Well I checked with the dealer today and they do not have any specs on the chain. I would think half an inch on such a short chain is a bit much in slack but if no one else does then I may just leave it. The cover isn't difficult to get off and I needed to drain the oil anyway to change the clutch. I was just afraid that the bearings or shaft would get damaged due to the "shock" caused by the slack. I understand about being hyper-focused but I really think I would have noticed it before. We are talking over $600 in parts so I am gonna let it go for now, maybe after I do the clutch and rebuild the forks I will take it to see if I can get a tech at the dealer to check it out. Thanks for all the comments.
