My bike pings with not so fresh gas in it or Non "Big Oil" company gas bought at a local or traveling out of the way Mom and Pop that goes through one tanker every 6 months. I found that out on a recent trip where I was on a hilly winding out of the way road after a fill up on a hot day and could hear it pinging away which just caused me to shift more. Biggest difference was startup as it would burp out intake or backfire and send everyone running for cover, next tank of fuel all better. I am stuck running 91 non ethanol most of the time and occasionally 93. I can feel the difference with the 93, much better response and easier starts.

I have a 2012 Road Glide Ultra with the 103 and have delt with the same thing for years and still cant find an answer. I've used different tunes, always use 93 octane with no ethanol ect. It only does it after the motor has warmed up and getting a good throttle pull, does it in all RPM ranges as well. I've learned to live with it and be a little less aggressive on the throttle.

Just for reference what sort of performance mods have you done? I wonder if slightly retarding the timing in the affected rpm and throttle range would eliminate it? I never had a 103 but have an 88 carbureted and used to have a 96 both at stage one and never had any pinging from either one even when hot.

Mine was all stock except for RCX slip-ons when I got it,. I have since added Vance & Hines Dresser Duals, Stage 1 air cleaner and still it pings exactly the same as it did stock. I have a Power Commander V and I've tried a few different tunes but it still pings. I just completed a cam swap, new lifters, Rocker Arms and Rocker Lockers so we'll see if there is any changes for the Ping this spring.

So finally got to put a few miles on the bike this past weekend to try a few tunes out after all my winter projects. I think I finally found one that I like and is real close to all my upgrades. Had a few days in the 70s so not super hot yet but so far I haven't noticed the ping! Im really starting to think it may have been running a bit too lean when the engine gets hot. Once I get a chance to really get the motor hot, I'll confirm if its actually gone or not.
