and overheat the saw.

 

Personally for occasional use, Id rather cut from both sides and get more power and cutting time from each sharpening. A 15 inch bar gives about 13 inches of usable bar, which will block up a 2 ft log from both sides.

Yes and on my 346 the balance is just right with a 15" bar, a longer bar for things like snedding would ruin the feel. Also while I agree a modern 50cc saw is fine for most jobs logging stuff over 12" deserves a 60cc saw, for which I mount an 18" bar.

Yup, totally agree, if you have a larger saw, that's the way to go.  For me its a MS 460 with a 20 inch bar  Also less stressing about the two cuts lining up 😉

I have four 550’s running either 13” or 15” bars on narrow kerf, 18” runs fine if sharp, I certainly wouldn’t go any bigger. 
Looking forward to the new fuel injected Husqvarna 564xp which is currently being demoed at the show in Germany, the weight of a 50cc but the power of a 70cc.

I was wondering the other day why nobody has put a 500i injector and ECU onto a different saw yet.

I've now seen enough husky saw launches to not get excited. How many shows did the 540 592 go to before anybody actually got one? Must of about 2 years from the apf with the 540mk 3 rear handle before anybody saw one, in this country at least. I want the 550ixp and the 564 I'm sure it will a while before we can get our hands on one. Lo

Like an MS400 then?

It's an industry rule of thumb that the ideal bar length is roughly one third of the saws cc's

 

So, your 50cc 550 ideal bar length would be (around) 16" certainly no more than 18"

Ha, you could be correct there. I tried to order some 564XP saws and I couldnt! Ill speak to our rep and see if we can get a decent ETA.
