It could sound very bad when it runs. It will sound like a grinding or rumbling or rattling sound when it runs.

If it gets very bad it will seize, that is just lock up and quit turning. Dirt bikes have tough lives, and if they get mud or dust in them the bearings in the crank and big end on the rod will start to sound bad before they lock up completely.

And you can hold your ear up to the engine when it is running, if there is a ticking or knocking sound coming from the cylinder then that is just the usual wore out piston noise, if there is a rumbling or rattling sound when it runs coming from the bottom of the engine that is the crank or rod bearning.
