Yes that's right.....one mile per one ounce of 110 octane VP race fuel. Does that sound about right?
EDIT: No that doesn't sound right at all as that would be 128mpg which isn't even close. It used to get 80mpg on a good race day, now I would guess maybe 45mpg.
It is a gas guzzler on the track.....
45 mpg is believable, but I hope it's better than that. That would be really low efficiency with only 20 hp. My 85 hp Sportster running wfo gets 30+ mpg.
