nOOb question here: I've been searching the parts diagrams online (bikebandit.com) but I can't find the right picture. So, I will describe as best I can. I found this broken shim stuck to the magneto when I took my new to me SM apart to do the Stator and Starter clutch LocTite fix, listed in the FAQ area. I looked/felt all over with a powerful flashlight and could not find the missing part. It wasn't in the oil filter or magnetic drain plug. Its possible it left with an earlier oil change, I suppose. The shim is the same diameter as the shaft above the big ring gear behind the magneto. (sorry I don't know the proper terminology) I fixed the doohickey on a KLR once, my only other experience cracking the side covers like this. Any idea where it belongs or if its nothing to worry about?
