i think its exhaust shield

 

I think you hit it....

 

What pipes are you running?

I heard similar, and the front pipe was rattling on the rear brake pivot.

 

Its the shields. I have the same sound. its at a certain rpm. Crack the throttle hard past that rpm and u wont hear it. Can drive me nuts sometimes too. I loosen the shields clamps and re-tighten and the sound goes away for awhile for me. I dont think its pinging. 9 outta 10 times pinging happens under a heavy load

 

Thanks for the replies. I live in middle tn and the temp is in the 80's. This is a new sound. It's really amplified in 4th and 5th gear. Full throttle doesn't seem to do it. Maybe 1/4 throttle,enough to make the bike pull. I have the cheap cfr knock offs and sac. No download or tuner . I thought pinging would be from to much fuel and not enough air or am I backwards?

 

Backwards.

Lean condition will ping.

But I don't think that is your problem.

 

Im betting its clamps/heatshields

 

I'll give the shields a check tomorrow.

 

How many miles on the bike? Did the pinging start around 4 to 5000 miles?

 

If it is your clamps or shields they will vibrate like hell in neutral. So ramp up your rpm and see if it occurs, if not, I would be skeptical. Take it to the Harley dealer and let a good tech ride it..assess the noise. My money would be on Tucci's assessment..
