Oil fouled plugs on a fresh rebuild could also be from excess oil left in the cylinder bores when you assembled it. I always wipe out the excess with paper towels.
Oil in the sight glass will be foamed up. That's just clutch action causing that.
Oil ring problems generally cause heavy blue / grey smoking. If wave ring is overlapped, it will blow oil droplets right out the pipe.
What carbs?
Pods or airbox ?
What jetting is in them?
Is it a vacuum petcock? Are you running it on PRI position?

I bought in 1991. It had sat for many years. I fixed it up, and it was a nice bike that got me thru college. When I got "employed", my dream was to make a street rod. nothing crazy, just wake it up a little. I tore it totally down, and rebuilt it with the following.
1075 kit; web 218 cams; Keihin 29's; and head work from Cope racing. I put it back together in 1998 and rode it (joy-riding), unitl about 2004. It never ran as "streetable" as it did before, and I was disappointed in myself for messing with it. Family situration is different now with kids older, so I was determined to resurect it, only this time I was confident, with much more info on how to do it right, that it would run just fine on the street. Looking at whats on the steet these days, I didn't do anything too radical to it. So upon tearing into the carbs, I found that the jet needles were wrong. the needles were stamped with P151, which didn't match anything I could find for those carbs. The pilot jets are also 1 size too big for some reason. Ordered the correct needles from Sudco, along with float valves that were ruined, left the pilots the same for now and the carbs were ready to go. I was totally confident that this, along with dbl checking the initial cam timing, woudl fix my problems. And thats were I'm at now. Totally cluesless how the bike is now magicaly spewing oil. I don't have a way to check oil pressure - I thought that might be too high, but the filter is fine. What else could cause high oil pressure ? The bike would seem to get hot if I ran around slowly in town too long, so I planned on getting an oil cooler this time, but never got that far.

When you changed the jetting, you have ran it around some, although years ago? Could be that when sitting, depending how it was stored, that the rings are a bit stuck.
I would be sure it is oil, and not fuel. Did you change to fresh gas? Check the fuel levels in the carbs with the Clear Tube Method, and see if the level is correct.
How is the spark quality?

...bike is now magicaly spewing oil...bike would seem to get hot if I ran around slowly in town too long....
Some reasons for over-heating:
-- Oil level too high or too low or wrong viscosity;
-- Ignition timing maladjusted;
-- Advancer sticking;
-- Fuel mixture too lean.
Would also sniff-test crankcase oil and examine it to determine any possibility of fuel contamination.
Good Fortune!

I do not believe you have stated what size, main jets or pilot jets, needle position. (may of missed that?)

"I have redo the cams, and I have the same basically the result. The bike will start fine with the choke on. Then idles down nicely when I turn the choke off. It will run smooth and nice - for about 15 seconds, then grayish smoke starts to come out the exhaust, it begins to bog down, and stalls. The plugs are oil fouled, and the oil in the sight glass on the clutch cover is all foamy."
So this was on going before trying to adjust the cam timing?
Also when was the last time carbs were cleaned out really good and the slow/ pilot circuit was blow out with carb cleaner and compressed air?
What oil is in it, some thing high detergent?
If you tell what your set up is, like suggested, What carbs/ pods or airbox/ exhaust/ etc.
These guys can tell you most likely what will be spot on jetting.
