Thank you to Dukedesmo and Luddite for the info. It seems to confirm my hunch that piston rotation is responsible for fluid blacking and that Ducati were there long before me with the pin idea.

It just remains to be proven whether or not the later pinned rod would be a straight swap for my early one. I am assuming that I would need an anti rotation insert (#22) which I am also assuming would fit straight into my Oberon cylinder.

It stands to reason that I would omit the spacer if fitting a later rod.

Interesting stuff... Might be on the blower to Moto Rapido in the morning. Unless someone already knows the relative lengths of the two versions of rod?
