mine did the same thing, im having he top end replaced now.

thats what i was thinking along with the rings are you doing it yourself

sounds to me like worn exhaust bearings, or possibly the connuter valve went bad

but if by some odd chance you are burning oil and blowing smoke because of bad rings, then you can pull the top end and do it yourself, not too bad
