I have a 2016 flhtk. The oil pressure worries me. Hot it has 13 pounds at idle. Days the air temp is 70 to 80 it runs about 30 to 32 at 2500 to 3000. It never goes above 36. Maybe 38 psi. On really hot days like 100+. I have seen it down to 20. Funny thing I can pull in clutch and rev it to say 4K and it will go up to 30 and stay there eventually drop back to 26 27. I took it to the shop they tested it with manual gauge said it was within specs. Said my gauge was off some. What do you guys think? Could this be a faulty oil pressure sensor or weak pressure spring, pressure valve or just normal operation. By the way running Mobil 1 20/50. Bike has 23k on it.
