I have a 1971 Honda CB500. I'm new to the rebuilding world, but I love tinkering in the garage. So I removed the LH crankcase cover to my bike the other day, no problems getting it off. But when I reinstalled it, the hand lever cable was not engaging the clutch to allow me to shift gears. I never adjusted anything inside the cover, but I didn't do something right when assembling. When I pull the lever everything seems to be working inside the cover. I did have several (maybe 6) small 1/4" orings that fell out of the cover, broken, when I removed it. I'm not sure where they go. My manual doesn't spec them out anywhere. Any ideas how I may have mis-assembled the cover?
