Here's one of the threads, don't know if it's the same issue you've got but might be worth a look...

Holy F man that can be it!!! It always happen to me around 2900 rpm but it really sound like this. Thank ALOT for the share, it is really feeling like it is coming from the rear rocker box. I will definitely look inside soon.

It can take a lot of logging runs to get all the pings out, and even then it still may happen from time to time. I've just accepted that all Harleys will ping sometimes. Light pings where you don't actually feel any power loss aren't the end of the world and aren't going to blow up your engine. The ECU will temporarily retard timing when it detects pings.

One thing that really helped mine was to retard timing across the board based on intake air temp. On a hot day where you're not moving very fast your intake air temp can easily get up to 150F or more. Pinging always gets worse the hotter it gets. Using my powervision tuner I increased spark retard more aggressively when the temps start to rise.

Nop no sound was heard during the dyno runs. My tuner even rode my bike for a run and he didn't heard anything. He told me to stop seeking for weird noises and ride the **** out of my Harley haha. Im just a freak.

This is so true... I wear a full face helmet, and hear protection as well. I've spent too many years on load machinery and in front of loud amplifiers, so I try to preserve what's left!

But occasionally I either forget to put my plugs in, or leave them out for a short hop and the bike sounds COMPLETELY different!

Oh hell yea, I couldn't ride around the block without hearing protection. The last time I did I wanted to park the bike in the driveway, pour gasoline on it and light it on fire to cast out the demons...
