Thanks for providing those links.
I'm at 13T on the front sprocket, but other than that, mostly stock.
My fuel light comes by 70 miles, but has come on as early as low 60s, but that's not as typical.
Definitely some sand, and I'm not wide open, but we do go kinda fast.
Sounds like on those long stretches where I need more MPG, if I lay off a bit, I should get much more mileage. I'll have to experiment with that.
Maybe I missed it, but in those other links, I didn't see where anybody said how long they rode with their fuel light on. I've gone aboyut 17-18 miles and still had a little left.
