Dave, thanks for answering my first question.
I have another, the new sport version of the Y.S.140! how will this differ from the DZ version. I am looking for the 140 with the most power for some of my larger models.

I have been told the Y.S.140 also develops more H/P than the Saito 180
is this true?

Also do you know if Y.S. has any future plans for a twin!!!
I was looking at the new Saito 200 V-Twin, and the thought occured to me! If Y.S. had a 280 2x140's Now that would be an awesome engine... : )

Cheers-
