I have had a noise from my bike for a while now that I can't pinpoint and I am beginning to wonder if it is engine "ping" from running lean.
The noise is best described as a high pitch "chirp" that repeats in tune with the engine rpm that I can only hear when I am at a cruise speed (not accelerating or decelerating), and if there is something for the sound to bounce off of such as a median barrier or maybe a large curb. I can not hear it otherwise.
My signature states what I have, I run high octane always, and I understand the concept of engine detonation. I just want to know if that is what I am hearing or if it is something else? I have checked and tightened all the exhaust parts and replaced the rubber mounts under the saddlebags. No change. My tuner is supposed to, (and I have had it checked on a dyno to confirm it) put the motor while at cruise speeds at a good A/F ratio. Could it be a small fin or something left in my cat from being gutted that is whistling?
Sounds just like my 2012 was doing.
IF it does it at idle (mine didn't at first but by the time I found noise it was) then ck you upper engine dogbone\lollipop.
That was my chirp.

Does your bike only tend to do it when you know its hot, after riding for an hour or two not necessarily stop and go just over 80 degrees and you know the engine is warm. I know mine will do it with less than perfect gas (ethanol enhanced) and its hot. I have all the usual stage one crap and the bike runs good but once and while I have to let off on it to stop it. I know my Sert is working fine but I don't know the oil temp when it starts, I am leaning towards an oil cooler soon I suspect the heads are hot.

This does not sound like pinging to me. Especially since you do not hear it accelerating or under load

I honestly haven't kept track of it that specifically. My oil temps are normally 200-235 when I check.
I know my tuner is not the best and am thinking of just going with fuelmoto mapped PCV but would suck to spend the money and mate the tuner to the ECM and find out thats not it.
(DUC) - by doggone/lollipop you mean front engine mount?

See I was wondering if that was in indicator that it was pinging because with more fuel (acceleration) which would make it richer, the symptom stops?
Motor mount could also make sense if DUC was describing motor mount because under load I'm sure the engine has force on it and then under cruise its shaking freely in the mounts.

Ya that. Pinging sounds like a rock hitting the inside of a can, not a chirp. You'd know it if you heard it. The first time I heard it I knew what it was instantly. It will happen with the engine hot and under load like accelerating.
chirping is usually from rubber mount like motor mounts or the rubbers on the muffler hangers,could even be from exhaust notes,rienharts like to chirp.
