    What happens when the chain breaks? It knocks a whole in the casing? Can it hurt the rider as well?

    Are there any signs that a chain is past it's due date?

    What is the purpose of the chain rollers exactly?

    On drag motorcycle must have chain guard past axle. Theory being it break, come up and whip you.. Rollers guide chain at Max suspension travel.

    With chain properly adjusted, if you can pull chain away from sprocket at the middle it's worn. I also see how much side way bend.

    Highly recommend replace both sprockets and chain ass a set
    Remember, good isn't cheap, cheap isn't good

    So what happens or what's the down side of not having the top and bottom chain rollers installed?

    You would have slightly less chain contact on the sprocket which at full compression could allow the chain to jump off, especially with smaller sprocket, worn sprocket or chain, or loose chain

    Manufacturers usually don't include unnecessary parts.
    There is a thread on how to change over to a Banshee style roller eliminating the pin style roller.
