Ok, I am in the middle of rollering my GRiSO, right is done without issues. So I am closing up the right and realize that there is a clean spot I cannot account for; as in "am I missing a bit?".
I know it is a picture of the left cylinder but same on the right. Question is, what goes in the left threaded hole? To the right of it is the oil line attachment point but what is the left one for.
OK, age is kicking in but I cannot account for a part that goes there?
