carb jet size?

I have a brand new polini 4.2 carena a/c

I wondered what the main jet size is, so I don't have to take the carb apart to find out.


I think the stock carb is a Dell'Orto 14mm SHA 14-14L (correct me if I'm wrong)

also am I going to need to change the jet with a air filter upgrade?

I'M PRETTY SURE ITS A 68...... IF YOU ADD THE INTAKE YOU RUN A BIGGER MAIN JET ( 72 ) . THIS IS WHAT WAS RECOMMENDED TO ME BY TED@INLINE SPORTS IN SUNNYVALE WHEN I DID THE INTAKE UPGRADE.

yeah I found out its a 68. I bought a 70 size. I've heard that I can go up to 72 no problem, and maybe 74.

I'll start out with 70 and try a 72 if I need it.
