Whirring or buzzing sound

[Scugog58]

I'm sure this has been addressed before, my 2014 rt with 300 Kms on it has made this whirring or buzzing sound, that's the best I can describe it while idling and have noticed while riding, but not all the time, once or twice after a run and turning the key for start up later on.
Just wondering if I'm hearing things that are normal or should i run it up to the dealer. I have read somthings about fuel pumps, but not sure if that's what I'm hearing.
I just picked up the machine Saturday and I hope this is not the start of somthing.

Could be the fuel pump.
It seems there was a run of bad pumps that make lots of noise.
I've noticed the same with mine. I've owed it for about 5 weeks so far.
I have 2K on it now.
It will be replaced at the 3K checkup.
