Re: Fuel pump noise?
Had a 60 mile commute with no noise. Next day, noise came back on the afternoon ride home (heavy traffic). Warmer in the after noon too. Pulled into a gas station & after the fill up, the noise was gone.
Friday, the noise came back again just as I was arriving home (quiet on my morning commute). Popped the seat to hear better & the noise didnt seem with certainty to be coming from the ABS area. I was able to put my ear to the tank & it did seem to come from in there. So hard to be definite about anything as when the bike is running, the noise seems to be coming from everywhere & no where...
So one thing seems to be a factor - heat. No noise on my easy & cool commute into work. Chronic noise appears on the warmer & congested commute home.
I have a mechanical stethescope. Next time the noise sounds, I'll try to pinpoint with it. Otherwise, still uncertain whats going on...
