If you are replacing with chain driven cams and not gear driven, then you need not worry about crank runout. Ask yourself this question. What am I going to do if I don't like the amount of runout? Nothing, unless you are prepared to tear down your motor, true and weld the crank and put it back together. Costly, time consuming, and unnecessary if all you are doing are chain driven cams and not a triple digit HP and TQ screamer.

If your run out is more than .012" and your bike is under warranty then you can get it fixed under warranty...other than that just ride...I know mine is out but i don't know how much. I jst ride....

You don't do the damage, the damage (if you want to call it that) is already there... but the chance that it's more than .012" is unlikely...That is what MOCO is banking on..They have determined that this is enough of a gap for the bike to run ok with chain drive cams...it use to be .004" and that was probably costing them a fortune....Someone with more may add to this...you can also youtube harley crank runout measuring...

Here we go.....LOL
I spoke with Fuel Moto this afternoon about their cam choices for my setup and riding style and so on......
The guy I spoke with (not Jamie or Keith but very helpful) recommended either the TW-222 (Heavier bike, riding 2 up, passing power and pulling a trailer) or TW-555 (He described these as a higher performance cam). He said the 222 would come on at around 1800 rpm, start dropping off around 4000rpm and the 555 would come in around 2500 and drop off around 6000rpm.
Looking at the dyno charts on their website with similar setups as mine both cams hit max TQ at 3000-3500 and begin to start dropping off a few hundred rpm after that. The HP is still climbing on each. It seems the main difference is where the TQ comes in, with the 222's torque is at almost 100 ft lbs at 2200 rpm and the 555's are around 70 ft lbs at the same rpm. I definitely not trying to start a debate or open a can of worms on this issue. I just need to figure out which one will be the best choice for me and my riding style.
I rarely ride 2 up, do not pull a trailer and can easily pack all my belongings in the saddle bags and tour pack with no need for additional luggage. I have never had my bike above 4000 rpm and the 4000 came only in a dangerous merging situation. I usually shift around 3000-3500 and cruise 2400-3000 rpm. Decisions Decisions!!!!!!
I'll be ordering the cams Friday (payday) so I have a few more days to research and make up my mind.
Thanks for all the help!

I'd get the 555 since they will still be good when (not if 
) you decide to get the heads worked and bump up compression...
Either will make a big improvement over stock, but the 555 is more versatile IMO.
