Hey guys i'm new to CBRforum but i've been a member of the biking community for almost a year now. I have a CBR600rr 2004 that's been giving me problems lately...

I've seen many threads with people with similar problems but my bike seems to lag or is weak in 1st gear in low rpms. Once it gets roughly above like 5-6k rpms the power kicks in and the bike shoots forward and runs smoothly just as it normally should. In the low rpms when the power is weak, it is also gives me a much lower growl than what is normal (it almost sounds like a gargle). There is no clanking or any other noises from what i can hear. Is this a fuel injection problem or is my bike just dying... Anyone have any suggestions or tips for me? i know the power that my motorcycle is capable of because this happens like 4/5 times when i start my bike off in a slow roll.

CBR600rr 2004 .... little over 40k miles, help please!
