I ran out of gas on the way home from work today and had to hit reserve with 50 miles on the stock tank. What the??? All of it was on the road, in town. I know there is some fuel on the left side of the tank that can be moved to the petcock side, but does anybody know about how much stays over there? I didn't try that trick. I just flipped it on reserve while on the go and motored on. I was just really surprised to hit reserve at 50 miles...that just sucks. I have been looking at the 4.3 gallon Clarke tanks in natural so I can see the fuel level. I don't really like how they turn yellow though. How long does it usually take before they really start yellowing???
