    Well time to pull the cam cover and check things out.
    Look at the timing chain first off as sounds loose. Might be time for a new tensioner and chain.

    It starts,it runs,it gets to where all CRFs can get to without the valve or valve plate dramas

    I agree with Ray , it sounds like the Timing Chain or related component .....
