Piaggio Zip Cat 2005 - stock carb type and main jet type?

[bendover]

I am getting some jets for tuning, but can't find out what carb it is stock. If it is some weird one I will get another one.

This seem to be the one,

But can't tell what type. Dellorto type? Jet 5mm or 6mm?

Due to no one knowing, I took out the tools and took a look:

17.5mm dellorto (confirmed)
6mm main jet (unconfirmed)

I have few Dellorto carbs around and they all are 6mm main jets,I,d just buy 1 may be a 68x6mm which is 1 size up from standard(I think)then get a kit to suit.
