my state of missouri is demanding all fuel sold in mo. have ethanol. it is just a matter of time before this happens. what changes do i have to do to a carb and a fuel injection motor one is a 2002 fatboy carb and the other is a 2006 deluxe fuel injection? i haven't talked to the dealer yet to see what their plan will be. the fuel is suppose to have a least 10% ethanol in them. when i purchased the 2006 they said don't buy any fuel with ethanol in it.
