I have a oil pressure reading of 3 to 4 lbs at idle when hot and idle at 1200 rpm and a pressure of 27 to 29 at highway speeds. It is a 2002 twin cam classic. Is this enough? Thanks

Sounds like the Spring on the pressure relief valve is weak .. Harley recommends 10 PSI Minimum at Idle, 30-36 running and 44 at Initial Start up
