Any input on measuring fuel in the tank between sessions?

So I've been pitting with a buddy of mine who measures the gas in his bike after every session then refuels to a set amount for the next session. He uses a siphon to pull out all the gas into a measuring container and measures the remaining gas, then adds whats needed or makes adjustments depending on what he's trying to do, so he's never carrying unnecessary weight.
Me being me, I've adapted his procedures but I want to improve on it if I can. I ordered an 8 quart oil container with a spout off Amazon to use as my measuring container. Just need to get a siphon and I should be good.
I wanted to see what everyone else was doing and using.
Thank you

 

measuring stick. marked in liters / quarts

put in 1 liter, put stick in, notch where fluid ends.

do not rinse, but repeat.

cheap and accurate, if sick is inserted with repeatable position / angle and accuracy

 

When Tgold welded up the endurance tank to increase the capacity he also welded in a slot and some fittings to hook up a clear fuel line as a sight gauge. Each mark on the tube is one gallon

 

Why?

 

improve on it? Put a petcock thats accessible on the sump of the tank and gravity drain it while you do other stuff. Obsessing over fuel load between races or track day sessions?

 

I like the stick idea because then there is no siphoning to check the level.
This is what I had in mind container wise. Measuring container & funnel combo.
We did this last year for my track days but racing this year.
I was curious to see what everyone else was doing because I see different Measuring containers in the pits but never thought about it till the off season.

 

Fuel has weight..couldnt you just scale it ?

 

Looks Factory!

 

+1 to a marked stick

Red flags during club racing are really stressful if you are running tight on fuel, especially if you don't have much help in the pits. Sometimes you'll barely have time to take your helmet off and put warmers on. Taking the time to add fuel and stressing about it is time that you could be relaxing and cooling off instead. 50-100% extra fuel fixes that. For a club race, that's not even 10lbs.

 

I guess its like folks removing the radiator fan to be a weight weenie for 1lb til they boil over on the grid on a warm day.

 

Ok ok ok, yes I know I'm overthinking this lol. I was just pondering about it. I use to fill 'er up at the beginning of a track day and fill 'er back up on lunch and be good for the rest of the day. Then I was slapped up side the head with a remark like, " hey you know your carrying like another 20lbs than you need to be!" So I've been doing this fuel regiment for the second half of last season. I'm lucky I got a pit helper (wife) and I'm pretty much only checking gas and doing my helmet. Thanks for all the responses!

 

No need to worry about making a rule Mongo. It was a giant pain in the ass to weld so the the chances of there being another person dumb enough to waste that much time should be low.

True story: My wife commented that our electric bill was pretty high not long after I finished it

 

For a track day??????

Did you win Track Day? You never mentioned that this tech tip helped you win or not. I'm on pins and needles here.

 

Lol, no I definitely never have won a track day but I can promise you I have definitely DNF'd a track day.
But, yes. About halfway through last season, I started pitting with a good friend of mine who races. His racing habits have worn off on me in the pits in preparation for me to race.
