I have bought two OS-30's now and am installing them on my twinstar. I have not run them yet since it is frikin' cold here. As soon as I do run them I will post numbers for both engines to this thread and probably start a new one.

I am still second guessing myself on the saito vs. OS. I will try and get one of these engines on a postal scale before mounting them up.

They are nice looking engines! I wish the valve cover was a bit better for finish, like the HP gold cup engines or the black-crinkle paint on my Chevy V-8's valve covers, but oh well.
