Loving my (new to me) gz

[bwinge250]

First off, thanks to those who replied to my newbie post awhile back when I was having trouble with lights, idle speed, starting, etc. Turns out I got a bad battery but replacing that solved most of the issues. Still have a bit of a hang idle but not too bad. I've been riding non-stop ever since and I'm really enjoying this bike. I gave her a decent bath today (not showroom quality or anything) and thought I'd post a few pics. Any thoughts on gas grade? A buddy told me to use non-ethanol or at least high grade...what do y'all put in yours?
