My average since I purchased my 2010 WG new at the end of April, taken from 20 samples is 221 degrees. However it has slowly creeped up to the latest sample of 247 degrees. I don't know why but I have 2500 miles, changed to SE synthetic at 1000 mile change, installed Samson shorties, SE ac and had the HD dealer do a modified map download. Bike runs strong and smooth but temp has creeped up over time. Now looking into oil cooler to see if that helps.

Steady state on mine yester day at 95-100 degrees outside and 70-75 miles an hour was 245-250 degrees.
Running a 103", 10.5 compression, Wood 408-6 cams, ported heads and a Harley oil cooler.

A 'good' synthetic will hold up past 300* without breaking down. Syn3 is a good oil but it's a Group III oil made from hydrocracked petroleum base. Amsoil is a Group IV oil made from PAOs (polyalphaolefin) and Mobil ain't sayin' but I'd bet a case of beer that their Mobil 1 V-Twin is a Group IV as well. I'm 99.99% certain of that.
I would say -- Anybody that is consistently running oil temps above 220* should give serious thought to an oil cooler. Even if you're in an area where you'll be riding in temperatures below 40-50* sometimes, the HD cooler has a thermostat on it, so shouldn't be a problem.
They say our engines aren't air-cooled, they're "prayer-cooled." And while you can get away without an oil cooler for a long time, just think of the effects over heated oil can have on the guts of your valuable and powerful engine through the long haul. A lot.
