RE: New OS FSa-56 4 stroke
I hope the *new* OS 4-strokes are as light as the Saitos and more competitively priced.
I *love* my Saitos and they run *soooo* sweetly (but powerfully) -- it's just that they're so damned expensive!
Mind you, spair parts for Saito are surprisingly cheap when compared to OS (don't ask how I know, it's all to do with unexpected encounters with terra-firma :-)
