So it seems like when I'm riding at a steady pace my bike is fine... all of a sudden I go to shoot across a street or climb a hill and I get down low and I hear a loud ass noise that sounds like something snapped ie. metal to metal. But it looks like nothing has changed, and im fine to ride on, but if I go to dig down and climb, or just haul ass it does the same thing... I'm scared that it will snap something. Some more info - My freewheel cog is kind of jerry rigged with some spacers and shit so that it will fit. Im running 45-16 and recently bought a sinz chain ring when i went from 10 spd to single, bought a heavy duty asshole of a chain, and had it put together at the lbs... anyone know what might be making this noise? -

You can find a very well written, detailed article about bicycle chain lines here
In a nut shell, the chain line is the straightness of the chain between the rear cog and the chain ring. For instance, with a poor chain line the side plates of the chain links will pull tightly against the teeth on your cogs and/or chain ring, and could create a all kinds of unwanted noises as a result.
Another possibility is chain tension. If your chain is too tight, the chain could be binding in spots, especially when under pressure. This is a pretty common source of popping sounds like you described, especially when really cranking down. -

The ability to tweak your derailleur position by tiny increments, in order to make the system shut the hell up, is one of the key benefits of friction shifting :-0 -
