[FF1O5]

Is my 165 main too big for the mods in my sig?Im running the air/fuel 3 1/4 turns out with a 42 pilot and i have popping on deceleration.I left the needle in the stock position and it seems to be running good except on deceleration.thanks.

If its popping I believe that usually means its lean, not rich...

i think the 165 sounds close. I would raise the needle. Move the clip down one. Thats what i am at, and i only have a slip on, you have a full pipe. Stock clip seems to lean for your set up.
