Hello everyone, Just happened to find this group while searching for parts for my cs5. I´m 1/2 way through a rebuild of the bike I pulled out of my in-laws barn last year. The auto oiler to the #1 cylinder clogged and seized the rod on the crank end. I just got the crank rebuilt and am in the process of putting the engine back together. I love reading about other people´s experiences with any of my project bikes and maybe I can shed some light on something giving somebody else problems. Thanks.
