Pterodactyl and I recently took a very agreeable lunch with noroomtomove and his delightful wife at their very agreeable house where, ironically, there's plenty of room to move.
Pterodactyl and I were moving on after lunch to a destination nearer Phillip Island and the conversation—as it inevitably does with CB1100 owners—moved on to where our next fuel stop should be. It's an issue with the CB1100 because it doesn't carry an enormous payload of fuel and the 2010 and 2011 models sold in Australia—like the 2013 model in the US—don't have the fancy computer that tells you how many miles/kilometres you have to ride.
Noroomtomove suddenly announced, "It's easy. When the reserve light starts blinking I know I've used 10 litres of fuel. I divide the distance I've travelled since I filled up by 10 and then multiply by 4 which tells me how many kilometres I have left to run."
An example: The reserve light starts flashing at 201.3 kilometres. Divide by 10 = 20.13. Multiply by 4 = 80.52 kilometres left before there's a hideous sputtering and the bike stops.
The formula for Noroomtomove's First Law of Motion and Fuel Consumption can be expressed thus:
KR = KT/10 x 4
Where—
KR = Kilometres remaining; and
KT = Kilometres travelled
Why 4, I hear you ask. Because the CB's tank carries 14.6 litres of fuel which means that, with 10 litres gone, 4.6 remain. 4 is near enough as a multiplier for a back-of-the-fag-packet calculation and leaves a margin of error.
Now Pterodactyl and I are naturally cautious and believe we are slightly harder on the right wrist than noroomtomove, so we decided to use 3 as the multiplier to give us some margin of error. A later check with the manual said that, if the tank is level, the reserve light will start to flash when approximately 3.6 litres remain in the tank. As the tank is said to hold 14.6 litres, the calculation should be based on a divisor of 11 and a multiplier of 3.6. However, if, like me, you're a mathematical klutz and can't use a calculator without pulling over, noroomtomove's first law is pure genius.
Neither Pterodactyl or I ran out of fuel, but then we never have. We did push on further for our next refuel than we otherwise might have. However, I can say that application of the Law gave me much greater comfort than I have ever had when running close to the line.
Thanks noroomtomove.

I got to the junction and there was nothing there. Ended up riding another 24 miles with the gauge flashing before reaching a little town a small gas station/convenience store.
