Thats a easy fix.  I have many oem ones left over. If they fit.
 But I have sold out of all the 500 5000 490 stuff already anyways.  Still cool to see a aftermarket piston though.

NOS OEM kits was bringing 100-130.  I sold them for what I had in them to friends when I got out of the series.

Did husky use the closed port 44mm   jug on any saws? Have a couple clean 5000s with badly scored jugs I'd like to restore

Only one I know of that fits in 44mm was the open port 50 in husky.  No closed port in 44mm I can think of, maybe I am forgetting one?

There's been mention of the closed port 44mm on other husky motors but I've never heard any definitive responses to that.

I am not sure if the early 44mm 51 EPA saws used an open or a closed port one? It hardly is availiable anyway though, if it was a "special" for that version, as the concept of smaller bore EPA versions was short lived....

Ordered the meteor piston/cylinder kit for the  partner,  I'll post a few pics when it arrives.  Just picked up a clean 51 with 45mm open port cyl.  Piston us lightly scored on exhaust side, cleaned up the cylinder and checked seals, all good.   Maybe overheated with dull chain?   Intake side was perfect, scored width of exhaust but ring wasn't stuck.  Kinda odd.

Found some "slab side" 45mm oem pistons that might work well with the open transfers. Anyone know the original application for p/n 502 128 002 was?

Coming back to  Jonsered RS52  RS51 502128002 PISTON CPL 45 MM  oem $87  ( I havent a clue on what saw that is). I see that part number for husky too, but cant figure out in which saw.

Jred looks like a clearing saw?  http://www.jonsered.com/ddoc/JONI/JONI2002_AAaa/JONI2002_AAaa_106274262.pdf
