Need f4i Help, Running Problems, please help me out!
 

Ok heres the deal, laurens 03 f4i ain't runnin right. at the bottom of first gear it totally falls on its face. I can twist the throttlewide open and nothin, just bogs. then once it hits round 2500 it picks up and runs normal. Not as horrible if shees riding by herself, but once we r both on there its just horrible, this thing can't get outta its own way pullin out from an intersection n ****.

Now heres the thing we tried already, New plugs, fuel tank flushed and clean'd n ****, fuel pump checked, and computer swapped.

Now i'm in a pretty good situation, cuz i have my f4i stunt bike that runs perfect, so i have a perfectly runnin bike to swap parts for troubleshooting purposes.So if u have any ideas AT ALL please let me know what you are thinking, any help would be greatly appreciated!


Thank you very much!!!
