Don´t know if you really ment Jan, or was calling out to Ben, who is the author here?
Anyway, yes you are correctly informed Tommy. The D16 is the smallest engine with the big bore cylinder.
("Big Bore" has 13mm bore & 16mm stroke, and "Small Bore" has 9mm bore & 16mm stroke).
Yes Jan, I know it was Ben's post but I was asking for you to chime in again to see if I was right or not.
Sorry Ben.
