So ive been working on my 02 cbr 600 f4i this winter.and just the other day i had it started next day i went to work on it and doesnt start. everything thing turns on right except when you turn the kill switch the fuel pump doesnt primeand the head light is not on.Ive been looking on here and seeing it is the Bank angle sensor.i have read how to by pass it.and im just wondering if i do bypass it how long will it last for and what do i do when that doesnt work anymore? PLEASEEEEE HELPPPPP

 

If you bypass it, It will last forever. Not sure why you think it wouldn't.

The bank angle sensor is a safety to shut the fuel off and kill the bike if you lay it over. It is not necessary to have, although I do recommend having it, unless for some reason you have to bypass it.

 

yeah i tried to by pass it same thing happend.no prime when i turn the kill switch over and headlight is not on? any ideas anyone

 

did the headlight become unplugged? that will cause a no start.

 

If you are 100% sure you bypassed it correctly, then listen for the relay to click when you turn the key on ( right side of bike behind drivers seat ). If it clicks then check voltage at fuel pump, if voltage then replace or rebuild your pump.

 

+1 to 74Demon, It's my understanding that without the headlight the bike won't run.
