I like the 288 on 272 Northeast chainsaw did on YT.

Any more 50cc saws with 60+cc cylinders swapped in? How about a bored and stroked 70+cc on a 50cc chassis?

Do you know if the 288 and 272 share the same bolt patterns? I have a 272 tore down on my bench, might look into this upgrade before putting it back together!

No idee…my 288 pieces are not currently in my possession. :-/

Generally any 34mm stroke cylinders on a 32mm stroke frame?
Did I read about Husqvarna 55 with 61 top?

I might have one (288) apart in a couple hours. Looking for cylinder bolt pattern numbers?##

Yes, doing quick eyeball match on pictures of the two on the internet, they look really close, however, I did see a forum post that said they are not a match (or they could be matched with some machine work). Looks like bore size may be different (272 = 52mm w/34 mm stroke, 288 = 54 mm w/38 mm stroke) maybe?.

 

[thedude74]

Yeah, 54mm...my calipers off a hair
