Mix 40:1 (twice) with 91 and ride till you empty one gas tank on flat. Or you can do half and half of 91 and C12 but it has to be jetted at 340 or 350 and again empty one gas tank on flat. Then gradually break it in by doing 3 gallons of C12 and 2 gallons 91. Then to 4 gall of C12 to 1 gall of 91 to the end of full C12 racing fuel.
