So thats what life looks like if you are a rear cylinder on an Ironhead.
Sounds chain/sprocket related to me.

Lift the chain off the tensioner and spin the roller. It should spin free and without noise and without any notchiness. if you can feel any notchiness when you turn the roller, the bearing is toast. But that still might not be your noise.

I just fixed a similar noise and it was the chain rubbing the inside of the sprocket cover.

seems to occur when the rear wheel is turning, I'd get it off the ground and spin the rear wheel without the engine running, should be able to isolate where the sound is coming from easier.

do you have a bolt in this location that the chain is catching on:



it may only catch when you are under load. I have to grind some clearance off a regular grade 8 bolt not the hex head pictured which is obviously sticking out too far but this is what was used when the bottom end was rebuilt for me and if I wasn't paying attention I might have assumed would just fit in and not switched out.
