Hey guys my 2004 CBR600RR has a problem with the fuel gauge or the fuel system itself, or atleast it thinks so. I just recently replaced the battery and the bike runs fine but the fuel gauge is scrolling up and down, the manual says its when the fuel system has an error the gauge starts to scroll like this, and it says bring it to your nearest dealer. I prefer to do the work myself though but i'd like to know where to start, i'm wondering if its just a plug under the tank that maybe came loose or something? Any suggestions?
