Pay no attention to the twaddling on about RE buying Ducati.
Just look at the pics.

There's some deception going on, rear head shows no evidence of a frame mount on the right side.
Top views show a big mount on the left side.
This pic of the complete bike shows a big honkin' frame spar terminating in that area.

Would one call that a deep sump?

Kind of looks like it's the injectors that moves... or am I missing something?

I think the whole thing slides up and down on those posts about 50-60mm.

Actually maybe more as the stacks look in the middle position. The rail looks fixed and I wonder how much the shower type injectors move. The closer I look the less sure I am. From the other angle it looks like the whole shebang moves on those posts. From the posts and sliders they could also be in the top position and only move as far to meet the lower stack.

Got the Ducati official email. Compression ratio 14:1

Email I got states 2 injectors per cyl. One above and one below the butterfly. The lower one is for low load application and the other is activated when needed.

The upper velocity stacks appear to slide up and down on the silver posts, 2 front, 2 rear.

The upper injectors appear to be held by some missing bits likely attaching to the airbox.

Big loss of torque. I'm wondering how it will sit. I rode a friends inline 4 and it felt like I was sitting on a horse. But I haven't been on a V4 in 20 years and I didn't have the VTwin reference at the time.

I didn't do it.

I doubt a loss of torque... It should sound like nothing else:
