The lower 2 sets of rings comprising of 3 rings each lead me to think that they are original size and not rebored.
I think most after market are just a single ring?.
Im only doing this as it static seized due to water on the pistons from the air intake, god knows how and she wouldnt turn and just this one came out with the head, the others came freely.
It was easy to remove though, very little force was applied just a medium tap with nothing more than my palm on the big end.
So assuming i cant source a std set i just file .0010 until it displays the same gap compressed as the other rings, but it must be from both ends, and im assuming with a standard metal file as im told these rings are harder than the pistons?, thanks for the imput.
