As a first step, you should carefully straighten any oil cooler radiator fins that are bent from road debris so you get the maximum cooling from the unit. After you straighten them, attach some protective screening to the backside of the V-piece to prevent future damage.
If you don’t see any improvement, it would be unwise to just continue to ride it knowing that the oil pressure is actually marginally low. The expensive consequences include failed bearings and engine seizures. There’s also an outside chance that the pressure sending unit is out of calibration. Hook up a pressure gauge to where the sender mounts. Evoluzione sells an inexpensive one.

The oil pressure should be as follows on superbikes:
cold idle - at least 2.5 bar
hot idle - at least 1.1 bar
3,500 - 4,000 rpm - 4-6 bar
