I just bought an 04 CBR 600F4i. The bike looks great has never been laid down and is complete from end to end. This bike runs great when started up however when the bike gets up to operating temperature around 127 degrees is begins to idle down and eventually quits. I am somewhat mechanical and it seems to me like it could be an O2 Sensor but i may be wrong. Does anyone have any ideas? Any help is appreciated!
