Does anyone know the problem im having with my 06 gsxr 600. I just got the bike with 350 miles on it and changed all the fluids, changed spark plugs, and air filter and removed the exhaust servo when i put on my slip on m4 pipe. The bike when you first start it runs fine i can rev the bike and it will go to 16000 rpms like it is suppost to, but when im ridin the bike and i go to "hit it" i bog down power at about 12000 rpms the bike will never go over 125 it seems its not gettin gas or something, the bike has 2200 miles on it now and its been doing this problem since i got the bike. I heard it is the exhaust O2 sensor but im not sure and if anyone has any helpful tips i would appreciate it this is driving me nuts. Still since i bought the bike have not been able to see what its full potential is.
