Should attach tothe cam tower immediately behind the cam gear. Takes a 10mm allen to remove the bolts. When affixed tothehead, the opening should be toward the right fender,which allows for infeed and outflow of the new and old chains. It has a close fit which keeps both sides of the chain in contact with the gear.
