Been working on my 1990 XR 100 for what seems like forever now. During my top end rebuild i have installed a BBR 120 kit. I finally to the point where i am installing the new cam sprocket and chain i purchased. The manual i have says to push down on shaft that rises up from the bottom half of the tensioner (tensioner rod) and then to tighten the tensioner adjustment screw and locknut. This is supposed to give me the slack that I need. I have the BBR cam in place but I am having issues with getting enough slack on the chain to where it will fit over the sprocket once it is installed onto the cam. If I do not push down the tensioner all the way and allow the thicker part of the tensioner to rise over the tensioner eccentric then I have enough slack to get the job done. I am pretty sure that the fat part of the tensioner is not supposed to be above the eccentric but next to it so that when turning the eccentric it pushes the tensioner against the chain, this is the case correct ? Here is a picture to illustrate - As you can see the top of the tensioner is above the eccentric in this photo and there is plenty of slack. Any thoughts ? Thanks !
