first i would get a new pipe cobra's dont make that much power an make alot of unnecisary noise.i would stick with the stock carb if u dont want to spend alot of money an put a 128 main jet in it.

Depends on how many disks you're running on your Cobra. 130 w/ needle raised 1 position (clip down) and fuel screw out 2-3/4 turns would be my starting point.

woould I just be better off with stock pipe and k&n and lid...would it still need jetted?

i would do that if u dont want to spend much money becuz u wont gain much power from that exaust..if u left the lid on even with the k&n it wont need jetted..but if u remove the airbox lid i would jet it
