Main jet size for fmf turbine core 2?

It has a 320 main jet in there.

I learned what a main jet is from this site I:I

If your asking what jet size you need, we will need all other mods as well....

Other things are just some rear breaks and bigger tires. I don't think anything else was put in there.

I think he may have been asking what mods to the motor, like pre mix, air box lid, airfilter, they affect jetting.
