There is some talk that having the rotating assembly dynamically balanced can improve matters. One tuner always said Guzzi failed to take into account the volume of oil in the big end, which threw out the balance. Not sure how much 8cc's of oil will affect smoothness, if true.
The BMW's airheads I have ridden have all been very smooth, maybe that is just in comparison to Guzzi's.
The agricultural vehicle linked to in Bernard's post is a single cylinder, as can be clearly seen in the photo he posted. Called Motocarri Ercole in Italian. Agreed that NVH was probably not a high priority for the design team.
Guzzi also made several other 3 wheelers for commercial purposes, looking very like the Lambo, and still current Piaggio APE.
The engine in the military Mullo Mechanico, according to the display in Guzzis own museum, is not an ancestor of the 700cc V twin used in the bikes. In the only poor quality pictures I could find, the crank case is totally different, as are the rocker covers - the rest is hidden under ducting or the picture is too blurred.
I never got to ride a Vincent, although I was offered a running twin for £90 back in the mid 60's.

If you open up the throttles and the engine is at 2500 RPM it doesn't do much. It shakes and feels like you are hurting the engine. Once you have 3000 then it is ready to go though, this is what passes for low end power today.
