someone over at wildguzzi commented on missing bearings, so I do believe it happens,
Hard to think why it would until it happens to you. I only discovered it because it is an old bike in need of a fix.
Shiloh, are you the one who originally posted on the Kawasaki forum? With all the cross-posting I'm trying to figure out how many missing bearings there really are.
