What have been people's experiences with installing newer engines into their Paso 750?

The reason that I ask is that I recently picked up a 916 engine from an ST4 that came with the throttlebodies, wiring harness, computer, and airbox with K&N filter......



I bought this at a reasonable price with the idea that I could install it in my 748, ST2, or the spare Paso 750 frame that I have for a future project. I went to install it into my Paso rolling chassis...



...to limit the amount of space that the engine would take up, and I noticed a few things......


1) The mounting points on the engine between the cylinders and at the top of the rear of the cases were 1-3mm too wide on either side.

2) The mounting points on the engine at the bottom rear of the engine cases are too wide by close to 3-7mm on each side.

3) The mounting points for the swingarm on the engine cases are considerably wider on the ST4 engine. Probably 15-25mm on each side.

4) Looking at the engine on my 748, it looks like the swingarm mounting section of the 748 and Paso engines are of similar widths.


Anyway, I was just curious as to any issues that others have had in installing a newer Ducati engine into a Paso 750 and what you ended up modifying.
