Modern Vespa

Could anyone tell me what the standard jets are for this carb and motor please. I've done a few searches and reviewed two Spanish manuals that I found online but can't find the jet sizes anywhere.
Mine isn't stock, it's has unknown porting and a sip road 2 exhaust but knowing stock would help get in the ball park.

It currently has
52 pilot
225 atomiser
84 main

I can't ride it yet, need to sort registration first, so this is really just about which jets to start with, tickover is lumpy at 1300rpm and stalls if set lower

Also timing, stock is 27 degrees, I've got it timed to 24 with a sip vape system as I've read a few posts on here that suggested dropping 3 degrees when going points to cdi as the cdis timing curve retards by 3 degrees at tickover.

Edit: multiple typos

I may have that somewhere.... let me look.

Ride it. Don't wait for the reg! take it up and down the street and get a feel for it. It may tell you if the jetting is generally OK.

PS post pics... we don't all read "the articles" ya know.

I get out of the area asap on all my bikes, too many theiving chavs about. I could stick it in the van and find somewhere else to ride it.

GL frame in case your wondering why it doesn't look like a MotoVespa

As far as I know,


50 pilot
255 atomiser
82 main
C-2 needle (to be set in the 3rd slot)
float 7,5 gr.

Hope this helps, nice scooter!

Thank you. Since I'm a couple of sizes up on the pilot and main its probably already a good starting point. Needle is C2v on 3rd slot. I haven't checked the float weight, but I have had to flip it as whoever worked on it last had fitted it upside down.
