Gas in tank: How much?

[dwilson]

Last time I was at the track I was topping off the FZR & my neighbor makes the comment "what are you running, an endurance race?".  I figure 5 gallon tank = +/- 40 lbs.  The FZR has a rectangular tank under the cover, I figured I could use a wooden rod to measure how much gas is there & keep 2-3 gallons.

The other idea I had is to get some of the foam they use in fuel cells to take up the extra space.  So when I fill the tank I know how much is in there and don't have to measure it out.

So what does everybody else do?

I always go out full.  Better to deal with the extra weight (which I don't even notice)  than run out on the last lap!

Run out on the last lap???  Who would do that?

The fuel foam is a good idea but it takes up almost zero volume it prevents sloshing of the fuel. On a normal size tank I did not notice a difference with or without but on endurance tank with almost 7 gallons it would slosh pretty good at 3/4 tank to 1/2 tank.

The foam almost makes it hard to tell how much fuel you have left.

If you do not have a slosh problem then I would just drain tank add gallon mark on a stick add another gallon and so on til full then do some figuring on how much fuel each track takes for that race then add enough for a restarted race.

Gasoline is about 6.35 lbs/Gallon.

I run about 1/2 a tank at the least. From what I've heard, and SV gets approx 20 MPG on the track, and I'm running 10 total laps, plus idle time.

Some bikes handle better with a full tank...

My bike only holds 3 gallons...lol.  Can't wait to see if I can make it 30 minutes at Daytona. :o

i run as little as possible. My bike is easier to ride light. 1-2 gal at the most. couldnt imagine being out with a full tank for a 6 lap sprint race but thats me..

Can't even feel the difference on mine.  Melka...better get used to running with the heavy tank if you are ever planning on running an endurance race.  By the way, have you though about the Team Challenge at Daytona yet?

We always try to do a race pace fuel consumption run in practicae, then I pad that amount by 1-1.5 liters. Most races we go out with less than 4 liters in the tank.

I would run a usage test during the practice runs.  I could see how much I would use then. (and my bike is a gas hog!) :'(
 Most of the time I could run a back to back on one tank full.  Say, heavyweight and Supertwins, and me pretty good at the end of supertwins[ and lighter too]. ::)
  Try what you want, but remember this, you run less risk of exploding on impact with a full tank. ;D

 I fill ine to when i can see it as a shake the bike. Sometime i go out full. I dont really feel a difference
