Welcome to the Two Wheeled Texans community! 
Feel free to hang out and lurk as long as you like. However, we would like to encourage you to Bought this along with some boots on Ebay and have no idea how to put the two together. The only other thing it came with was a string, like a shoe string. Asked on a few street based forums and nobody knows.. figured some dirt riders may know how this works.
Maybe a few pictures will help, string not pictured.. it looks like a shoe string.
