Man, don't need any more issues but that make sense - can I just lay a straight edge on the rotor to check?

Not sure if you are going to split the cases or not. If you are you may want to check the wheels in a set of bench centers. This gives you a true indication of run-out. If you check them in the cases the bearings may be hiding some of the run-out. If the bearings are taking up some of the run-out this will be transferred to the cases and the bike in the form of vibration. Also if you are building a BB with a lot of Torque, and you have split the cases, you may want to think about the Timken conversion if your bike is 2003 or newer. Some may think this is not necessary, but just my opinion.
I true a lot of HD flywheels for earlier HDs (pre pressed crank-pin) and the most run-out the I allow is 0.002 inches. Anymore causes unnecessary vibrations, and premature bearing wear.
Take the advice as you see fit.

I understand. I'm sure you will do what's best. If you do address it I'd be hard 'pressed' to get an S&S crank. I crack myself up. ..

How many miles you do annually? If you aint doin a bunch than Id leave it be. $1200 for an S&S crank and another $200 in gaskets, seals, O rings and bearings. Its easy to spend someone elses money....

And if that primary comes off might as well upgrade to the 2014 compensator and a Hayden tensioner. . . See how this works?
Soft makes a strong point. You told me you don't ride out of town often so a little runout shouldn't affect you with lower miles
