Sorry to hear of your troubles John. No real help from me though , those problems are best found by hands on examination. As for the chain , depending where it sat I supposed the O rings could have dried out but never heard of that before. at 10,000 miles that chain should have plenty of life left in it, strange. I never let a chain sit that long before I used it but I have to imagine they sit on warehouse shelves for a while.( probably not 6 years though)
