Donk I am fostering Junk Jacketís bike here. It needed a good home.

the Ferret Donk, you bought another FJR?

Donk I donít understand what all this is about the fuel gauge. Iíve owned 2 Ď14s and now a Ď19. When I fill up the tank the gauge says full. As I ride it goes down proportionately as the miles go up. When it gets to empty I have about a gallon reserve left. Been exactly the same on all 3 bikes. Couldnít ask for better.

slowdave We're not nearly sophisticated enough to slow down to save fuel! Never good enough info to know where we are on fuel that accurately. And no reserve petcock setting anymore. And I think in my ~20 years of endurance racing, we've had a functioning low fuel light about 20% of the time. So we just run it to an hour or 1:15 and see how much it takes to refill and adjust for the next stint. Over time, build up some history and knowledge until you change bikes and start over again. And then there's rain. Lots of guessing.

Bravery is riding a 2-stroke in endurance racing!

In the endurance stuff though we're normally going on gals/hr and just trying to not run out of fuel on the far side of the track in the middle of the stinking 6 hr race. And trying to stretch stints out to the max (hour 15 or 1.5 hours). Good times!

Side note: fastest guy on the team, even if by 1 second/lap, ALWAYS burns the most fuel/hr. Hmmm.

We endurance raced an RD400, and a tank of gas was about an hour. There was no fuel gauge, so we had to use reserve on it.

Fuel strategy has been very important in some very important races. Alexander Rossi and the 2016 Indy 500 comes to mind. It must be agonizing to have to try to conserve fuel to make better time.

It was the end of my second or third track day. Its great if you can pace yourself and skip a session at some point because most riders get tired and pack up before the last two sessions. The you can ride with 3 or 4 instructors and get some huge input from several quality people.

One of the instructors asked me. "What was all the business in the braking zone for turn 1"?

I said kind of flippantly. "I ran out of gas and was switching to reserve".

He rolled his eyes, turned and left. The other two stared at me for a second and then just continued with some tips.

That was the day I discovered my Bandit which usually got 35 to 40 mpg in mixed riding was getting about 16 at the track.

I got my first bike with a gas gauge in 1984. My bikes with reserve have stayed on Reserve since. My ZRX has a reserve petcock, and it's been on reserve for 21 years. After getting stuck at lights a couple of times I always anticipated anyway and switched it to reserve when the odometer told me it was about time.

Same here. A couple of times it started sputtering while I was sitting at a light with my clutch in in low gear trying to turn left. That was inconvenient.
