Thanks for the information. Any little bit is nice. But I was also thinking along the lines (Sorry I didn't mention it) about the overall dimensions of either the YS-63 or the YS-53 (if they are different) Like I mentioned above I am planning on getting these for a project and am curious about the room I'll have to work with. Overall height, width, length, possibly center of crank in comparison to bottom of crank case etc.

Edit: I know some of these dimensions are on the above post. But a main measurement I need is the center of crank to bottom of case.....and also wondering if in fact the 53's are the same measurements all around?

Thanks again
