hi, i friends cbr 600 is having a weird problem with the gas level lights, it begginns by lighting the center one and continues lighthing the rest lights both up an down continiusly, can any one help us to fix this??? thanks

 

I'm not too clear on your problem, but when I am running out of fuel the warning bars (thick black bands) flash up and down once the fuel starts to get low. The number of bars decrease as more fuel is used indicating a need to top up. I don't find them very accurate to be honest and there is alway plenty of fuel in the tank when I go to top up, but I suppose it is better than running out of fuel eh? LOL! I hope I am understanding your problem and this helps?

 

that´s a video of the problem, i found that it can be either a problem in the harness from level sender unit, or the level sender it self, my friend is checking that

 

problem solved!, it was aloose wire at the fuel level sender unit
