yeah thats wy I mentioned it, if they can't manage to keep enough press fit on the bronze bushed rod ends to keep them from spinning, why should I think they will have a good press fit onthe wrist pin and if it gets loose it slides to the wall without a snap ring or poly button.
Hard to beat those old 300 Ford and 292 Chevy 6's, those rods take some abuse, bottom ends are bullet proof. Got the 292 in my 63 truck, 15 yr old grandson just learned how to drive the manual shift 2 weeks ago. Good thing he had that torqy 292 to help him learn the clutch part although he did manage to kill it a couple times taking off on a hill...

The rod in my attachment is a non bushing press fit pin out of a 4 cylinder iron duke GM that was in a lot of front wheel drive cars back in the 90s. It had overheated from a stuck thermostat. I rebuilt it totally. After it over heated, it would start knocking after it warmed up. I discovered the piston on this rod had been slanted in the cylinder since new. When it overheated it warped the cylinder a little and when it heated up it was dragging on piston. It also put hairline cracks in the cast iron heads. The long scratch marks are were I pressed out pin, but most were already there from were GM pressed in in when new. That circular area is were the bore did not clean up when GM machined it. They sure missed this one but it never made a sound for 100K till it overheated.

Very similar to the mileage timing of when my issue started. Your sound description matches what I am hearing as well. It is just more constant now kind of like the sound the spinning wheel on "Wheel of Fortune" makes if the clicker thing was metal.

since about 5.5k the noise has been at every startup. at first I missed it since I usually pull the bike out, crank it and walk back into the garage and let it warm up for a few minutes. I always heard a little clattering on startup but with the 12 inch yaffes and the poly riser bushings I always thought I was hearing the clutch lever rattling, which I was, but that wasn't all it was. now it's very obviously an engine noise. had the comp changed last time I bitched about it at about 6k miles and was told that it was wearing excessively. sounded good when I picked it up but it was warm and I only hear the knock on startup when cold. it sounds like rod knock in any other engine but it seems to sound like it's in the bottom end of the motor from the front of the primary. I guess final teardown will reveal the true culprit once and for all.

I had a problem in my '12. Ended up finding some metal fragments in the motor. Harley sent them a fresh engine to replace it. Was at about 10,000 miles.
They were very fair about it. Promised me nothing until they looked inside it with a scope. Believe it was with a certain run of motors.
Still have some top end noise. Got rid of it by removing cats. Now just loud enought to not hear the valve noise, but quiet enough for freeway cruising.
