Strange noise at 7-8k rpm

When I get my engine to in between 7-8k rpm. It makes a metal on metal noise just for those rpm. It pretty loud, I can hear it in 6th cruising down the highway. Ive checked most the outer bolts and screws and they are all secure.
I am pretty lost here and dont have any idea. Any help would be appreciated. Thanks

When I hit around 8K I hear a loud metal vibration.

It turned out to be the clutch lever. If I accelerate real hard, I hold the backs of a couple fingers against the lever and it goes away.

I don't know if this is what you are hearing?

I have the same problem too.

I found that bracing the clutch-pedal with your foot helps eliminate the vibration.

It's a terrible noise. At first, I thought the engine was affected, but after several sound recordings I discovered it's not.
