    What are the symptoms?

    Greetings!

    The Hinckley triples are inherently noisier engines than the rest. 
    The gear whine, the clunky shifter, the tractor-like idle.
    All that is a character of the triple I find unique and charming.

    This brings me to my question. It is more of a, "I am wondering" than anything else type of inquiry.

    When valves go out of specification, i.e get tight, what are the "noises" being heard beyond the scope of the usual suspects such as poor idle, increased consumption, and decreased power output?

    Cheers...

    I do not know if I understood correctly. If the valves are too tight and out of the range recommended by the manufacturer. It's time to do a good review on it. Since you run the risk (among other things) of a disaster occurring.

    However, if the valves are somewhat open and are outside the manufacturer's range, consumption will obviously be somewhat higher than usual, but it is not as worrying as the previous one. The sound will be heard as a continuous rattle, clack, clack, clack. Above all, it will be noticeable when accelerating with a high gear and if it is a journey with a slight slope. That sound disappears when the high gear is reduced.
    Only motorcyclists know why dogs stick their head out the car window.

    I am wondering more about noises people experienced/heard before they had valves checked with consequent valve adjustments.
    Someone must have noticed a change.
    I'd like to hear their experiences. 

    I've had a couple of cars and one bike that had a pinch bolt valve adjuster type set up. The E34 M30 engine has gone from happy noisy to quiet and I was told I should check the valves. I was then young and inexperienced. But with the R1100RS I didn't hear any changes in noise when I discovered exhaust valves were tight.

    No reasons for concern at all.

    I think the issue here is that because any change in noise would be gradual,
    and would change over time, the owner would not usually notice.

    It would seem that if the valve clearances are "loose" ,
    the engine would be noisier with more "rattle". 

    As the valve components wear, the clearances reduce
    which may lead to the engine sounding quieter and LESS "rattly" !  :087:

    The only way to be sure that the Valve clearances are withing specification,
    is to carry out the dismantling and checking processes called for every 20,000 miles.
