I had a different problem and I don't think I've ever mentioned it here. When my belt broke in '05, it bent my outer side-plate on the front sprocket. When I pulled it off to fix that I found that the rear bolts were backing out. Needless to say I pulled all the bolts, straightened the side-plate and red loctited all the bolts.
Just an F.Y.I. You gotta watch these parts.
