What is the bolt called that holds the chain tensioner wheel to the chain tensioner bracket? I made a really cool homemade tensioner, I will post pics and directions when I get it up and running. Should be way better than stock. OR...has anyone replaced the stock P.O.S. chain wheel bolt with something else that works? For my new tensioner I need a longer bolt..just don't know what to ask for or if anyone had created their own. Thanks, Dave.
