Has anyone else noticed this? It's a high frequency metallic jingle sound, like a metal clip or loose washers that is ringing all the time. It changes momentarily when I hit a bump and it gets louder at certain engine revs, a bit like keys on a key ring but a higher frequency (no I don't have keys in the ignition, just the one bike key). I usually notice it a lower speeds when I ride past something that reflects the sound back my way. I think it is from the left side of the bike. I looked at the shift linkage and the front sprocket but can't find anything that would cause this sound.
