Rollers & jet size advice.

Hello,
I’ve recently purchased a Piaggio typhoon 125 2t.
Just wondering what weight rollers I would need if I was to purchase a 172 kit & also what size jets I would need?
The bike already has a dellorto PHBL 25mm carb, but not sure what size jet is in there.

any advice would be great.
Thanks

 

std 12.5g rollers are fine, I'd go 110 on main jet try it then work down if too rich.
