    Chain tensioner not working

    I just noticed this but my chain tightener/tensioner isn't on right. The tube it's on isn't shaped right so it doesn't fit on correctly. We positioned it so it doesn't jam but every now and then there is a loud pop coming from the chain. I believe it's because the chain is coming off the...
