Recently bought an 03 Cbr600rr with around 21k miles. It runs like a champ but a while back I noticed it started making this high frequency buzzing noise underneath the exhaust tone when I’m riding. I figured it might’ve been a loose fairing or something but it also made it in neutral sitting still. It also started making that clattering at idle and when letting off as heard in the video. I swapped a manual cct into it and adjusted it as well as I could and the noise hadn’t gone away. It had been sitting for a while and I hadn’t done anything to it and I started it today and it seems like it’s gotten worse.
