I put the 52mm BB kit on my 365. Can I use a Meteor piston for a 272, or 281 in that saw? I want to have a better piston and ring setup broke in before the GTG without buying an xpg OEM piston kit.

Right, but what I am asking is if the 272 (52mm), or 281 (52mm) piston Baileys sells will work.

I am pretty sure the 281 is out of the picture..it has longer stroke...not sure about the 272. You need to check the stroke....

I belive the Husqvarna BB is 51mm.

Piston length and wrist pin offset are different measurements. It is not a direct replacement, you would need to calculate your timing numbers to determine piston or cylinder height modifications.

Bow, what's your issue with the kit piston?

For one I dont trust the rings. I might find different rings of better quality. If I could put a meteor piston in it with rings, I would. The BB kit is running fine, but I think the rings arent up to snuff.

the aftermarket BB kits are 52mm,,,the Husqvarna XP(R or whatever) is 51mm.

The 371/372XP OEM is 50mm.
The 281 wrist pin is also 13mm...
The 375k/new 372XPW are 51.4mm OEM...

Jason-
Here's what I've done in the past with 365/375 Bailey's big bores:
038 Magnum piston and rings: correct crown height and wrist pin diameter, had to machine out the wrist pin bosses to clear the wider Husky rod by 1.5mm on both sides. Skirt length was slightly shorter than the included Bailey's BB 372 piston.
272 piston and ring: correct wrist pin diameter, slightly taller crown height. I used a 2mm base gasket. Made a good running saw. Skirt length was about the same.
064 piston and rings: correct wrist pin diameter, but crown height quite a bit taller so I turned this one down for a pop-up. Skirt length was slightly longer so I trimmed the skirts, it made a real good running saw.
