Default Engine Ping - What is It?

My bike makes a high pitched squeal during hard acceleration. I can control the sound with the throttle. I thought it was the belt or something. A harley tech test drove the bike and said it was engine detonation and that the bike needs to be tuned. Is that the sound people are refering to when the mention "engine ping"?

If it is ping mine has been doing it for about 2,000 miles. Will it damage the motor?

Since when does a ping make a high pitched squeal? It is usually a rattling sound not a squealing sound, or so I thought. And yes if it ispinging it will eventually damage the motor.

Personally.........Id love to hear a good, detailed description of "pinging"...mine sounds like it "clatters" sometimes.......but it has since Ive owned it and its been driven by a couple of techs who were really impressed with the way it ran. No mention from either of them about pinging.....

A high pitch squeal is usually induction related. Could be an air leak somewhere. Pinging or detonation sounds like a high pitch knock or rattle. How did this guy earn the title of tech?

I only have this problem when the temps get up around 230 and wack the throttlearound the 3K area. Haven't had a dyno tune yet and leaned out the fuel in the cruise area to get better MPG.

UPDATE: I turned on the accelerator pump function on my PCIII...no more high pitch ratchety squeal, better throttle response also.

Now lets see if my MPG stays between 37 - 41?
