Trying to get an idea of real world mpg for a full road race s550 (2018) w/ manual transmission and the 373 gear. Ditching the saddle tank for a fuel cell and trying to determine what size I will need to finish the sprint races we do. I have been told around 4 mpg but don't know if that's low or accurate. Motor is all stock for the class - even will run a restrictor in one of the 2 classes it will run in. Please only real world answers - I can guess all day but trying to solve this before it goes testing and realize the cell is too small lol. Thanks!
