I've got a Rovan engine that has only the "rovan" marking on it. Nothing about size. The individual that I got it from had no idea. Is there anyway to determine what the engine size is? Your input would be appreciated. Thank you.

Oh, by the way, it is a 4 bolt head, not a 2 bolt, if that helps any.

Got a pic of the cylinder head at all ?

Thanks for your input. It's much appreciated. Do you know the piston sizes as they correlate to cc's?

So from what i'm gathering for engine cc bore and stroke specs :

23cc - 32cc all use the 28mm stroke crank

34cc- 36cc use the 30mm crank

latest 45cc use a 31mm crank.
