After match-mounting by either of the above methods, the tire/wheel assembly can be balanced.
    That’s good info on the Yokohama tire markings. However, my point all along is that the valve stem is quite often NOT the heaviest point of the wheel assembly. If you blindly make that assumption, then the dots on the tire are a waste of time.

    I don't recall the heavy spot on any of my MC rims being at the valve stem actually; sometimes close, but never at. I put the rim on my balancing rig and mark the heavy spot with a silver Sharpie pen on the inside; then have a reference point for the future.

    Yet another example of a motorcycle wheel that does NOT have it's heaviest spot at the valve, in this case my GL1800. I'm only 1 for 5 on having the heaviest spot at the valve, thereby further supporting my advice that the bare wheel needs to be checked and marked, rather than assuming.

    Do you think the dealer checks the wheel balance before mounting the tire? Not a chance.
