This kit works in conjunction with our Seat Tube Motor Mount p/n 12416 and Seat Tube Jackshaft Kit p/n 12419. Two brackets in this kit bolt to the back of our aluminum motor mount. The sprocket idler (#35 chain sprocket) bolts to the boomerang bracket and is adjusted with a tie rod using heim joints. This is a bolt-on kit that takes just a couple minutes to install. See how we use these kits on our Smoking Loon 212cc bike. https://youtu.be/uyuMclcIu3U
