hello! Today i tear down my sons xr70,and replace the cam chain roller. The bike was running really rough, and was very noisy. one of the previous owners had this top end apart.They did not put this bike back together right and as a result, the bike had some problems. This video is on an xr70 but should cover similar models XR50,CRF50,XR70 &CRF70 • 1997-2016
