My engine has 3 holes on the back. 2 small ones are on the height of the swingarm axle (I wonder if these are original) and there`s a big one on the bottom right.
My friends Cagiva Elefant 900 engine doesn`t have any of these.
I have them on my engine too. I assumed the two at the top were either for non-installed grease fittings or to clamp the swingarm axle for ?? reason. Have no clue on the bottom one.
I'm pretty sure they have hex screws in them. I have a photo of the engine while I had mine apart but the resolution is not good enough to tell for sure.
I happened to look at my spare engine and it appears that there are roll pins in the 2 small holes.... the other large one not sure what it was intended for, maybe an oil line?
