i recently done a engine rebuild mods listed in my Sig and i put a 450r carb on to, it went sweet as but today off idle when its warm when i punch the throttle it hesitates.

my jetting is
180k main
needle in the middle
48 pilot
air/fuel mixture 2 1/2- 2 3/4
changed the plug and it still did it.
it just hesitates when i punch the thortel on idle, its OK when im riding it flys, got any ides guys.
