Thanks for your responses guys. If it was a belt or an accessory going out would it stop making the noise after driving? I'm not sure when the last time the valves were adjusted, but I do know the HG was changed 15k mi ago and the PO claimed the valves were adjusted then, so its probably time to do it again....right? The other thing I was thinking is maybe the clacking is caused from lack of oil? Like maybe upon start-up not enough oil is getting to the head, isn't there some issue with the banjo bolts?
Thanks in advance.
