As with your harley, as with my bike...that last little bit of gas you can squease in there amounts to about an 8th of a cup. That might get you a couple miles in the right conditions.

My bike doesn't have a fuel guage. It has a reserve. It also has a resettable trip meter. I use the trip meter, when it tips 150 miles, I hit the gas station and fill it back up. I do get as much as I can in it, but, at the same time, I don't try to get every drop I can in it. Once it starts bubbling (if you saw me do it, you'd understand, I stop - it's probably about 1-1.5" from the top. Could I squeeze in more, sure can. Might be 10miles more...

But the end result is that I don't gas on me, and I don't want gas on my engine, and I don't want gas ON my bike and all it's parts that would have to be cleaned else risk damage...(leather)

So...with the Z...I don't want gas on the paint. I don't want to risk damaging parts to the Z that would be more expensive to replace than getting a tow, or calling a buddy with an out-of-gas story...
