New Moto Guzzi Door Mats Available Now
It's purpose is to hold the two shafts (assemblies 12 and 13) which the rocker arms are on.
On the 8 valve models they have the same bit. The valve cover is 'floating' in rubber gaskets and grommets. That keeps the valve cover grounded in case there is a spark plug arc to it.
I have a 2019 v7iii and I noticed this part while inspecting valve clearance. My initial thought ( like Wayne) was a ground path for the valve cover. If it is indeed ratling against the cover perhaps you could put a bit more bend in it.
For sure ?
Sorry, I was referring to part 6. I read the diagram wrong.
