Id put a .020 shim under the needle, 20 pilot jet, and 2 sizes up on main if you have a 380 main go to a 400 and adjust from there

Alright thanks, I already have the pilot jets at .20, even with boyesen reeds and uni airfilters go to 400?

Forsure if you are running Uni filters.CS love timing to.

just go up 2 sizes from whatever is in it now, Im not sure with the uni flows , might go up 3 sizes to be safe,also you might have adjustable needle ,so check that before you by the shims

I have already checked my needles and they are NOT adjustable. So if I went up 2 sizes on my main jet would I add 2 shims to each needle?
