As with previous efforts a few revisions to the chain routing was required to keep chains from jumping off the sprockets. Sprockets need to align in two dimensions. First, in a straight line running parallel with the chain. This alignment is pretty forgiving. Second, centering the sprocket on its shaft. This second alignment is far less forgiving. With longer chains, any up and down movement caused by an off-center sprocket quickly sets up a whipping motion that throws off the chain. Nothing a couple of added tensioners can't fix though. |
