Hi!
After setting the valves the the top end  makes that nice whispering sound from the valvetrain, but after a few kilometers she starts to make clattering noices from the top. More from the right side. When u slow down i gets worse and goes away when opening the throttle. Worst case; camfollowers are grinding away together with cam....

Any advise?
 
Check them again.
Check that the adjusting screws haven't dug into the valve tips giving larger clearance than your feeler gauges show.
You can use a torch in the adjuster cover to see if the cam lobes are scored up but that shouldn't happen so quick, unless you have no clearance.
Check your exhausts and various bracketry as it might not be inside.
