New chain. If I turn the cranks by hand it is silent and smooth. Once I am on the bike, the drive train is very creaky / noisy whilst pedaling forwards (backwards is smooth/silent).
I have not pedaled more than around the block.
I am guessing this is simply from wear patterns on my cog/sprocket. Will this remedy itself after I put some time on it? Anyone have experience with this? I have never had a problem putting on new chains on my set ups in the past. I don't want to destroy something, but at the same time I cannot afford to shell out a bunch of money on my drive train atm.
Tried 2 new chains. New bearings in bb. Not to tight. Lubed.

1 - Is the chain upside down?
2 - New chain - worn in drivetrain. It will take some time to wear in, but it will happen.
The tooth spacing changes on the sprocket just a bit as the chain is worn and stretched.

Do you have good chain line?

Chain line is good and the chain itself is installed correctly.
The build itself is over 2 years old. I usually change my chain out at the beginning of every spring. However, before doing that, I snapped my current one.
I managed to find the left over links and pieced together my old chain. It works fine (around 15-20 or so new links of 38 + half link that make up my chain). The new links don't see to be causing the same issue.
I expect some creaking/wear in when putting on a new chain. However, this was a bit over the top and even pedaling to break it in felt wrong.

I had the same, extremely loud. Turned out it was my driver worn down in a shuriken shape.

Did you possibly mix 1/8" (4/32") and 3/32" chain links?
The leftover links were definitely from a singlespeed chain? Not a chain for geared bikes? They can be narrower, and therefore not as good for a bmx sprocket.

You'd have to be pretty blind to put a BMX chain and a geared chain together.

What a helpful post. Good thing you were here

At least I stayed on topic. You're just highlighting how much you want to suck me off. Again.
