Ok right now I've got a FMF Ti-4 slip on and a K&N with no lid and Im running 40 pilot and 155main. Im now adding an 11:1 wiseco, Hotcam stage 1, grinding the welds on the stock header, and I switched the K&N for a UNI, but still open lid. I planned on switching to a 42 pilot anyways to help with the cold starts. What should I start with for a main. I was thinking like 160 for main. What do you guys think? I just need a ballpark for now and then I can do my own testing. Thanks
(I would prefer you have the same mods or at least no someone with same mods rather than guessing)

Thanks guys

42 or 45 should be fine, you will just have to fine tune the bike in using the fuel screw either way.

a 160 should be a good starting point.
