Hey there i have a 1994 dr350se which i recently messed up pretty hard by oil starving the head. I took apart a valve cover from a dirt model and put the rockers onto my SE. The rocker arm shafts are different for the exaust and intake side and i'm not sure which is which. I have two hollow shafts that have two holes in their sides, and i have two shafts that are solid besides for the threaded hole on the end for removal. Does anyone know which goes where? I can post pictures later. Thanks for any help.
