My '87 R80RT has 80k miles on it. Been maintained by the book since new - I'm the 3rd owner. Running Castroil 20W50, after having run Amzoil for a couple years. When the bike is up to operating temp, at idle (1,000 rpm), the oil pressure light flickers. Higher engine speed, no flicker.
Is there an easy way to determine if this is caused by oil pump vs worn bearings? What else would cause this?
Oil level is full.

Oil Pressure Woes?
There is therefore now no condemnation to them which are in Christ Jesus. (Romans 8:1)
Re: Oil Pressure Woes?
It might be the oil. Those oil pumps hardly wear out. Thry running on a 20W-50
