    yes the one on the left is the newer version
    every year yamaha used pv something failed , them made the fix on the valve and something else on it failed
    there is i think 4 diff pvs before they stopped failing

    Yes, the one on the left was for sure used in 04, and is like teflon coated. Cleans up nicely.
