noise from throttle body

have a xl700v with an annoying sound. anyone with any ideas on the following sound issue? the reason I'm trying to figure this out is that I've never had anyhting like it on any of my previous bikes (xl600v, sv650s, f650gs)

Ticking/clicking/rattling is somewhat hollow, more like a higher pitched dakadakadakadaka or drrrrrrrrrrrrrrrrr
It only happens between 2500/3000 to 4000 rpm
On all the gears at the range (3000 to 4000)
I only rev like a millimeter
It lasts only about 1-1,5 seconds
If I rev another mm it appears again for about 1-1,5 seconds
It's higher pitched then the deeper normal dakadakadaka sound form the engine
It sounds like it's coming from the top area of the engine
I can reproduce the sound at idle, but it's harder to do, it's less pronounced then and don't last the full second. It's quite/very pronounced when driving
It only happens when the engine is properly warm. Doesn't happen the first 5 minutes of driving.

sounds pretty much like this at 0:21 and 0:23-0:24 - most like 0:23-0:24
