HELP: Buzzing sound blow fuel tank when ignition is on! Could it be the FPR?
I've just come back to my 929 after a 2 week holiday, charged up the battery with my usual battery charger but found something a bit odd...
When I switch the ignition on (via the kill switch) and the injection has primed up, I can hear a sort of loud buzzing noise beneath the fuel tank...kind of like the sound an electrical transformer makes.
The bike starts up and seems to run fine but if I repeat the process again, the buzzing sound is still there. I haven't dared go out on a ride yet because I'm kind of afraid it will die half way back home!
Could it be the fuel pressure regulator or the fuel pump dying on me?
