You will need to change the jetting whenever you add a headpipe/silencer.
Go up a few on the main jet and go a little richer on the needle (move the clip down, which raises the needle).

I would start with a 140-145 main and do a plug check to see where you are at. I am running a 165 with minor mods. Check the plug, see if it pops on decellaration. If plug is white/silver it is lean. If it black it is rich. Paper sack brown is right.
I have been going through the same stuff.
Good luck.
