Howdy Road Scholar!
Congrats on your new ride!

As far as the stock petcock goes, it's my opinion that those Honda engineers are pretty smart when it comes to fuel delivery. But even with tip top maintenance, that fuel valve diaphragm (Cover Set) will eventually go bad. Luckily, it's easy to replace, inexpensive and you only have to do it every ten years or so. Hildr the Valkyrie is on her third cover set.
Could probably go longer than ten years between cover sets on ethanol free fuel. I've been filling up with ethanol free fuel at the Valero just west of Dripping Springs on 290. At $4.12/gal it is no deal, but Hildr seems to love it. Luckily, there's a brand new QT at 290 and FM1826 with ethanol free fuel. I live just off of FM1826 so yeah, the new QT is in the hood! I recently got ethanol free fuel at a QT in Kyle for around $360/gal and I assume the new QT will be at about the same price.
I ride through Blanco all the time and enjoy those restaurants on the square, plus I'll occasionally pop into Liz's on the square to shop. The courthouse has clean restrooms, too! Don't forget, the Marigold Festival is just around the corner (Oct 31st - Nov 2nd).
