Default Fuel Mileage stock v modded

I am terribly curious how many of you keep detailed records of fuel in your bikes through the seasons. I have every receipt for every gas fill in my Vic, with the mileage written on it so it's very easy to figure out my mileage for a given time period.
And I know fairly well what has improved my mileage, a for instance being the muffler mod and ditching the O2's.

Now the question is directed to anyone who has ditched the kittens Did it improve your fuel mileage or did it hurt it?

Not concerned with heat reduction, loss of torque, making it louder, or any of that. Just straight up honest to goodness fuel mileage numbers

As long as it tuned right you shouldn't lose much if any at all. You will have to remember that you will be throttle happy for the first little bit so that will effect mpg's.

Is the ultimate goal to get the best fuel mileage possible? Let me ask, what have you learned from the meticulous fuel records? Have you discovered what modifications improve fuel economy? Have you found what is detrimental to fuel economy? What is the data giving you? Is your fuel economy consistently getting better over time?

Great fuel economy is a product of the engine being EFFICIENT at converting air and gasoline into forward motion. Personally, have never given gas mileage a thought when modifying the bike, it was never tuned with fuel economy in mind, or ridden with fuel economy in mind. I have never kept records of the mileage. That said, whether it was making 120 or 130 HP at 104 or 110 cubic inches, it has averaged 45 mpg. If I get on the highway and cruise at 3000+ rpm I get 48 mpg. Riding with others I always take less fuel at gas stops than everyone else no matter what we are doing... and I'm the guy pulling the front wheel up, staying out of 6th gear, and shifting at 4000 rpm... go figure. In a slow group ride I have returned 50 mpg several times.

My friend, Joe, can get better fuel economy than I do simply through riding style. When we used to ride identical bikes except for color and trade back and forth... no matter what, he could ALWAYS pull 1-2 mpg better fuel economy than I could. Just the way he rides... He's just a wee bit more 'gentle' than I am. I remember on a trip we did, one particular tank, we were calculating mileage at the same time using the lowest odo reading and accounting for gearing. I said, "I don't believe it! 49 mpg!". He turned his phone around... 51.

My brother (RIP) and I would often have the same cars and/or the same bikes. Like you, SD he was OCD about mileage, writing down every fill up with the goal of keeping the numbers high as possible. We had a hard time riding together cuz I would have to stop for gas before he did cuz I was usually using lower gears and more throttle. One day he chipped at me for that and I told him that its like going to the theater, you pay more for a more exciting show. He never said anything about my lower fuel mileage after that. If he was still around, I know he'd have a Victory too and although our riding styles are different, we'd be getting similar mileage. I know that for a fact cuz my mileage did not change after my mods.
