Grinding, " diesel " noise under valve covers

Man, I hope not! I took a video, but wouldn't post. It sounds like the rockers are " grinding " or more like a Growl, kinda like a diesel..is it possible the timing of the dizzy caused permanent damage.? Oh , and not trying to get in your business, but how are Things Down Under? The media here keeps us in the dark...
You need to host it on youtube first and then post a link here. This site will not host videos.
