748R PROBLEM?
 

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!
:barfy:

Mine does that from new, I think you are just noticing the fuel pump actually working

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.

Had to go check once you said that!
all is fine with fuel....half tank.
maybe it just needs another good hard run to clear/show up any glitches.

mine makes that noise if its runing low.
But does stop if i turn it on and off a few times

cheers matey,
topped up anyway and did as you suggested and stopped!
not used to all this italian finery..used to race jap bikes.

must say though that i'm absolutely loving every minute of it!!:D

glad the problems solved. just shows sometimes the simplest things work. ;)

mark do you want to swap a 996 fuel pump for your 749 one???????

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.:D:D:D

:lol:

I'm gonna have to try that, maybe it will get rid of the annoying kidney pains I seem to get when filtering fast or going 100+ ;)

I knew what was coming but that still made me laugh like a loon! :roll:

nah! sorry nat I do have a 748 and a 749 and kept it just incase one of them decided to give up the ghost. is there any differences? the spare I have is out of a 749s I should check the parts numbers.
