I was sitting on the floor beside my '18 Sport Glide and noticed for the first time that there is a quiet ticking sound coming from the left side of the engine. The engine was off and cold, and I've checked several times since then (like just now) and it's still there, like a clock in regularity. In fact, if it had a mechanical clock, I would assume it ticked at 3Hz and think nothing of it. I can't hear it if there's any noise around, or even if I stand up. Not sure if it happens when it's running because it's too quiet to hear. Also not sure if it was happening all along. Any ideas?

 

It senses and registers that there is a key fob in the area.

 

Hey, cool, thanks!

 

Try it without the key fob in your pocket to see if I am correct.

 

Is that a Delta Binaural Beat (3hz) ~ Pure..

 

Well, just back, read this, and went to see. No ticking without the fob, but then I got the fob and still no ticking, so maybe I'm losing my mind. I'll check it again later.

 

Well, no, just ticking, at about 3 ticks per second. Nothing that sounded that cool. I think if I heard that I'd be even more worried...

 

the old intermittent ticking thing.
might be a bomb.

 

Is this something often reported? I couldn't find reference to it, but it was hard to tell because any search about ticking came up with threads about top-end stuff.

 

It was a joke. Sorry, could not resist. You are overthinking it.

Modern vehicles are all controlled by computers. they do what they think they should do. Static electricity, temperature changes, humidity, lean angle,
funny smell in the room, there are a lot of unknowns that cause intermittent clicks, whirrs, pings, noises real and imagined.

You tried to duplicate it and had unreliable success. You are overthinking it. Just ride it and let the magic happen.

No, I have not heard of any bombs mentioned in any service bulletins.

Edit, Now I am reminded of a funny noise from under the seat that turned out to be an onboard air compressor in the aftermarket seat. Just an example.
and this reminds me of a ticking around the top end of my Road King that sounded like a panhead motor cooling. it want away and never came back.
(the seat noise was not my seat, just some mystery solved by asking on this forum. do not give up, someone might yet solve this puzzle)
