Gas Guessing

I would think that would be plenty of gas. It all depends on how you ride. If you're always wide open you'll go through a lot more gas than if you lug it all the time.

Yes, even at the rate my bike inhales gas, I can go nearly all day on about 5 gallons.

The most important hill climbing tip, keep your speed up. If you can get that bike in 3rd gear and keep it there, the bike will be so much more stable and track much straighter. It makes the hill almost easy. This works on sandy, slick hills. I don't know much about the rocky ones.

My body would run out of gas long before my bike consumed 6.5 gallons.

When I go out to the desert and camp for a weekend I will generally go through 5 gallons of gas, and that keeps a YZ-250 and a YZ-125 going.

Riding an enduro will burn through quite a bit more, I probably burned 3 gallons just on the enduro but man, I was dead afterwards.

If in doubt, bring extra gas. Don't mix the second can unless you need it, and then transfer just what you think you need to the mix can.
