Clatter!!!
2013 wide glide, 103, PC-V, Stage 1, Map by Fuel Moto, H-D syn oil all 3 holes, 3400 miles, 35-43 MPG.
I am experiencing a rather loud clatter when when my engine is fully warmed up. It is present at all rpms. It's not pinging(preignition) and does not sound like lifters ticking. Sounds more like clacking. Like smacking two boards together. No problems when it is cooler out, ( it runs like a bear @ 50 deg F) but very pronounced when the engine is hot or under load.
I did not have this sound until I started running Syn oil. Oil pressure is 30# cruising and 7-10# at idle.
Is this common for syn oil? I ran dino for the first 2k miles and had no problems. Tuning? Or is the bike just giving me a standing ovation?

If the noise started when you changed the oil, try another oil and see how it sounds. Even another synthetic may work better. Don't get stuck on the HD kool aid.
If it still persists then you can look for more expensive, mechanical reasons.

I have noise too...spent time and money replacing lifters, pushrods, etc.
Does not matter what oil...I settled on Mobile1 synthetic 20w50. I just ride the **** out of it now and ignore the ticking. these engines are easy to work on so if it blows I'll build another!
My brother's bike has basically the same build as mine and it is quiet as can be.
My point is, what works for one may not work for another...you have to try and see what works for yours out of all the suggestions.

Don't want to beat the oil subject into the ground too much, but I've been through this with multiple oils. HD oil is garbage and one of the worst offenders. HD's label on citgo oil I believe is the manufacturer of it. I've done this song and dance and is how I came to liking of the oil I still use today from long ago. I literally went through this same thing after using Syn3. AMSoil did the same exact thing. Clackity clack clack. Harley will tell you Synthetic doesn't have sound "deadening" agents in it as Petroleum oil does. Weird, because I changed that garbage out and went to a different "non sound deadening agent" lol synthetic and all that racket when away. I found what I like to run without a lot of trial and error. Explore your options. There's a lot better ones out there.

If it's louder under load, that suggests it's not the valvetrain. Since it's not present when cold, that suggests it's not piston slap from a loose piston.
Have you checked for exhaust leaks?

I changed the oil today to 50 wt and checked for an exhaust leak. No leak. Still sounds like it's coming apart! Collapsed lifters? I would guess tuning, but the plugs look OK. It's got me stumped.
