What kind of fuel is everyone running?
I have been running high test in mine since I bought it but then again I have used the highest octane available in all the bikes that I have owned. I noticed one of the guys I ride with putting regular in his RKC so I thought this would be a great topic for a poll.

High test when temps are over 90.
Mid range fuel when temps less than 90
Running 10.5 compression, a little higher than stock.
No pinging issues whatsoever and I would doubt, that if tuned properly the relatively low-compression stock aircooled Harleys would have any problems running on mid grade fuels even when over 100 degrees outside.

I know this is against what the owner's manual says....but I run the 87. I tried the higher stuff and it really made my bike "rattle" and sound horrible. My riding buddy only uses the 91 and he said he gets the opposite result than me (says his bike really "pings" with the 87). I even tried alternating tanks with the good stuff..........result was the same. I'm sticking with the 87.
