Not sure how this applies. I was primarily interested in your experiences with saito ring wear.

Not always, I've seen rings spin in full size engines and I've seen them stay exactly where I put them when I built the engine. I think it depends on the concentricity of cylinder, piston and rings as well as many other factors including but not limited to harmonic vibes. As I mentioned earlier I have seen them spin and not spin in this saito 82 as well.

As with Gary, I am interested in your experiences with saito ring wear Dave.

Yes Pete, it takes a lot of pulling with the valves closed, even more now that the valves aren't leaking.
