Engine noise KTM SuperDuke 990 - 2007 - Solved

My KTM Superduke 990 -07 has developed an engine noise that I can't identify. A theory is that it might be the oil pump, but I'm not sure.
Checked the cam chain tensioners, they seemed ok.

*Solution*
Even though they seemed fine at first, it turned out to be the cam chain tensioners after all. After I replaced them the noise disappeared. Unfortunately this also is a sign that the cam chain itself might need to be replaced in a near future.
