Hi there, this is my first post for my first motorcycles 1981 Honda CM400C. I have done a couple little things (changed the oil, fixed some wires, and some misc cosmetic stuff) i am now trying to replace my chain, bought the right one and decided to check out the shape of the sprockets. Back one is fine, but the front one seems loose. It seems like there should be a spacer in between the sprocket itself and the shim. Can anyone help me with this? Much appreciated!
