400 EX chain/sprocket

[winger]

I just put a new RK chain and sprocket kit on my 400 EX. New chain and sprockets. For some reason the chain does not ride in the rear sprocket correctly. Chain rides correct in center of sprocket but the rollers are riding up on the sprocket teeth on the top and bottom. Meaning the roller part of the chain is on the point of the teeth. Chain is adjusted as specified in manual. Am I missing something obvious or is it possible the sprocket was packaged wrong? Right now the chain rubs the guard under the rear spocket. I've changed these things before but never had this happen.

Just an update. Apparently a mistake was made when RK packaged the kit . The wrong sprocket was packaged. They are sending me a new kit. Apparently this has happened before. Good to know that I'm not totally going nuts.
