Wondering what oil temp this thing should run at? Riding this afternoon withouside temp around 75 degrees. Just riding easy at 55-60 mph. Seems hot at 250 degrees. Any ideas

Fine, ride it and don't worry.
FYI synthetic oil will extend the oil life at elevated temperatures.
Guys that live in the desert and have ambient of 95+ often see in excess of 275°F. Just a little more frequent oil changes for those extremes.

Thanks just seemed hot because the ambient wasn't that warm and I wasn't using any boost

I can only assume with that much going on you have cooler(s). If not get them and a Baker +1 oil pan is another good investment.

no coolers other than the intercooler. Just got it back from shop no oil pressure. Cam plate came loose. Fixed and pressure was good. Rode about 45 miles today in 82 degree heat. 2 lane road used no boost 2600-3800 rpm. By the time I got home 269 degrees, 5 lbs oil pressure. Almost like the hotter it got the lower the pressure. I'm scared to ride now. 12,000 miles on the build new issue nothing like this before. It's running hot when it shouldn't. 50-60 mph down the road it should cool down, just gets hotter.

You should check for sumping first before jumping to any conclusions. I suspect the cam plate ordeal was doe in less than good fashion.

Bolts just came loose and lost pressure. What's sumping?

When the oil does not get returned from the engine case to the oil pan. This causes excess pressure in the case and an extreme loss of power. Typically it's caused by the oil pump not being installed correctly.

Got a suggestion as to a course of action?

What is your hot oil pressure at idle? At 3000 rpm?

FWIW,
Service manuals state up to 60*-20W-50.
60*-80*---------------------------50W.
North of 80*-----------------------60W.

At 269 degrees at the end of the 40 minute ride yesterday morning pressure gauge was flashing at 5 lbs.  I did a few slow revs to 1800-2000 rpms and it went up to 16-18lbs. Seems very wierd. Getting scared to ride it!

Not aware that anything has changed with the pump. As far as I knoweverything was fine with the build up until a couple of days ago when it lost oil pressure and the shop found the cam plate loose. I believe the build has 12-14k miles on it. Just bought the bike a few weeks ago.

Do you know what cam plate and oil pump were used in the build?
What was the hot oil pressure at idle and 3K before the cam plate came loose?
Did the shop just tighten the plate down or remove it to be sure the oil passage O-rings had not slipped out of place while it was loose?

when she lost oil pressure last week she seemed a little hot but not sure. Shop checked the gauge and the sending unit and they were good then pulled the cam cover and saw that the plate was loose. Did inspection and re assemblied with new bolts. Then came yesterday with the issue with the temps being so hot (270) and 5 lbs at idle. You could tell she was hot. Not sure where all that came from. It was just a nice easy ride with no boost and moderate rpms.  I did go home at lunch and fire her up cold and had 42 lbs at idle.
