Seafoam in a plastic fuel tank?

[Ion66]

I've always used a bit of Seafoam in my vehicles, but I noticed a "No additives" message on my Breva 1200. Since I've not had a bike with a plastic fuel tank, or internal fuel pump before, I thought I'd see if anyone has had any experience with Seafoam and a Guzzi?

I put some in my Stelvio.... sure hope it's OK.

I have used it several times in my Stelvio and so far so good.

if you need it, use it.

run it through on a single ride and no worries.

Hasn't caused any issue in my plastic B1100 tank.

Use it on the dirt bike all the time. Maybe I should run some through the Griso.
