Not noisy yet but I tore it down because I had purchased it recently. I use bore gauges and a micrometer to measure so I sure hope I was relatively accurate!
20 thou on diameter... so I will change it before I run it again.

Well the saga continues with this saw. I recognize that OEM pistons are hard to find even used so I took a bet on an AM piston. Only ones available were the LRB and Proline piston and I decided to go with the Proline. Seems like the QC is just bad everywhere because this is what one side of the wristpin support looked like, seems like the casting die was a bit too cold and the material never welded here. There were some other small occlusions/witness marks on various places on the piston but this is not superficial. This is just junk right?
Wow, that's frightening.
Send it back.
Send it back.
Check SawSalvage to see if back in stock. He has some good afm pistons. Chris is the owner.
I use a ton of his pistons to date.

Thank you! I am sending the other one back because that inclusion is just ridiculous. Its hard finding parts at all these days for this saw. I think once its done and good I will sell it and get a 395. PO said this saw was 100% and it had good compression but I guess I should have been more careful.

Just ordered the piston and another set of Caber rings... hopefully its decent
So they have them in stock again? They ran out when I did like 5 of them one year for a guy.
Local drops them off in parts in a box and I put them together for him.

They didn't have the one you previously purchased so I'll take a bet on the other one. What do I have to lose, if its not good I'll just put this saw into a box and wait till something quality comes around

Well, the folks at Sawzilla pulled through and sent me a new piston and it looks really nice! So now I'll have two to choose from (still waiting on the one from Northwood saw). Can't be happier with how the folks at Sawzilla handled it and I definitely would keep using them. Ill update this thread as I get the saw back together.

Finally got around to trying out the pistons in the saw. First off, the VEC was not very good quality and I could not get my hands on an Episan piston which is unfortunate. The weights of the three pistons are:
OEM - 100g (126 w/ wristpin)
Proline - 111g (131 w/ wristpin)
VEC - 120g (141 w/ wristpin)
The VEC showed a lot of flash and was just kind of unfinished as the wristpin would barely go into the piston and the piston was so rough that it would not even physically fit onto the rod.
The Proline was very nice, could have used some softer edges but I cleaned them up with some 320grit sandpaper. The wristpin was almost identical to OEM but a bit thinner. The proline also came with OEM style circlips (one tail instead of two).
Squish:
OEM - 0.055"
Proline - 0.051"
VEC - n/a couldnt get the piston onto the rod
Caber rings fit as they should and dry compression was 130psi, wet was 150psi.
Ring locate pins were in the same place as the old skirtless piston (OEM) on the proline piston but the VEC locate pins were between the intake and transfers.
