To determine whether or not it's gray market, you can go to Yamaha's website, look for the serial number/mfg year page, then enter the ser#. If it's gray market, it will tell you. It will also tell you that they do not supply parts for gray market pianos in the US. That said, the only thing I can think of about gray market that may bring about the tuning instability, well, I don't think it applies significantly in Houston... where it's pretty much always humid by my recollection. I service one gray market G3A here in the land of dry indoor winters. My first appt with it was in February a couple years ago and I measured RH at 26% and it's still holding up fine. I've also seen a used one marked way way way down at a large music store... mighta had sumthin' to do with the 3-4mm cracks (plural) in the soundboard. Also, the one I service has a tuning record card in Japanese, as well as a decal inside the rim with "Yamaha Piano", and some Japanese.
