Does anyone track day or race a GSXR 1000?

I'd like to know what your fuel consumption is like and it would be great to know anyone who has measured out the correct amount of fuel to last a session.

This all relates to my thread in the racing section HERE but I figured I'd get a better response in this one.

Any info welcome.

Thanks.

I ran an 07-08 1k. It gobbled fuel. I used 10-15 gallons a day at track days.

I assume you are trying to only carry as much fuel as is needed to save weight? Get a wooden dowl rod and a Sharpie marker. Start with an empty tank and pour in 1/2 gallon. Dip the dowel and mark it with the sharpie. Repeat every half gallon until the tank is full. Now you have a tool to gauge fuel consumption. Fill the tank, run a session and then use the stick to measure what is left. Now you know what you used, so you can adjust downward until that amount of fuel plus a safety margin is all you put in before a race. The reason I suggested starting at 1/2 gallon is because below that, you may run into starvation issues during extreme cornering and braking. I suggest you try to have at least 1/2 a gallon in the tank at the finish.

Bear in mind that a red flag and a restart could run you dry if you cut it too close. Also, faster tracks use more fuel than slower tracks and gearing changes will also effect consumption. Experiment and keep notes. You didn't think this was going to be easy, did you?

Great advice here, and this is what most of us do when we want to measure fuel. I never got that critical, I would always add two gallons per race. That made the bike consistent in terms of weight, and allowed for a red flag or two.

I know the real fast guys, like Jim Cohrs and Mark Miller Jr. would have graduated cylinders and measure out their fuel exact. They even knew how much fuel to add to compensate for a red flag. But then again, they weren't using pump gas either.
