I just put a new sprocket on this frame, and its bolt drive. When spin the cranks, the sprocket is uneven when it spins, is this normal?

It sounds like you are missing your sprocket adapter. Did you forget to install it or do you need to buy one? Does your sprocket fit snug over the spindle or is there a gap in between?

This is a sprocket adapter, sometimes called a top hat washer. When your sprocket is bored for a larger spindle than the one you are using, a sprocket adapter is inserted into the sprocket so that it fits snugly on your spindle.
