288 and 385 are both 54mm. The 056 also has a 54mm piston.http://northwoodsaw.com/store/index.php?l=product_detail&p=89

 The jonsered 930 is also 54 mm if I remember right. http://northwoodsaw.com/store/index.php?l=product_detail&p=58

Part number 503723502 54mm? http://www.baileysonline.com/itemdetail.asp?item=EHP+503723502

Another parts site says it is. Husqvarna 503723502 PISTON CPL 54mm

Like I said I would have tried the 066 way before the bb046 just by looking at paper measurements above.
I wonder about the skirt on the 066 though too. I can deal with the squish, but that skirt will change the intake timing.

.10 right  about the same as the bb372 in the the 475. The  intake sure seems to make the 475 run. Who knows till we try it.

So what are you saying Kevin? You think i should buy the 066 piston??
288 and 385 are both 54mm. The 056 also has a 54mm piston.http://northwoodsaw.com/store/index.php?l=product_detail&p=89

 The jonsered 930 is also 54 mm if I remember right. http://northwoodsaw.com/store/index.php?l=product_detail&p=58
I know the 385 is out. I need a windowed piston.

If you can get a 505 piston I would get that.

I was going to try a 066 in the 1st 505 I got. The skirts are loose on that one.  I have 2 505 and 1 good piston.   :(

If I am thinking right. I am thinking only .075 on the intake side.

Stihl 066, MS 660
Replaces Part Number 1122 030 2005
Bore 54mm
Rings 54mm x 1.0mm
Height 42.75mm
Head Type Flat
Piston Pin 12mm x 36mm x 7.75mm
Compression/Pin to top of Piston 17.0mm

I think this was the oem 505
top of pin hole to crown 16.75mm
height 42.65mm
pin 12mm

1/4 mm is only .010"

.1 mm =  .004"

385 piston is real tall also. You could add your own windows if needed. The 288 piston is shorter but wider skirts than a 066. I do remember that from when I was going to swap a piston into a 066.

Isnt the wrist pin a different size on the 385 etc then the 066 and 505?
