This is the only thing that I didnt like about the zilla I bought. At some point, a chain snapped or came off and broke the upper sprocket cover boss. . The little bit of threads left actually do hold the cover in place.
I would like to get one of SBLTs case savers, but is there enough meat left here to hold it in place?  Im sure this has happened to other 500s before.
Anybody ever get this kind of thing repaired before?  It will have to wait until the first time I split the cases, but just doin mah homework.
 Update.. The pic wont upload. Sorry. Hope I described it well enough for people to understand.

yes you can repair them.  done a bunch myself. 

Or you could ordwer one of SBLT500's case savers and not have to worry about it. I'll run nothing but now after many years of dealing with derailed chains.

I only mentioned that because I was running an sblt case saver when it broke the bosses off my case.
Nothing against the case saver, it's a great piece and bulletproof...wasn't damaged in the least when the chain let loose.
I'm also not saying that running a case saver is worse than not running one, because sometimes the chain just feeds right through and doesn't cause any damage at all.
Until something like a frame mounted case saver is made, sblt's is probably the best option.

Think about this though, if the case saver was made of chromoly steel and the chain got bound up between the saver and the sprocket, do you think those bosses are going to stay put?
They're going to be ripped clean off the case along with the case saver.
Something attached to the frame wouldn't damage the case and would absorb all of the damage into a replaceable part.
A lot easier to buy a new part than repair a set of cases.

If I can make a picture of it I'll post it in a new thread.
