Those sound deadening bungs between the fins ?

What's the group experience on the change in sound if you remove them ?

I'm currently deep cleaning the snotty bits of my engine.
Its nearly a year overdue to be honest, following a couple of trips on very salted roads last february.
Obviously I did wash the bike straight away, but the damn stuff gets deep into all the nooks and crannies where it defies access during routine cleaning.

Anyway, I'm currently scrubbing between the fins of the front cylinder and those bungs are a royal pain.
They're dirt traps as well as barriers to one's spoutbrush.
I don't think they help the cooling either.
I'm almost certainly going to remove them but before I do I thought I'd consult the oracle.
There must be a few who have repainted their engines and decided not to bother replacing them ..?
Did you notice any difference in sound ?

Not that I mind a bit of sound anyway, you understand.
Its a Ducati after all.
We like a bit of mechanical noise.

What sound do we think they deal with ?
"Ringing" from the fins ?
Or that "tinking" that I fondly recall from the 2-stroke days ?

Btw.
I have discovered that an Aldi Dremel clone equipped with one of those black nylon brushes, used on ultra slow speed with copious squirts of GT85 will get right into the pores of the engine paint (that still remains !) and restore amazing freshness to the finish.
I've been using the cup brushes mostly for larger areas but the little pencil ones are also handy in the tight corners or up against casting flashes.
Some areas need a second or third attempt as the more baked on grime softens.
And a spare day or two.
