What kind of fuel is everyone running?

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.

In my 09 FXDC I use 92 octane. It still pings bad on occassion. I'm not real happy with Harley's work with their electronic engine control. I've brought it to the service manager's attention and dont really get the impression they can do anything about it or want to. It pings on occasion in closed and open loop, more so at lower rpms. The service manager says dont run it in those rpms, I laughed at him and asked him if he were serious. I'm getting ready to start tuning this thing myself. I've been around the block with speed density and know I can do a damn better job with a wideband and some good tuning software then they can.

Great responses! I'll have to ask my buddy why he's running the regular stuff when I get back from the beach
