Hi, i have a 2003 gsxr 1000 and it's bogging after 6k or so rpm. it will like barely rev to redline, and has like half the power it should have. it's intermittent, will usually ride fine for 15 minutes or so, then the bogging happens and the fi light comes on. i got 2 different codes from it, 1 was for the ignition, i took it apart and cleaned it and it hasn't done it since, and the other was for the exhaust servo but that seems to work fine. it always starts fine and revs normally when not in gear, and is fine otherwise. the fuel pump does usually prime twice though, and sometimes primes only once but for too long. i just put a new fuel pump in at the advice of the mechanic i usually go to but he can't look at it for at least another 2 weeks. when i did that it ran perfect for a 20 minute ride then the problem came back. i just ordered a new fuel pressure regulator, hope that's it. sorry for the long read. thanks for the help.
