I have a Honda XL185S, and during a recent oil change, this piece of crankcase dropped out of the case with the oil. (see pictures) I split the cases, and found that it is a little piece that comes from here. Who knows how long it was like this. I think that the purpose of the piece is to stop the kickstarter from over rotating. That really shouldn't be a big problem considering the spring that returns the kickstarter. Does anyone see any problem with buttoning the case back up the way it is?
