I doubt it's a rod, specifically because I don't get the knock under load or really anywhere above idle. I would normally think a rod or crank bearing knock would be under load or with the engine turning faster than at idle, right?

(and really, it's a very slight noise in the grand scheme of things, almost unworthy of being called a proper KNOCK, but it's more of a knock than a tap or a click, so I call it that)

I've seen it both ways with rod/main bearings. Some get quieter when rpm picks up, some louder. No doubt oil pressure plays a role.

I'm not hearing much of anything that I don't hear in mine, or most of the others with stock pipes I've listened to. I think mine makes the same noise you are concerned about, and it hasn't changed in five years.

These things make a scary amount of noise through a stethoscope. I always thought it would sound like hell if all that got out of hand. I think the constant hiss must be the timing chains running on the guides or tensioners, or maybe the chain roller wheel.

That makes sense. It doesn't seem like an issue when I'm riding, it only bothers me when I'm idling or listening to it at idle and TRYING to find noises. It's had ticks and clicks ever since I got it 8k miles ago, my dad even commented on that when it was not earshaved and said "I like your bike because the engine makes a lot of noise, like mine" (He has an '05 Heritage Softail with the Twin Cam motor).

I'm not in any kinda situation to tear down a running motor in my back yard, or lug it upstairs into my bedroom to work on it, so for now I guess I'l err on the side of ignorance and see how long she keeps on running. Oil light doesn't come on, doesn't overheat, and the oil isn't due for a change for another few hundred miles.

Even if it does die, I could stow it at my dad's garage down in Orlando and work on it over weekends or whatever, or grab a cheap CL parts bike and swap motors, but I'm planning too far ahead for something that only worries me when my anxiety is flaring up, but has been a fear in the back of my mind for well over a year now. I think I said to myself one day "you could let it sit and not ride it for fear that someday it may break down, or you could ride it and see if it ever breaks down. Which path would you rather take?"


Thanks for listening to the ramblings and engine of a madman! hahaha
