Light whistling sound at 23-24 MPH
Has anyone experienced riding and while either accelerating to 23-24 MPH or decelerating to the same there is a very light whistling sound coming from the engine? I noticed it once and thought it was the road, but I’ve been trying to access for about 2 weeks now and finally pinpointed when it happens. It’s at those exact speeds. Wanted to ask and I’m thinking about taking it in. It’s still under my CPO warranty. Please share if you’re familiar. Thanks

It could be the noise from turbo when it starts to spool up.
