Strange sound. Need info/identification Video Linked.
I am getting a strange sound from my PE. Upon revving, as the RPMs fall away from peak of the rev I hear a grinding-ish sound coming from the exhaust. I don't remember this being present until today. Please listen to the video and tell me what you think. This didn't seem normal compared to other PE sounds. Make sure to listen until the end as it is highly exhibited on my last example rev in the sequence. Thank you!
Yes, the scraping/airy sound onnly present briefly when the revs fall from peak of the rev. Normal/bad? I know it wasn't like that until I noticed it today.
