Those cylinders are like hens teeth. I forget who it was but a few years back someone had nos but they where pricey. I have a very nice 10-10S that has been sitting in a box torn apart for a couple years. I get in a bad mood every time I see it.Just putting this out here.
I'm looking for a 10-10S cylinder.
I had a ring catch the edge of a transfer port and really buggered it up.
I had a hard time trying to figure out why it wouldn't run right.
I tore it down and found it.
Now I know why.
