My bikes been making a rattle/tapping noise. It's quite noticeable at idle but once I give it a few revs it speeds up according to what rev range I'm at. When revved the rattle does quiet down but can still be heard if I listen closely. Not sure if it'd be a factor but the bike has VVT.. also all fluid levels are sufficient. Here's a clip of the sound at idle. Any help would be appreciated. Cheers.
