Wow, thanks for all the great insights. Really appreciated.
Paul, no... there's been no increase in lifter noise, so that's reassuring for me. In fact, I changed the spark plugs and, with the fresh new oil change, the motor has never sounded smoother/quieter.
I'm not familiar with how to do a manual reading of the oil pressure, so I'll take it to the stealership and see if they can give me a manual read. Thank you ALL. .

However with the no oil light when the pressure reads zero, and a smooth, quiet engine.... I'd just ride it... If it starts to make unusual noises, I'd investigate further..

Also need to keep in mind when reading, is I believe they changed oil pumps, guessing with 96" My 88 and 96" have different values, 88 reads higher.
If you are pushing 60 psi when cold, that makes me wonder if gauge is working. I don't know how gauges work. I just basing that off at times it reads high
Mechanic friend of mine scuff at gauges, says you will hear lifters. But that is not to say it cannot be tool.
If it reads high cold, and then goes low when hot. I would be thinking about this. It implies to me the gauge is working over a range of PSI. Again I don't know how gauges work.

Put a new sending unit on it. Not that hard to do. A little awkward maybe. Ive had one fail before. Showed low on gauge. It only takes 2 or 3 psi to make the light go out. Gauge itself could be off that much. Or swap in a mechanical gauge for a test. Watching a gauge read zero would bug me even if I knew it wasn't actually zero.

The oil pressure on my 03 Ultra was very low at warm idle. At 30k I had the SE Cam Chain Tensioner and oil pump upgrade. The pressure goes up 10-15 psi across the board after that. Engine was a humming dynamo after that.

Rounders, I bought my Ultra new in 2005... the gauge showing a drop in oil pressure to zero at stoplights (after the engine is warmed up) is new. This started happening about a month ago following a four-hour day trip.
