I have noticed that my oil pressure is not as high as it used to be, could this be a problem?

I have always used the same oil and weight (castrol 20W50)

My oil pressure cold used to be 65-70 idling, now its 45-50 cold. Hot after riding at an idle it's 20 and riding 4000rpms it's only showing about 50 were before it used to be 60-65. It still runs great, no shaving, and no other problems.

Should I be worried about this?


Thanks,
Cam
