^^^^^^^^^^maybe...maybe not. But trying what dmfdmf says is not a bad idea.
The sock on mine was cleaned first. Whined still.
Then I back flushed the HP filter. Fixed for a few thousand miles. Whined again.
Replaced the HP filter. Fixed.
I buy top tier gas all the time, premium usually.
I should add though, as well as whining, the bike would get where it would not run above 7,500 rpm or so, like it had a fuel cut off. Even with a clean filter system, the fuel pump was a little noisy, but I have great hearing.
