1) Tappets - adjust to suit and/or chain guide/tensioner if one

2) Brakes - Worn rotors I'm guessing

read the top mate new BRAKES

This may sound a bit weird, but I had a similar noise to yours. It ended up being the retaining clips that hold the lid of the air filter on. I had tightened the wing nut a bit too much, leaving the clips loose enough to rattle. Although, my noise was fairly constant through the revs. I felt like a right knob after I worked it out haha, thinking it was something bad.

Just thought I'd share on the off chance it was that, probably not though.

Sound alot like a Brocken bracket for a steel pipe sort of like when you have a Brocken exhaust bracket try feel around the engine bay for the vibration
