HAVE A 748R RACE/TRACK BIKE AND HAVE NOT USED IT FOR 3 WEEKS...STARTED HER UP AND INSTEAD OF THE USUAL NICE FUEL PUMP SOUND THERE IS A HIGH PITCHED SHRILL WHICH I CAN STILL SLIGHTLY HEAR WHEN RUNNING.
SHE STARTS UP OK AND RUNS FINE.
DO YOU THINK I HAVE A FUEL PUMP PROBLEM?
HELP PLEASE AS IT NEEDS TO BE SORTED FOR THE 10TH TRACK DAY AT ROCKINGHAM!
It's never done it before and the fuel pump usually makes a sound as you turn the ignition, then stops...this continues to make a high electrical squeak that does'nt go away. strange
I know it might sound a daft question but is there plenty of fuel in it and its just not running dry? I have a 749 fuel pump if you are stuck but dont know if they are the same or not.
Funny that - I could hear a high pitched whining noise which started as soon as I started the bike & got louder each time I nailed the throttle. Got a single seat unit now, which cured the problem.
