Anybody with one of these hear two different sounds from engine when riding?

I know these sound like industrial sewing machines but around 2400 - 2500 rpm there is a louder ticking that almost sounds like a knocking.

Never had a faring so it just might be I never heard it before, can I save a trip or should I run out to the dealer and let them tell me "its normal".

The reason I ask is I want to do a stage 1 on it but if I do it first then go up there I don't want them to try to blame the upgrades it there is a problem.

 

Mine makes a similar noise, it's normal.

 

Good enough for me, thanks.
