Isn't it great how something as simple as an oil change can create so many problems? So I was doing an oil change on my fiancee's GS500F, and I noticed the rear sprocket was trashed. No worries, just get a new sprocket and chain. Well, I got all that in and started working. Got the old chain and sprocket off, got the new one broke down to the right length, and got the new sprocket on. I went to feed the chain onto the countershaft sprocket and noticed it was a little loose. No problem, just pop the cover off and snug it up. Well, I opened up the cover and found this: They were stuck in the accumulated road grime/chain lube crap under the sprocket, here: At first I thought it might be a guide, like this one on the cover: But there are way too many of them. Plus looking at the second picture, there's no need for them on the other bolts, plus according to ron ayers microfiche there is only one. Any ideas? Chain exploded on the PO (My fiancee bought it with 2500 miles, it's got 30k now) and these are what's left? Any help is appreciated.
