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.
