Thanks...I have read that other posting about 100 times already to make sure I knew what I was getting into. :)
I actually ended up not replacing the sprocket as I decided to wait for the parts you mentioned.
I did take the cover off last night with plans to replace it, however, it seems there is a tabbed washer of some sort behind the nut. One side folded over to help prevent the nut from backing off. Looks like I need a replacement for that washer before I can even think of taking that thing apart.
It looks like the tab is only possible on one side of the nut...does that make sense?
I was expecting to be able to re-use the nut/etc as the bike is only 3 weeks old with 600 miles on it...
It is going to the dealer tomorrow for it's 600 mile service, so I may just have them do it while it's there...hate to pay to have someone else do this type of thing though. I even went out and bought a torque wrench just for this!
Thanks for the pointer though...the lc4 index is awesome, one of my favorite places on this site since buying my new 640. :)
